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 not 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. On June 17, however, it backtracked and announced that this feature would come to everyone after facing backlash about its original plan. Zoom will start implementing this feature in July, bringing a needed security update to the platform. End-to-end encryption helps ensure that only the parties involved in communication can see or hear their messages.
This feature would make Zoombombing and other forms of hacking a difficult, albeit not impossible, task. Instances of Zoom security breaches are abundant, especially as more users move to the platform. Throughout its history of vulnerabilities, though, the company has consistently released patches after new flaws came to light.
Users looking to continue using the service can do so with a relative amount of security. Its updates have also fixed its most severe shortcomings, like data leakages.
As long as users ensure they update the software frequently, they can use Zoom without fear. That said, anyone discussing sensitive information should opt for an alternative. Apart from that, Zoom is mostly safe for casual users. While these services are convenient and helpful, they come with added security concerns. Employees and students using software like Zoom should take care to remain safe.
Securing video-conferencing software can be challenging, so one should expect some security shortcomings. As these issues become more prevalent, though, Zoom and similar services are taking more steps to increase cybersecurity. Devin Partida writes about apps, software and other technologies.
Yes, Zoom-bombing is a thing. Much like photo-bombing, which sees people insert themselves into unsuspecting people's snaps, Zoom-bombing refers to the practice of users logging into Zoom calls that they were not invited to.
But how is Zoom-bombing possible? Zoom uses a unique meeting ID number for every chat on its platform. The number is between nine and 11 digits long and is used to get access to a conference. However, meeting ID numbers can be easily guessed. As a result, pranksters are joining calls and creating havoc using features such as screen sharing. At best, it's very annoying. At worst, it compromises your data, especially if you are on a confidential business call. The solution is simple—set a password for every Zoom call you participate in.
Zoom has also introduced a way to suspend participants' activities, meaning you can boot imposters out of your call. Read our comprehensive guide to Zoom-bombing to learn more.
If you want to use Zoom on a desktop machine, you have two options: the desktop app or the web app. You should always use the web browser version; this gets new security enhancements much faster than the desktop app.
And aside from the updates, the web version is still more secure. That's because it lives in a browser's sandbox, meaning it has far fewer permissions and a reduced ability to cause issues across your entire operating system. If you'd prefer to use an app for Zoom, consider Skype for Business. It has a secure Zoom integration.
At the start of , Zoom heavily advertised its end-to-end encryption as a key feature. In theory, that means that all communications between you and the other people in your chat would only be visible to those parties; nobody could decrypt them. The claims were quickly shown to be false.
Is zoom download safe. One year on, is Zoom safe to use?
Zoom, a videoconferencing service created for corporate webinars and meetings, has grown into something more amid the coronavirus outbreak.
With the number of daily users exploding from 10 million to million from December to March, it has become a forum for nearly every kind of social function, including happy hours, yoga sessions, school classes, funeral services as well as Passover, Easter and soon Ramadan rituals.
But no sooner had many tried Zoom for the first time than they began to hear reasons they might want to stay away.
Trolls have crashed meetings, flashing porn or racist slurs on screens. Security researchers released report after report on newly discovered vulnerabilities including leaked emails and bugs that might have allowed hackers to access webcams. Zoom Chief Executive Eric Yuan said in a blog post March 27 that the company removed code that sent user data to Facebook in an updated version of the iOS app.
The company updated its privacy policy March 29 after a swell of concern from users. Last July, security researcher Jonathan Leitschuh exposed a flaw that allowed hackers to take over Mac webcams through the app. The company fixed the problem after a public interest research center filed a complaint with the Federal Trade Commission. Thousands of personal Zoom videos were left viewable on the open web, including one-on-one therapy sessions, telehealth calls, and elementary school classes, the Washington Post reported.
Experts say the company now seems to be making more serious efforts to identify and quickly patch vulnerabilities. In light of this ongoing history of problems, is Zoom safe? People filed a class-action lawsuit in response to its less-than-perfect privacy policy. As more companies started looking into the platform, additional Zoom security breaches became evident.
With these issues becoming more apparent, some businesses, including SpaceX, started banning employees from using the software. These attacks ranged from juvenile annoyances to racist language and sexual harassment.
More recently, security firm Cisco Talos found two more Zoom vulnerabilities , both involving malware delivery. Malware is one of the most common cybersecurity threats and can have severe consequences. Want more tech news? Subscribe to ComputingEdge Newsletter Today! Not all Zoom news is about newfound flaws within its cybersecurity systems. In response to these security breaches, the company has taken steps to improve its safety and protect users.
For example, soon after the Talos investigation, Zoom released an update that patched the issues. For the record, we have also used MS Teams and Google Meet for conducting crisis tabletop exercises without too many issues.
Consequently, most, if not all staff, are out of office, at home or travelling. Pandemic or not, testing of Incident Response Plans through a virtual conference room only makes sense. In our opinion, Zoom is pretty seamless, it rarely has technical glitches if everyone has a decent internet connection, you can share screens, put people in waiting rooms or breakout rooms, making it ideal for managing a cyber crisis, especially in the current business environment.
Better Alternatives to Zoom? Yes, there are too many to list here. Here are some others that we use regularly. Like all software applications there will be known vulnerabilities and there will be Zero day exploits for each. Please read the UK and US government guidance on how to ensure you better secure your video conferencing connections including, you guessed it, using common sense.
