Founded in , Zoom is the leader in modern enterprise video communications, with a secure, easy platform for video and audio conferencing, messaging, and. The integrations are available in the Zoom App Marketplace. the integration will be enabled if it meets Stanford security requirements. Zoom advertised a security measure, known as end-to-end encryption, that would protect messages between senders and their designated recipients.
 
 

Zoom app marketplace security – none: –

 

Although versions lower than TLS 1. All connections and endpoints made available by your application to Zoom are required to transfer through TLS protection. All apps developed on the Marketplace are given unique credentials which enable them to securely access account data and make changes on behalf of itself and users who have installed the app.

API credentials, SDK keys, and Client secrets must never be exposed in client-side apps, local storage, or in a public repository. The following fields should never be logged or stored in cleartext, and should be encrypted at all times when at rest:.

If necessary, app credentials can be regenerated from the Marketplace Dashboard of each app. URLs could also be displayed in history, bookmarked or emailed around by users. They may also be disclosed to third parties via the Referer header. It is highly recommended that all apps receiving event data from Zoom through Webhooks verify that the incoming request is coming from Zoom. Without doing so, event notification endpoint URLs could be vulnerable to fraudulent requests and denial of service attacks.

Event notification endpoint URLs are the endpoints of your application which are set to receive notification data from Webhook events. To secure an event notification endpoint URL, verify that the value contained in the authorization field in the incoming request matches the verification token created when event subscriptions are successfully added to your app.

Ensure that sensitive cookies are marked with secure and httpOnly flags. Implement the use of Content Security Policy or X-Frame-Options headers where necessary to ensure the app is not vulnerable to clickjacking attacks. While framing is a feature, it can also pose as a security threat without insufficient measures in place.

Please ensure that this feature is securely implemented. Logging information for app debugging and diagnostics is an important function to understand app and system performance as well as to identify vulnerabilities and malicious intent.

Security-focused logging should be used to identify any potential attacks and enable responses to secure or invalidate a user session or token. If submitted data or suspicious user activity is detected, encoded information on the session should be sent to a secure logging service. Do not ever log sensitive information. Errors reported during app usage are commonly used to report information directly to a user, but this provides the risk that data provided to the user within a client could also provide information useful to an attacker.

For example, it is possible that information within the error response could be used to determine sensitive information and the existence of user accounts. Information leakage is a common vulnerability that exposes data through error codes shown to users which include common debugging information, stack traces, or failed database queries.

You may have to install the update “manually” by downloading it directly from the Zoom website opens in new tab. Zoom’s client software for Windows and Mac personal use now lets you enable automatic updates opens in new tab , which means you’ll get all the latest crucial security fixes as soon as they come. Even better, the new feature lets you choose a “fast” or “slow” lane for less urgent updates, meaning that you can choose whether to get all the latest features and risk a little instability, or to proceed at a steady pace with maximum reliability.

Automatic updates will probably be enabled by default soon for all new and existing users. As a result of a settlement in a class-action lawsuit relating to some of the privacy and security issues detailed earlier on this page, anyone who used Zoom between March 30, and July 30, is entitled to a cash payout.

It might not be a lot of money per person. To file a claim, read the fine print at ZoomMeetingClassAction. Tom’s Guide cannot guarantee that you will get anything. Zoom has patched three serious flaws in some of its enterprise video-conferencing software, the worst of which could have let an attacker penetrate a company’s internal server system. The following enterprise Zoom applications are vulnerable and must be updated, per a report from Positive Technologies opens in new tab : Meeting Connector Controller up to version 4.

Regarding consumer software, Zoom has fixed a security flaw in Zoom Client for Meetings for Windows, which needs to be updated to version 5. That’s according to the Zoom Security Bulletin opens in new tab page. Zoom announced that beginning Nov. Anyone running software older than that will be prompted to update their software.

This affects all Zoom software running on all supported platforms except for Zoom Room Controller software, at least for now. Zoom disclosed several security issues opens in new tab that had been fixed in later versions of Zoom’s desktop clients and plug-ins for Microsoft Outlook for both Windows and macOS.

The flaws ranged in severity from low to high, with some allowing remote code execution — i. All were patched by at least Zoom Client for Meetings 5. Zoom announced that it planned to roll out end-to-end encryption opens in new tab to Zoom Phone opens in new tab , its paid cloud calling service for Pro, Business or Enterprise accounts.

The end-to-end encryption will be an option for one-to-one Zoom Phone calls. Zoom announced via its Zoom Security Bulletin opens in new tab that the remote-hacking flaw demonstrated at the Pwn2Own competition in April had been fixed. Zoom reached a tentative settlement in a federal class-action lawsuit that alleged the company skimped on security, misled users and shared user personal data with third parties without notification or consent.

Enterprise and government Zoom account holders are not part of this litigation. Known class members will be notified by email or regular mail that they can file a claim, and others will be able to use the website www.

Zoom has released a ” simpler, clearer opens in new tab ” privacy policy that reflects the fact that the online meeting service has “shifted from a primarily enterprise-focused product to one that is also used broadly by individuals” during the COVID pandemic. The updated privacy policy includes more details about who can “see, save and share” Zoom meeting content, and the kinds of data that Zoom collects from users’ devices. You can read the full updated Zoom privacy “statement” here opens in new tab.

In a blog post, Zoom announced that it had added privacy notifications opens in new tab to the latest version of its desktop client software. The notifications appear in the in-meeting chat window as a button labeled “Who can see your messages? It added that future updates would include notifications when a meeting host or participant uses a Zoom transcription or scheduling app during a meeting. Two researchers demonstrated at the Pwn2Own contest that they could remotely take over Windows PCs and Macs by using at least one previously unknown vulnerability in the Zoom desktop application.

Fortunately, the only people who fully understand how this exploit works are the two researchers and Zoom itself, which is working on a fix. The chances of this attack being used “in the wild” are low, but if you’re concerned, use the Zoom browser interface instead during meetings until this is fixed.

Zoom lets meeting participants share all of their computer screens, part of their screens, or just specific application windows with other people in the same meeting. Two German researchers discovered that for a brief moment, the entire screen may be visible even when the Zoom user sharing the screen intends only part of the screen to be.

Any participants recording the meeting would be able to freeze frames during playback and view potentially sensitive information. Zoom said it was working to fix the issue, but at the time of this writing, the flaw was still present in the latest version of the Zoom desktop client software for at least Windows and Linux. Keybase, an encrypted social-media verification system and chat app bought by Zoom in May , had a serious flaw opens in new tab that preserved images in online directories even after the user had deleted them.

The flaw was reported to Zoom in early January , and a Keybase software update to fix the flaw was released later that month. A new study conducted by researchers at Boston University and Binghamton University found that efforts to stop “Zoom bombing,” such as requiring passwords or making attendees stew in “waiting rooms,” often won’t work. That’s because many attacks are carried out by “insiders” who are already authorized to be in the meetings.

The “only effective defense” against such insider attacks, the paper argues, is to create “unique join links for each participant. Plagued by an epidemic of Zoom-bombing during city-assembly meetings, the city of Juneau, Alaska is exploring ways to outlaw the practice. Police in Alaska’s capital have had a hard time tracking down the Zoom bombers. The city hopes that by making the practice illegal, it can compel Zoom to turn over information identifying the digital miscreants.

In a bombshell announcement, the U. Department of Justice opens in new tab said it had issued an arrest warrant for former Zoom executive Jin Xinjiang, aka Julien Jin, who until recently had served as the liaison between Zoom and the Chinese government.

The U. Jin is thought to be residing in China. Jin allegedly had help from unnamed co-conspirators who created fake email accounts and Zoom accounts in the names of known Chinese dissidents “to fabricate evidence that the hosts of and participants in the meetings to commemorate the Tiananmen Square massacre were supporting terrorist organizations, inciting violence or distributing child pornography.

The Dept. The DoJ announcement and arrest warrant opens in new tab refer only to an unnamed “Company-1” as Jin’s employer, but in a blog post, Zoom admitted that it was the company opens in new tab and that it had been conducting its own investigation after it received a subpoena from the U.

The post further explained that Jin had been hired by Zoom in October as part of an agreement with the Chinese government, which in September had “turned off our service in China without warning. The price of getting Zoom turned back on in China was to hire “an in-house contact for law enforcement requests” — i.

Zoom service was restored in China in November , and the Dept. Zoom admitted that Jin “shared or directed the sharing of a limited amount of individual user data with Chinese authorities,” and that the information of “fewer than ten The Better Business Bureau opens in new tab is warning Zoom users that scammers are trying to steal their usernames and passwords via phishing emails and text messages, reports Threatpost opens in new tab.

The messages tell you that “your Zoom account has been suspended” or that “you missed a meeting,” and offer a helpful link to log back in. But don’t fall for the bait — the login page is really a trap to capture your Zoom user credentials, with which the crooks can use or even steal your Zoom account.

One of the biggest problems with Zoom has been “Zoom bombing,” in which uninvited participants crash a Zoom meeting and disrupt it. Over the weekend, Zoom released two new features to combat this.

One, “Suspend Participant Activities,” lets the meeting host pause the meeting, kick out disruptive participants, and then resume the meeting. The other, “Report by Participants,” extends to meeting participants the ability to report disruptive participants, a remedy that previously had been given only to meeting hosts.

The Federal Trade Commission announced that Zoom “misled users” and “engaged in a series of deceptive and unfair practices” regarding its own security.

The FTC cited the fake end-to-end encryption uncovered in March and software that Zoom installed on Macs without authorization in and Zoom must agree to yearly internal security reviews and external security reviews every other year and must implement a vulnerability-management program. Another stipulation was that Zoom offer customers multi-factor authentication , which it has already implemented.

Researchers in Texas and Oklahoma discovered that it’s possible to tell what someone is typing during a Zoom call just by watching their shoulders and arms. Any kind of video-conferencing platform could be used for this, the researchers said, as could YouTube videos or streaming platforms like Twitch. Zoom’s end-to-end-encryption feature finally went live, except on iOS where it had to wait for Apple’s approval.

We’ve got instructions on how to enable Zoom’s end-to-end encryption. After a long period of time with no Zoom news, the company announced that the end-to-end encryption it had been working on for many months would soon be available for beta testing. Users will have to wait for a Zoom client software update in the third week of October.

Meeting hosts will be deciding whether to make a Zoom meeting end-to-end encrypted. Those meetings will not work for now for users trying to join via the web-browser interface or over the telephone. If you recall that the Zoom web interface was out of commission for a few days back in April , now we know why: The company was fixing a very serious security flaw that could have let anyone join a private Zoom meeting.

British security researcher Tom Anthony opens in new tab detailed on his blog this week how he found that he could make endless random guesses on the 6-digit PINs Zoom assigns to private meetings.

That’s a million possibilities to go through, which might be tough for a human, but isn’t hard for a decently powered PC running multiple threads. Anthony found he could break into Zoom meetings in about half an hour, give or take.

That’s long before many meetings are over. An unnamed security researcher found a critical flaw in the Zoom meetings client software for Windows that would let a hacker remotely take over any PC running Windows 7 or earlier. Zoom fixed the flaw with a software update soon after the flaw became public knowledge. Backing down after sustained criticism from privacy advocates, Zoom announced in a blog posting June 17 opens in new tab that its upcoming end-to-end encryption E2E wouldn’t just be for paid users any more.

The millions of people who use Zoom for free for school, socializing and work would get end-to-end encryption too. Yuan wrote. But if you’re a free user who wants E2E, you’ll first have to verify your identity to Zoom via a one-time-password or similar service. This will make it harder to “zoom bomb” meetings. The E2E encryption will remain an optional feature, Yuan reminded, because when it’s activated, no one can join a meeting over the phone or with certain office teleconferencing equipment.

It’ll be up to meeting hosts whether to activate E2E. Zoom’s in hot water in the U. The company apologized for the actions in a blog post June 11 opens in new tab and said it would develop a way to block meeting participants from certain locations i.

That wasn’t enough to satisfy more than a dozen U. Yuan demanding to know how cozy his company was with the Beijing government. Talos opens in new tab , an information-security research firm owned by Cisco, revealed June 3 that it had found two serious flaws in Zoom client applications, both of which have now been patched.

The first flaw opens in new tab would have let an attacker use a specially created animated GIF placed in a Zoom meeting chat to hack Zoom client software on other people’s machines to force the installation of malware, or, as Talos put it, “achieve arbitrary code execution. The second flaw opens in new tab also involves the chat function in Zoom meeting client software, with similarly serious potential consequences. The problem was that Zoom did not validate the contents of shared compressed files such as.

An attacker could have sent malware in the form of a compressed file to a user via Zoom meeting chat, and the user’s Zoom client would have saved and opened the malware within the Zoom application’s directory. Even worse, if the user were to save the Zoom compressed file elsewhere on the PC, such as on the desktop, then the attacked could send an altered version of the first file with the same name.

Zoom would open the second version but not the first automatically, permitting the malware to “plant binaries at almost arbitrary paths and Zoom’s upcoming end-to-end encryption is mainly for paid users, as Zoom itself stated back on May 7. But Alex Stamos, a well-known information-security expert who is consulting Zoom on security matters, told Reuters opens in new tab last week that schools and other non-profit enterprises might be able to also get the end-to-end encryption for their accounts.

All administrators of Zoom Rooms need to update their software opens in new tab by May 30, Zoom said in a blog posting May The update to Zoom 5. More information about updating Zoom Rooms is here opens in new tab. The 5. Two more instances of corrupted Zoom installers were found by Trend Micro researchers. The first opens up a backdoor on a PC; the second spies on the PC’s owner with screenshots, keylogging and webcam hijacking and drafts the PC into the Devil Shadow botnet.

Both installers do install the Zoom software client, so victims may be none the wiser. As always, get your Zoom software straight from the Zoom website at Zoom. Zoom suffered an unexplained outage Sunday, May 17, rendering it unavailable to thousands of users in the U.

The outage, which began Sunday morning U. Even the British government’s daily coronavirus briefing opens in new tab was affected, knocking out the ability of journalists to ask questions over Zoom. Some users reported on Twitter that logging out of Zoom accounts, then logging back in, seemed to solve the issue. Zoom’s status page noted that a backend update had taken place earlier Sunday morning, but there didn’t seem to be any linkage between that update and the outage that began a few hours later.

The Zoom status page opens in new tab said at the time that the outages “appear to be limited to a subset of users” and that Zoom was “working to identify the root cause and scope of this issue. Cybercriminals may have registered hundreds of new Zoom-related website addresses in the past few weeks, according to researchers at Israeli security firm Check Point opens in new tab.

Many of these sites are being used in phishing attacks to grab victims’ Zoom usernames and passwords, and similar scams are leveraging rival video-conferencing platforms such as Google Meet and Microsoft Teams.

Over the weekend, online vandals hijacked the graduation ceremony at Oklahoma City University opens in new tab , replacing the Zoom video feed with racist language and symbols. It wasn’t immediately clear whether this was a result of regular Zoom-bombing or if the attackers used less well-known methods to disrupt the video feed.

Zoom announced May 7 opens in new tab that due to its technical-support staff being overwhelmed with calls, it would be able to give personal technical assistance only to “owners and administrators” of paid accounts.

In other words, any user, owner or administrator of a free Zoom account, and end users of paid accounts, won’t be entitled to human help. Instead, they’ll have to rely on the FAQs and how-to’s list on the Zoom online resources opens in new tab page. For now, this provision applies only to May and June If the coronavirus lockdown last longer than that, Zoom may have to hire more tech-support staffers. New York State Attorney General Letitia James’ office reached an agreement with Zoom opens in new tab May 7 following an investigation into Zoom’s security and privacy practices.

There isn’t a lot of new stuff in the agreement. Most of the stipulations Zoom agreed to are things the company is already doing, including making passwords mandatory and using better encryption. In the long term, Zoom has to conduct regular code reviews and conduct yearly penetration-testing exercises, in which paid hackers try to break through the company’s defenses.

Only two new things will directly affect consumers. It also has to update its Acceptable Use policies to ban “abusive conduct include hatred against others based on race, religion, ethnicity, national origin, gender, or sexual orientation.

Frankly, these are longstanding standard policies at many other online companies, so we’re a little surprised that they weren’t already Zoom policies. Yuan announced opens in new tab. The purchase price or other terms of the deal were not disclosed. Keybase makes user-friendly software to easily and securely encrypt messaging and social media posts.

In March, Zoom had to admit that its touted “end-to-end” encryption was not the real thing because Zoom’s own servers are always able to access the contents of meetings. Once Keybase’s technology is incorporated, that will no longer always be the case.

Meeting passwords and waiting rooms will be required by default for all Zoom meetings, free or paid, beginning May 9, Zoom announced. Only hosts will be able to share their screens by default, but like the other settings, that can be changed. Yuan said the massive increase in Zoom usage since the beginning of the coronavirus lockdown had been “challenging,” but also provided “opportunities for us to drive meaningful change and improvement.

Yuan admitted that “we failed to set pre-configured security features for our new customers, especially for schools,” referring to meeting passwords and waiting rooms.

That resulted in “uninvited, offensive, and sometimes even truly evil people disrupting meetings,” Yuan wrote. Such a person disrupted a Zoom meeting on sexual violence opens in new tab in the Bay Area last week.

Yuan also addressed rumors about his own, and Zoom’s, ties to China. He said he had lived in the U. A reporter for London’s Financial Times resigned after he was caught crashing internal Zoom meetings at rival London newspapers. Mark Di Stefano announced his resignation on Twitter opens in new tab after The Independent opens in new tab documented how Di Stefano had last week joined an Independent staff meeting regarding pay cuts and furloughs, first under his own name, then anonymously.

Di Stefano cited his sources as “people on the call,” The Independent said. The Independent also found that Di Stefano’s cellphone had earlier been used to access a Zoom meeting at the Evening Standard, another London newspaper. That meeting was followed by a Financial Times piece about Evening Standard furloughs and pay cuts. Zoom isn’t the only video-conferencing platform to have questionable privacy policies, Consumer Reports opens in new tab said in a blog post: Cisco Webex, Microsoft’s Teams and Skype, and Google’s Duo, Meet and Hangouts do too.

Consumer Reports said you should know that everything in a video meeting may be recorded, either by the host or another participant.

It also recommended dialing into video-conference meetings over the phone, not creating accounts with the services if possible, and using “burner” email addresses otherwise. After prodding from reporters at The Verge opens in new tab , Zoom admitted that it did not in fact have a recent peak of million daily users, as stated in a blog post last week. Rather, Zoom had a peak of million daily “participants.

Researchers at Trend Micro spotted another Zoom installer file that had been corrupted with malware. In this case, it’s spyware that can turn on the webcam, take screenshots and log keystrkes, as well as collecting diagnostic data about the system it’s running on. It also installs a fully working version of the Zoom desktop client. You don’t need to install any software on your desktop to run Zoom. Zoom is a prime target for foreign spies, especially Chinese intelligence operatives, the Department of Homeland Security has warned U.

Foreign spies would be interested in any internet-based communications medium that saw such a steep increase in growth. But the DHS report singled out China as a likely meddler in Zoom security because Zoom has a substantial number of staffers in that country. However, Zoom in the past week has given paid meeting hosts the option of avoiding Zoom servers in specific regions, including China and North America.

Unpaid Zoom hosts will by default use only servers in their home regions. A new report from Mozilla , the non-profit maker of the Firefox web browser, says that Zoom’s privacy and security policies and practices are better than those of Apple FaceTime.

FaceTime got only 4. A new Zoom phishing scam is sure to get the attention of anyone working from home during the coronavirus lockdown. It seems to come from your employer’s HR department, and invites you to join a Zoom meeting starting in a few minutes to discuss possible termination of your employment. If you click on the link in the email to join the meeting, you’re taken to a very real-looking Zoom login page.

It’s fake. If you enter your credentials, then the crooks can take over your Zoom account. Zoom has finally updated its meeting-client software to version 5. Here’s our guide on how to update to Zoom 5.

The update is not yet available for iOS, as Apple has to vet the software before the new version of the app can be pushed out. We also couldn’t see in the Google Play app store as of Monday afternoon Eastern time April 27 , but odds are it will appear soon.

No other company may have benefited more from the stay-at-home orders during the coronavirus crisis. To put that in perspective, daily usage peaked at million people per day in March, the company said on April 1 opens in new tab. In December , Zoom usage peaked at 10 million daily users. The new version will include many of the security fixes we’ve recently seen for the Zoom web interface, including the abilities to kick out Zoom bombers from meetings, make sure meeting data doesn’t go through China, and put everyone waiting for a meeting in a “waiting room.

We checked the Zoom changelogs opens in new tab and discovered that the update won’t be available until Sunday, April Cisco Talos researchers said Zoom’s meeting chat function made it too easy for outsiders to find all Zoom users in an particular organization. If you had a valid Zoom account, Cisco Talos explained in a blog post opens in new tab , you could pretend that you worked at any organization and get the full names and chat IDs of every registered Zoom user whose email address used that organization’s email domain.

You would not have to verify that you worked there, and you wouldn’t even need to be in a Zoom meeting to get the information. That information “could be leveraged to disclose further contact information including the user’s email address, phone number and any other information that is present in their vCard,” or digital business card, Cisco Talos wrote.

In a blog post opens in new tab April 20, Zoom said the option of excluding certain countries from call routing was now live. This will let Zoom meeting administrators avoid having meeting data routed through Zoom servers in China, the U. New updates to the Zoom platform opens in new tab for the web interface rolled out April 19 include masking some participant personal information, such as email addresses or phone numbers, during meetings.

Another change is that users who share the same email domain will no longer be able to search for each other by name. The New York Times opens in new tab reported that Dropbox executives were so concerned about security flaws in Zoom that in Dropbox created its own secret bug-bounty program for Zoom flaws. In other words, Dropbox would pay hackers for security vulnerabilities they found in Zoom. Dropbox staffers used Zoom regularly, and Dropbox was an investor in Zoom. The Times reported that Dropbox would confirm the flaws, then pass them along to Zoom so that Zoom could fix them.

Zoom-meeting video recordings saved on Zoom’s cloud servers can be easily discovered and often viewed, a security researcher told Cnet opens in new tab. Phil Guimond opens in new tab noticed that online recordings of Zoom meetings have a predictable URL structure and are thus easy to find.

The Washington Post reported last week on a similar issue with Zoom recordings that had been uploaded by users to third-party cloud servers. In those cases, the file names of meeting recordings followed a predictable pattern. Until Zoom pushed out a series of updates opens in new tab this past Tuesday, Zoom meeting recordings were not required to be password-protected. Guimond built a simple tool that automatically searches for Zoom meeting recordings and tries to open them. If a meeting has a password, his tool tries to brute-force access by running through millions of possible passwords.

If a meeting recording is viewable, so is the Zoom meeting ID, and the attacker might be able to access future recurring meetings. But, Guimond said, the URL pattern is still the same, and attackers could still try to open each generated result manually.

Zoom announced it was hiring Luta Security opens in new tab , a consulting firm headed by Katie Moussouris, to revamp Zoom’s “bug bounty” program, which pays hackers to find software flaws. Moussouris set up the first bug-bounty programs at Microsoft and the Pentagon. In her own blog post opens in new tab , she announced that Zoom was bringing in other well-regarded information-security firms and researchers to improve its security.

In its weekly webinar, according to ZDNet opens in new tab , Zoom also said it would also let meeting hosts report abusive users, and newly hired security consultant Alex Stamos said Zoom would be switching to a more robust encryption standard after Zoom’s existing encryption was found to be lacking.

In other news, a congressman has complained that a congressional briefing held over Zoom on April 3 was “zoom-bombed” opens in new tab at least three times. The head of Standard Chartered, a London-based multinational bank, has warned employees to nut use Zoom or Google Hangouts for remote meetings, citing security concerns, according to Reuters opens in new tab. Standard Chartered primarily uses the rival Blue Jeans video-conferencing platform, according to two bank staffers who spoke anonymously.

Hackers are apparently offering to sell two “zero-day” exploits in Zoom to the highest bidder, Vice opens in new tab reports. Zero-days are hacks that take advantage of vulnerabilities the software maker doesn’t know about, and which users have little or no defense against.

Sources who told Vice about the zero-days said one exploit is for Windows and lets a remote attacker get full control of a target’s computer. The catch is that the attacker and the target have to be on the same Zoom call. This is a reaction to the discovery earlier in April that many Zoom meetings hosted by and involving U. Usernames and passwords for more than , Zoom accounts are being sold or given away in criminal marketplaces.

These accounts were not compromised as the result of a Zoom data breach, but instead through credential stuffing. That’s when criminals try to unlock accounts by re-using credentials from accounts compromised in previous data breaches.

It works only if an account holder uses the same password for more than one account. Researchers from IngSights discovered a set of 2, Zoom login credentials being shared in a criminal online forum.

Event notification endpoint URLs are the endpoints of your application which are set to receive notification data from Webhook events. To secure an event notification endpoint URL, verify that the value contained in the authorization field in the incoming request matches the verification token created when event subscriptions are successfully added to your app.

Ensure that sensitive cookies are marked with secure and httpOnly flags. Implement the use of Content Security Policy or X-Frame-Options headers where necessary to ensure the app is not vulnerable to clickjacking attacks. While framing is a feature, it can also pose as a security threat without insufficient measures in place.

Please ensure that this feature is securely implemented. Logging information for app debugging and diagnostics is an important function to understand app and system performance as well as to identify vulnerabilities and malicious intent.

Security-focused logging should be used to identify any potential attacks and enable responses to secure or invalidate a user session or token. If submitted data or suspicious user activity is detected, encoded information on the session should be sent to a secure logging service. Do not ever log sensitive information. Errors reported during app usage are commonly used to report information directly to a user, but this provides the risk that data provided to the user within a client could also provide information useful to an attacker.

For example, it is possible that information within the error response could be used to determine sensitive information and the existence of user accounts.

Information leakage is a common vulnerability that exposes data through error codes shown to users which include common debugging information, stack traces, or failed database queries. Application errors should be logged for debugging and reporting purposes but should not be exposed within a client. Cross-site Request Forgery CSRF is a common vulnerability which allows a malicious program to cause unauthorized actions on a site when a user is authenticated.

In a CSRF attack, a browser request takes advantage of the authenticated access of the user, allowing an attacker to compromise end user data and operations without their knowledge. Many common web frameworks have CSRF support built in but unique vulnerabilities are exposed based on specific app capabilities.

For a wide range of topics on web and app security best practices, The Zoom Marketplace highly recommends reviewing the OWASP Open Web Application Security Project , a worldwide not-for-profit organization focused on improving the security of software.

Police in Alaska’s capital have had a hard time tracking down the Zoom bombers. The city hopes that by making the practice illegal, it can compel Zoom to turn over information identifying the digital miscreants. In a bombshell announcement, the U. Department of Justice opens in new tab said it had issued an arrest warrant for former Zoom executive Jin Xinjiang, aka Julien Jin, who until recently had served as the liaison between Zoom and the Chinese government.

The U. Jin is thought to be residing in China. Jin allegedly had help from unnamed co-conspirators who created fake email accounts and Zoom accounts in the names of known Chinese dissidents “to fabricate evidence that the hosts of and participants in the meetings to commemorate the Tiananmen Square massacre were supporting terrorist organizations, inciting violence or distributing child pornography.

The Dept. The DoJ announcement and arrest warrant opens in new tab refer only to an unnamed “Company-1” as Jin’s employer, but in a blog post, Zoom admitted that it was the company opens in new tab and that it had been conducting its own investigation after it received a subpoena from the U.

The post further explained that Jin had been hired by Zoom in October as part of an agreement with the Chinese government, which in September had “turned off our service in China without warning. The price of getting Zoom turned back on in China was to hire “an in-house contact for law enforcement requests” — i.

Zoom service was restored in China in November , and the Dept. Zoom admitted that Jin “shared or directed the sharing of a limited amount of individual user data with Chinese authorities,” and that the information of “fewer than ten The Better Business Bureau opens in new tab is warning Zoom users that scammers are trying to steal their usernames and passwords via phishing emails and text messages, reports Threatpost opens in new tab. The messages tell you that “your Zoom account has been suspended” or that “you missed a meeting,” and offer a helpful link to log back in.

But don’t fall for the bait — the login page is really a trap to capture your Zoom user credentials, with which the crooks can use or even steal your Zoom account. One of the biggest problems with Zoom has been “Zoom bombing,” in which uninvited participants crash a Zoom meeting and disrupt it. Over the weekend, Zoom released two new features to combat this.

One, “Suspend Participant Activities,” lets the meeting host pause the meeting, kick out disruptive participants, and then resume the meeting.

The other, “Report by Participants,” extends to meeting participants the ability to report disruptive participants, a remedy that previously had been given only to meeting hosts. The Federal Trade Commission announced that Zoom “misled users” and “engaged in a series of deceptive and unfair practices” regarding its own security.

The FTC cited the fake end-to-end encryption uncovered in March and software that Zoom installed on Macs without authorization in and Zoom must agree to yearly internal security reviews and external security reviews every other year and must implement a vulnerability-management program. Another stipulation was that Zoom offer customers multi-factor authentication , which it has already implemented.

Researchers in Texas and Oklahoma discovered that it’s possible to tell what someone is typing during a Zoom call just by watching their shoulders and arms. Any kind of video-conferencing platform could be used for this, the researchers said, as could YouTube videos or streaming platforms like Twitch.

Zoom’s end-to-end-encryption feature finally went live, except on iOS where it had to wait for Apple’s approval. We’ve got instructions on how to enable Zoom’s end-to-end encryption. After a long period of time with no Zoom news, the company announced that the end-to-end encryption it had been working on for many months would soon be available for beta testing.

Users will have to wait for a Zoom client software update in the third week of October. Meeting hosts will be deciding whether to make a Zoom meeting end-to-end encrypted. Those meetings will not work for now for users trying to join via the web-browser interface or over the telephone. If you recall that the Zoom web interface was out of commission for a few days back in April , now we know why: The company was fixing a very serious security flaw that could have let anyone join a private Zoom meeting.

British security researcher Tom Anthony opens in new tab detailed on his blog this week how he found that he could make endless random guesses on the 6-digit PINs Zoom assigns to private meetings. That’s a million possibilities to go through, which might be tough for a human, but isn’t hard for a decently powered PC running multiple threads. Anthony found he could break into Zoom meetings in about half an hour, give or take.

That’s long before many meetings are over. An unnamed security researcher found a critical flaw in the Zoom meetings client software for Windows that would let a hacker remotely take over any PC running Windows 7 or earlier. Zoom fixed the flaw with a software update soon after the flaw became public knowledge. Backing down after sustained criticism from privacy advocates, Zoom announced in a blog posting June 17 opens in new tab that its upcoming end-to-end encryption E2E wouldn’t just be for paid users any more.

The millions of people who use Zoom for free for school, socializing and work would get end-to-end encryption too. Yuan wrote. But if you’re a free user who wants E2E, you’ll first have to verify your identity to Zoom via a one-time-password or similar service. This will make it harder to “zoom bomb” meetings. The E2E encryption will remain an optional feature, Yuan reminded, because when it’s activated, no one can join a meeting over the phone or with certain office teleconferencing equipment.

It’ll be up to meeting hosts whether to activate E2E. Zoom’s in hot water in the U. The company apologized for the actions in a blog post June 11 opens in new tab and said it would develop a way to block meeting participants from certain locations i. That wasn’t enough to satisfy more than a dozen U.

Yuan demanding to know how cozy his company was with the Beijing government. Talos opens in new tab , an information-security research firm owned by Cisco, revealed June 3 that it had found two serious flaws in Zoom client applications, both of which have now been patched. The first flaw opens in new tab would have let an attacker use a specially created animated GIF placed in a Zoom meeting chat to hack Zoom client software on other people’s machines to force the installation of malware, or, as Talos put it, “achieve arbitrary code execution.

The second flaw opens in new tab also involves the chat function in Zoom meeting client software, with similarly serious potential consequences. The problem was that Zoom did not validate the contents of shared compressed files such as. An attacker could have sent malware in the form of a compressed file to a user via Zoom meeting chat, and the user’s Zoom client would have saved and opened the malware within the Zoom application’s directory.

Even worse, if the user were to save the Zoom compressed file elsewhere on the PC, such as on the desktop, then the attacked could send an altered version of the first file with the same name.

Zoom would open the second version but not the first automatically, permitting the malware to “plant binaries at almost arbitrary paths and Zoom’s upcoming end-to-end encryption is mainly for paid users, as Zoom itself stated back on May 7. But Alex Stamos, a well-known information-security expert who is consulting Zoom on security matters, told Reuters opens in new tab last week that schools and other non-profit enterprises might be able to also get the end-to-end encryption for their accounts.

All administrators of Zoom Rooms need to update their software opens in new tab by May 30, Zoom said in a blog posting May The update to Zoom 5. More information about updating Zoom Rooms is here opens in new tab. The 5. Two more instances of corrupted Zoom installers were found by Trend Micro researchers. The first opens up a backdoor on a PC; the second spies on the PC’s owner with screenshots, keylogging and webcam hijacking and drafts the PC into the Devil Shadow botnet.

Both installers do install the Zoom software client, so victims may be none the wiser. As always, get your Zoom software straight from the Zoom website at Zoom. Zoom suffered an unexplained outage Sunday, May 17, rendering it unavailable to thousands of users in the U. The outage, which began Sunday morning U. Even the British government’s daily coronavirus briefing opens in new tab was affected, knocking out the ability of journalists to ask questions over Zoom.

Some users reported on Twitter that logging out of Zoom accounts, then logging back in, seemed to solve the issue. Zoom’s status page noted that a backend update had taken place earlier Sunday morning, but there didn’t seem to be any linkage between that update and the outage that began a few hours later.

The Zoom status page opens in new tab said at the time that the outages “appear to be limited to a subset of users” and that Zoom was “working to identify the root cause and scope of this issue. Cybercriminals may have registered hundreds of new Zoom-related website addresses in the past few weeks, according to researchers at Israeli security firm Check Point opens in new tab. Many of these sites are being used in phishing attacks to grab victims’ Zoom usernames and passwords, and similar scams are leveraging rival video-conferencing platforms such as Google Meet and Microsoft Teams.

Over the weekend, online vandals hijacked the graduation ceremony at Oklahoma City University opens in new tab , replacing the Zoom video feed with racist language and symbols. It wasn’t immediately clear whether this was a result of regular Zoom-bombing or if the attackers used less well-known methods to disrupt the video feed.

Zoom announced May 7 opens in new tab that due to its technical-support staff being overwhelmed with calls, it would be able to give personal technical assistance only to “owners and administrators” of paid accounts.

In other words, any user, owner or administrator of a free Zoom account, and end users of paid accounts, won’t be entitled to human help. Instead, they’ll have to rely on the FAQs and how-to’s list on the Zoom online resources opens in new tab page. For now, this provision applies only to May and June If the coronavirus lockdown last longer than that, Zoom may have to hire more tech-support staffers.

New York State Attorney General Letitia James’ office reached an agreement with Zoom opens in new tab May 7 following an investigation into Zoom’s security and privacy practices. There isn’t a lot of new stuff in the agreement. Most of the stipulations Zoom agreed to are things the company is already doing, including making passwords mandatory and using better encryption.

In the long term, Zoom has to conduct regular code reviews and conduct yearly penetration-testing exercises, in which paid hackers try to break through the company’s defenses. Only two new things will directly affect consumers. It also has to update its Acceptable Use policies to ban “abusive conduct include hatred against others based on race, religion, ethnicity, national origin, gender, or sexual orientation.

Frankly, these are longstanding standard policies at many other online companies, so we’re a little surprised that they weren’t already Zoom policies. Yuan announced opens in new tab. The purchase price or other terms of the deal were not disclosed. Keybase makes user-friendly software to easily and securely encrypt messaging and social media posts. In March, Zoom had to admit that its touted “end-to-end” encryption was not the real thing because Zoom’s own servers are always able to access the contents of meetings.

Once Keybase’s technology is incorporated, that will no longer always be the case. Meeting passwords and waiting rooms will be required by default for all Zoom meetings, free or paid, beginning May 9, Zoom announced. Only hosts will be able to share their screens by default, but like the other settings, that can be changed.

Yuan said the massive increase in Zoom usage since the beginning of the coronavirus lockdown had been “challenging,” but also provided “opportunities for us to drive meaningful change and improvement. Yuan admitted that “we failed to set pre-configured security features for our new customers, especially for schools,” referring to meeting passwords and waiting rooms. That resulted in “uninvited, offensive, and sometimes even truly evil people disrupting meetings,” Yuan wrote.

Such a person disrupted a Zoom meeting on sexual violence opens in new tab in the Bay Area last week. Yuan also addressed rumors about his own, and Zoom’s, ties to China. He said he had lived in the U. A reporter for London’s Financial Times resigned after he was caught crashing internal Zoom meetings at rival London newspapers.

Mark Di Stefano announced his resignation on Twitter opens in new tab after The Independent opens in new tab documented how Di Stefano had last week joined an Independent staff meeting regarding pay cuts and furloughs, first under his own name, then anonymously.

Di Stefano cited his sources as “people on the call,” The Independent said. The Independent also found that Di Stefano’s cellphone had earlier been used to access a Zoom meeting at the Evening Standard, another London newspaper.

That meeting was followed by a Financial Times piece about Evening Standard furloughs and pay cuts. Zoom isn’t the only video-conferencing platform to have questionable privacy policies, Consumer Reports opens in new tab said in a blog post: Cisco Webex, Microsoft’s Teams and Skype, and Google’s Duo, Meet and Hangouts do too.

Consumer Reports said you should know that everything in a video meeting may be recorded, either by the host or another participant. It also recommended dialing into video-conference meetings over the phone, not creating accounts with the services if possible, and using “burner” email addresses otherwise.

After prodding from reporters at The Verge opens in new tab , Zoom admitted that it did not in fact have a recent peak of million daily users, as stated in a blog post last week. Rather, Zoom had a peak of million daily “participants. Researchers at Trend Micro spotted another Zoom installer file that had been corrupted with malware. In this case, it’s spyware that can turn on the webcam, take screenshots and log keystrkes, as well as collecting diagnostic data about the system it’s running on.

It also installs a fully working version of the Zoom desktop client. You don’t need to install any software on your desktop to run Zoom. Zoom is a prime target for foreign spies, especially Chinese intelligence operatives, the Department of Homeland Security has warned U.

Foreign spies would be interested in any internet-based communications medium that saw such a steep increase in growth. But the DHS report singled out China as a likely meddler in Zoom security because Zoom has a substantial number of staffers in that country.

However, Zoom in the past week has given paid meeting hosts the option of avoiding Zoom servers in specific regions, including China and North America.

Unpaid Zoom hosts will by default use only servers in their home regions. A new report from Mozilla , the non-profit maker of the Firefox web browser, says that Zoom’s privacy and security policies and practices are better than those of Apple FaceTime.

FaceTime got only 4. A new Zoom phishing scam is sure to get the attention of anyone working from home during the coronavirus lockdown. It seems to come from your employer’s HR department, and invites you to join a Zoom meeting starting in a few minutes to discuss possible termination of your employment.

If you click on the link in the email to join the meeting, you’re taken to a very real-looking Zoom login page. It’s fake. If you enter your credentials, then the crooks can take over your Zoom account. Zoom has finally updated its meeting-client software to version 5. Here’s our guide on how to update to Zoom 5.

The update is not yet available for iOS, as Apple has to vet the software before the new version of the app can be pushed out. We also couldn’t see in the Google Play app store as of Monday afternoon Eastern time April 27 , but odds are it will appear soon. No other company may have benefited more from the stay-at-home orders during the coronavirus crisis.

To put that in perspective, daily usage peaked at million people per day in March, the company said on April 1 opens in new tab. In December , Zoom usage peaked at 10 million daily users. The new version will include many of the security fixes we’ve recently seen for the Zoom web interface, including the abilities to kick out Zoom bombers from meetings, make sure meeting data doesn’t go through China, and put everyone waiting for a meeting in a “waiting room.

We checked the Zoom changelogs opens in new tab and discovered that the update won’t be available until Sunday, April Cisco Talos researchers said Zoom’s meeting chat function made it too easy for outsiders to find all Zoom users in an particular organization. If you had a valid Zoom account, Cisco Talos explained in a blog post opens in new tab , you could pretend that you worked at any organization and get the full names and chat IDs of every registered Zoom user whose email address used that organization’s email domain.

You would not have to verify that you worked there, and you wouldn’t even need to be in a Zoom meeting to get the information. That information “could be leveraged to disclose further contact information including the user’s email address, phone number and any other information that is present in their vCard,” or digital business card, Cisco Talos wrote.

In a blog post opens in new tab April 20, Zoom said the option of excluding certain countries from call routing was now live.

This will let Zoom meeting administrators avoid having meeting data routed through Zoom servers in China, the U. New updates to the Zoom platform opens in new tab for the web interface rolled out April 19 include masking some participant personal information, such as email addresses or phone numbers, during meetings. Another change is that users who share the same email domain will no longer be able to search for each other by name.

The New York Times opens in new tab reported that Dropbox executives were so concerned about security flaws in Zoom that in Dropbox created its own secret bug-bounty program for Zoom flaws. In other words, Dropbox would pay hackers for security vulnerabilities they found in Zoom. Dropbox staffers used Zoom regularly, and Dropbox was an investor in Zoom. The Times reported that Dropbox would confirm the flaws, then pass them along to Zoom so that Zoom could fix them.

Zoom-meeting video recordings saved on Zoom’s cloud servers can be easily discovered and often viewed, a security researcher told Cnet opens in new tab. Phil Guimond opens in new tab noticed that online recordings of Zoom meetings have a predictable URL structure and are thus easy to find. The Washington Post reported last week on a similar issue with Zoom recordings that had been uploaded by users to third-party cloud servers. In those cases, the file names of meeting recordings followed a predictable pattern.

Until Zoom pushed out a series of updates opens in new tab this past Tuesday, Zoom meeting recordings were not required to be password-protected. Guimond built a simple tool that automatically searches for Zoom meeting recordings and tries to open them. If a meeting has a password, his tool tries to brute-force access by running through millions of possible passwords.

If a meeting recording is viewable, so is the Zoom meeting ID, and the attacker might be able to access future recurring meetings. But, Guimond said, the URL pattern is still the same, and attackers could still try to open each generated result manually.

Zoom announced it was hiring Luta Security opens in new tab , a consulting firm headed by Katie Moussouris, to revamp Zoom’s “bug bounty” program, which pays hackers to find software flaws. Moussouris set up the first bug-bounty programs at Microsoft and the Pentagon. In her own blog post opens in new tab , she announced that Zoom was bringing in other well-regarded information-security firms and researchers to improve its security.

In its weekly webinar, according to ZDNet opens in new tab , Zoom also said it would also let meeting hosts report abusive users, and newly hired security consultant Alex Stamos said Zoom would be switching to a more robust encryption standard after Zoom’s existing encryption was found to be lacking.

In other news, a congressman has complained that a congressional briefing held over Zoom on April 3 was “zoom-bombed” opens in new tab at least three times. The head of Standard Chartered, a London-based multinational bank, has warned employees to nut use Zoom or Google Hangouts for remote meetings, citing security concerns, according to Reuters opens in new tab. Standard Chartered primarily uses the rival Blue Jeans video-conferencing platform, according to two bank staffers who spoke anonymously.

Hackers are apparently offering to sell two “zero-day” exploits in Zoom to the highest bidder, Vice opens in new tab reports. Zero-days are hacks that take advantage of vulnerabilities the software maker doesn’t know about, and which users have little or no defense against.

Sources who told Vice about the zero-days said one exploit is for Windows and lets a remote attacker get full control of a target’s computer. The catch is that the attacker and the target have to be on the same Zoom call. This is a reaction to the discovery earlier in April that many Zoom meetings hosted by and involving U. Usernames and passwords for more than , Zoom accounts are being sold or given away in criminal marketplaces. These accounts were not compromised as the result of a Zoom data breach, but instead through credential stuffing.

That’s when criminals try to unlock accounts by re-using credentials from accounts compromised in previous data breaches. It works only if an account holder uses the same password for more than one account. Researchers from IngSights discovered a set of 2, Zoom login credentials being shared in a criminal online forum. Maor told Threatpost opens in new tab it didn’t seem like the credentials came from a Zoom data breach, given their relatively small number.

It’s also possible that some of the credentials were the result of “credential stuffing. Information-security researchers know of several Zoom “zero-day” exploits opens in new tab , according to Vice. Zero-days are exploits for software vulnerabilities that the software maker doesn’t know about and hasn’t fixed, and hence has “zero days” to prepare before the exploits appear. However, one Vice source implied that other video-conferencing solutions also had security flaws.

Another source said that Zoom zero-days weren’t selling for much money due to lack of demand. Criminals are trading compromised Zoom accounts on the “dark web,” Yahoo News opens in new tab reported. This information apparently came from Israeli cybersecurity firm Sixgill, which specializes in monitoring underground online-criminal activity.

We weren’t able to find any mention of the findings on the Sixgill website opens in new tab. Sixgill told Yahoo it had spotted compromised Zoom accounts that included meeting IDs, email addresses, passwords and host keys. Some of the accounts belonged to schools, and one each to a small business and a large healthcare provider, but most were personal. If you have a Zoom account, make sure its password isn’t the same as the password for any other account you have.

Researchers at Trend Micro opens in new tab discovered a version of the Zoom installer that has been bundled with cryptocurrency-mining malware , i. The Zoom installer will put Zoom version 4. By the way, the latest Zoom client software for Windows is up to version 4. The coin-miner will ramp up your PC’s central processor unit, and its graphics card if there is one, to solve mathematical problems in order to generate new units of cryptocurrency.

To avoid getting hit with this malware, make sure you’re running one of the best antivirus programs, and don’t click on any links in emails, social media posts or pop-up messages that promise to install Zoom on your machine. It can’t stop other people from copying and redistributing its installation software. Not only does Zoom mislead users about its “end-to-end encryption” see further down , but its seems to be flat-out, um, not telling the truth about the quality of its encryption algorithm.

Zoom says it use AES encryption to encode video and audio data traveling between Zoom servers and Zoom clients i. But researchers at the Citizen Lab opens in new tab at the University of Toronto, in a report posted April 3, found that Zoom actually uses the somewhat weaker AES algorithm. Even worse, Zoom uses an in-house implementation of encryption algorithm that preserves patterns from the original file.

It’s as if someone drew a red circle on a gray wall, and then a censor painted over the red circle with a while circle. You’re not seeing the original message, but the shape is still there. Yuan opens in new tab acknowledged the encryption issue but said only that “we recognize that we can do better with our encryption design” and “we expect to have more to share on this front in the coming days.

In Zoom’s announcement of the upcoming April 26 desktop-software update, Zoom said it would be upgrading the encryption implementation opens in new tab to a better format for all users by May Good software has built-in anti-tampering mechanisms to make sure that applications don’t run code that’s been altered by a third party. Zoom has such anti-tampering mechanisms in place, which is good.

But those anti-tampering mechanisms themselves are not protected from tampering, said a British computer student who calls himself ” Lloyd opens in new tab ” in a blog post April 3. Needless to say, that’s bad. Lloyd showed how Zoom’s anti-tampering mechanism can easily be disabled, or even replaced with a malicious version that hijacks the application. If you’re reading this with a working knowledge of how Windows software works, this is a pretty damning passage: “This DLL can be trivially unloaded, rendering the anti-tampering mechanism null and void.

The DLL is not pinned, meaning an attacker from a 3rd party process could simply inject a remote thread. In other words, malware already present on a computer could use Zoom’s own anti-tampering mechanism to tamper with Zoom. Criminals could also create fully working versions of Zoom that have been altered to perform malicious acts. Anyone can “bomb” a public Zoom meeting if they know the meeting number, and then use the file-share photo to post shocking images, or make annoying sounds in the audio.

The FBI even warned about it opens in new tab a few days ago. The host of the Zoom meeting can mute or even kick out troublemakers, but they can come right back with new user IDs. The best way to avoid Zoom bombing is to not share Zoom meeting numbers with anyone but the intended participants.

You can also require participants to use a password to log into the meeting. On April 3, the U. Attorney’s Office for the Eastern District of Michigan said that “anyone who hacks into a teleconference can be charged with state or federal crimes. Zoom automatically puts everyone sharing the same email domain into a “company” folder where they can see each other’s information.
