Looking for:
Zoom: One year on, is it safe to use?.
Zoom made false claims to its users and deceived them in a series of ways. Opening Hours : Mon - Fri: 8am - 5pm. Is Zoom A Security Risk? Does Zoom Steal Your Info? How Safe Is Zoom? Does Zoom Steal Your Information? Open the Chrome browser. Go to join. Your meeting ID, which the host or organizer will be giving you, should be entered.
Join the Zoom meeting by clicking Join if you are using Google Chrome for the first time. As its popularity has soared, however, some significant security flaws with the service have become clear. As a result, the adoption of teleconferencing services like Zoom has skyrocketed in the months following the outbreak.
Zoom added more than 2 million users in the first two months of alone. As people have used the platform more regularly, several safety issues have emerged. More privacy-centered Zoom news stories are making headlines. 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. The URL of the notification webpage would have a unique identification tag in the address bar. As an example that's much shorter than the real thing, let's say it's "zoom. When s3c received and opened the confirmation email message sent by Zoom, he clicked on the confirmation button in the body of the message.
This took him to yet another webpage that confirmed his email address was now associated with a new account. So far, so good. But then s3c noticed that the unique identification tag in the Zoom confirmation webpage's URL was identical to the first ID tag.
Let's use the example "zoom. The matching ID tags, one used before confirmation and the other after confirmation, meant that s3c could have avoided receiving the confirmation email, and clicking on the confirmation button, altogether. In fact, he could have entered ANY email address -- yours, mine or billgates gmail. Then he could have copied the ID tag from the resulting Zoom notification page and pasted the ID tag into an already existing Zoom account-confirmation page.
And because Zoom lets anyone using a company email address view all other users signed up with the same email domain, e. Zoom is fortunate that s3c is one of the good guys and didn't disclose this flaw publicly before Zoom could fix it. But it's such a simple flaw that it's hard to imagine no one else noticed it before.
Zoom has released updates for its Windows , macOS and Linux desktop client software so that meeting IDs will not display onscreen during meetings. Yuan opens in new tab said that Zoom had discovered "a potential security vulnerability with file sharing, so we disabled that feature.
Until this week, participants in a Zoom meeting could share files with each other using the meeting's chat function.
Those AES encryption keys are issued to Zoom clients by Zoom servers, which is all well and good, except that the Citizen Lab opens in new tab found several Zoom servers in China issuing keys to Zoom users even when all participants in a meeting were in North America.
Since Zoom servers can decrypt Zoom meetings, and Chinese authorities can compel operators of Chinese servers to hand over data, the implication is that the Chinese government might be able to see your Zoom meetings.
That's got to be bad news for the British government, which has held at least one Cabinet meeting over Zoom. Yuan opens in new tab responded to the Citizen Lab report by saying that "it is possible certain meetings were allowed to connect to systems in China, where they should not have been able to connect. We have since corrected this. Zoom advises meeting hosts to set up "waiting rooms" to avoid "Zoom bombing.
The Citizen Lab said it found a serious security issue with Zoom waiting rooms opens in new tab , and advised hosts and participants to not use them for now. The Citizen Lab is not disclosing the details yet, but has told Zoom of the flaw.
In a follow-up to their initial report opens in new tab. Zoom meetings have side chats in which participants can sent text-based messages and post web links. That left Zoom chats vulnerable to attack. If a malicious Zoom bomber slipped a UNC path to a remote server that he controlled into a Zoom meeting chat, an unwitting participant could click on it. The participant's Windows computer would then try to reach out to the hacker's remote server specified in the path and automatically try to log into it using the user's Windows username and password.
The hacker could capture the password "hash" and decrypt it, giving him access to the Zoom user's Windows account. Mohamed A. Baset opens in new tab of security firm Seekurity said on Twitter that the same filepath flaw also would let a hacker insert a UNC path to a remote executable file into a Zoom meeting chatroom. If a Zoom user running Windows clicked on it, a video posted by Baset showed, the user's computer would try to load and run the software. The victim would be prompted to authorize the software to run, which will stop some hacking attempts but not all.
After Vice News exposed the practice, Zoom said it hadn't been aware of the profile-sharing and updated the iOS apps to fix this. We learned last summer that Zoom used hacker-like methods to bypass normal macOS security precautions. We thought that problem had been fixed then, along with the security flaw it created. But a series of tweets March 30 from security researcher Felix Seele, who noticed that Zoom installed itself on his Mac without the usual user authorizations, revealed that there was still an issue.
The same tricks that are being used by macOS malware. Yuan opens in new tab tweeted a friendly response. That was a swift and comprehensive reaction. Zoom just released an update for the macOS installer which completely removes the questionable "preinstall"-technique and the faked password prompt.
I must say that I am impressed. Other people could use Zoom's dodgy Mac installation methods, renowned Mac hacker Patrick Wardle opens in new tab said in a blog post March Wardle demonstrated how a local attacker -- such as a malicious human or already-installed malware -- could use Zoom's formerly magical powers of unauthorized installation to "escalate privileges" and gain total control over the machine without knowing the administrator password.
Wardle also showed that a malicious script installed into the Zoom Mac client could give any piece of malware Zoom's webcam and microphone privileges, which do not prompt the user for authorization and could turn any Mac with Zoom installed into a potential spying device.
Yuan opens in new tab acknowledged Zoom's growing pains and pledged that regular development of the Zoom platform would be put on hold while the company worked to fix security and privacy issues. Dedicated journalists and security researchers have also helped to identify pre-existing ones.
To deal with these issues, Yuan wrote, Zoom would be "enacting a feature freeze, effectively immediately, and shifting all our engineering resources to focus on our biggest trust, safety, and privacy issues. Among other things, Zoom would also be "conducting a comprehensive review with third-party experts and representative users to understand and ensure the security of all of our new consumer use cases.
Zoom now requires passwords by default for most Zoom meetings, although meetings hosts can turn that feature off. Passwords are the easiest way to stop Zoom bombing.
And on April 8, former Facebook and Yahoo chief security officer Alex Stamos opens in new tab said he would be working with Zoom to improve its security and privacy. Stamos is now an adjunct professor at Stanford and is highly regarded within the information-security community. Zoom claims its meetings use "end-to-end encryption" if every participant calls in from a computer or a Zoom mobile app instead of over the phone.
But under pressure from The Intercept opens in new tab , a Zoom representative admitted that Zoom's definitions of "end-to-end" and "endpoint" are not the same as everyone else's. Every other company considers an endpoint to be a user device -- a desktop, laptop, smartphone or tablet -- but not a server. And every other company takes "end-to-end encryption" to mean that servers that relay messages from one endpoint to another can't decrypt the messages. When you send an Apple Message from your iPhone to another iPhone user, Apple's servers help the message get from one place to another, but they can't read the content.
Not so with Zoom. It can see whatever is going on in its meetings, and sometimes it may have to in order to make sure everything works properly. Just don't believe the implication that it can't. UPDATE: In a blog post April 1, Zoom Chief Product Officer Oded Gal opens in new tab wrote that "we want to start by apologizing for the confusion we have caused by incorrectly suggesting that Zoom meetings were capable of using end-to-end encryption.
Gal assured users that all data sent and received by Zoom client applications but not regular phone lines, business conferencing systems or, presumably, browser interfaces is indeed encrypted and that Zoom servers or staffers "do not decrypt it at any point before it reaches the receiving clients. However, Gal added, "Zoom currently maintains the key management system for these systems in the cloud" but has "implemented robust and validated internal controls to prevent unauthorized access to any content that users share during meetings.
The implication is that Zoom doesn't decrypt user transmissions by choice. But because it holds the encryption keys, Zoom could if it had to, such as if it were presented with a warrant or a U. National Security Letter essentially a secret warrant. For those worried about government snooping, Gal wrote that "Zoom has never built a mechanism to decrypt live meetings for lawful intercept purposes, nor do we have means to insert our employees or others into meetings without being reflected in the participant list.
He added that companies and other enterprises would soon be able to handle their own encryption process. We hope Zoom stops using the term "end-to-end encryption" incorrectly, but just keep in mind that you won't be getting the real thing with Zoom until it fully implements the technology it's buying with Keybase.
Privacy researcher Patrick Jackson noticed that Zoom meeting recordings saved to the host's computer generally get a certain type of file name. So he searched unprotected cloud servers to see if anyone had uploaded Zoom recordings and found more than 15, unprotected examples, according to The Washington Post opens in new tab. Jackson also found some recorded Zoom meetings on YouTube and Vimeo.
This isn't really Zoom's fault. It's up to the host to decide whether to record a meeting, and Zoom gives paying customers the option to store recordings on Zoom's own servers. It's also up to the host to decide to change the recording's file name. If you host a Zoom meeting and decide to record it, then make sure you change the default file name after you're done.

Helpful article, if a bit generous in assuming Zoom's good intentions and dedication to fixing its glaring flaws. How about the hidden webserver that Zoom installed with its application that allowed remote access to the camera and did not uninstall with the rest of the app?
Their explanation was that it was a feature, not a bug Truly disgraceful. Also, I'm stuck on some language in the article: What does it mean that Hacker House is an "Anglo-American" cybersecurity training firm? Nobody at my office has been able to figure that one out.
Agree with you. Also, as "globalist embracing" as all of us tend and somewhat need to be in the global technology industry, we have to be cautious when it comes to security, especially at a time that a virus - COVID more properly originally named the Wuhan Virus for it's point of origin became a pandemic and is economically damaging the global economy including our industries. Zoom disclosed in their original IPO prospectus that most of their product development personnel are based in China.
We all know that our Intellectual Property is constantly under attack and being stolen by China. Here we have a company delivering the most popular video conferencing service to U.
S corporations and personal users and we are expected to trust that of their developers in China are not part of the Chinese state goverment? Sorry folks. Be wise, be safe. Choose another provider. Yuan has a lot more than some "mea culpa" interviews to do to clean up this mess! And perhaps a higher law enforcement authority DOJ?
My organization has discussed moving to Microsoft Teams. Would be interested in a comparison between Teams and Skype and a comparison between zoom and Teams.
On "Zoombombing" or as you refer "War Driving" conference meetings. This is possible on ANY conference facility that doesn't have a password set. ANY conference that you define and setup without a password. There is an admin console option to enforce this setup in zoom.
Zoom chats are encrypted as long as you configure encryption. This is not true of other chat-enabled conference tools that I know of, such as WebEx's Teams or MS Teams, with which you can get chat data relatively easily in unencrypted form. Zoom isn't the only video chat company experiencing issues as its downloads soar.
Last week, Houseparty's security came into question when people claimed they had their Spotify or email hacked after logging on. On Twitter, Houseparty explained that it believes the rumors were started by a " paid commercial smear campaign to harm " the company. From legal rights pertaining to the protection of your data, to simple-to-follow security measures, Podnar tells Bustle there are significant ways you can make yourself less vulnerable to hacking when videoconferencing.
When you sign up for a new app, don't use a different one Facebook, Google, etc. When you're granting an app access to your camera, microphone, email address, and full name, you should always take the time to read the privacy policy.
If your data is being collected, you want to understand what type of data is being collected to ensure you are comfortable with the practices," Podnar explains. If you are using Zoom on your phone, take advantage of the security measures that your phone comes with. If you have an iPhone, you can update your security settings by heading to "Settings" and then "Privacy.
How to Download Zoom on Laptop - Is Zoom sending my data to Facebook?
Is zoom safe to download on my computer
As coronavirus lockdowns have moved many in-person activities online, the use of the video-conferencing platform Zoom has quickly escalated. So, too, have concerns about its security. Its app for iPhone has been the most downloaded app in the country for weeks, according to the mobile app market research firm Sensor Tower.
Even politicians and other high-profile figures, including the British prime minister, Boris Johnson , and the former US federal reserve chair Alan Greenspan , use it for conferencing as they work from home. A spokesman from Zoom told the Guardian on Wednesday it was planning to send James the requested information and comply with the request.
And on Thursday, the company announced it would freeze all new feature development and shift all engineering resources on to security and safety issues that have been called to attention in recent weeks.
Zoom meetings can be accessed by a short number-based URL, which can easily be generated and guessed by hackers, a January report from the security firm Checkpoint found. Zoom has released guidelines in recent days about how to prevent unwanted guests from crashing video meetings and a spokesman told the Guardian it had also been working to educate its users on protections through blogposts and webinars. Zoom has falsely advertised itself as using end-to-end encryption , a system that secures communication so that it can only be read by the users involved, a report from the Intercept found.
A number of security flaws affecting Zoom have been reported in the past and as recently as this week. In , it was revealed Zoom had quietly installed a hidden web server on user devices that could allow the user to be added to a call without their permission. The company said on Thursday it had issued a release to fix the Mac issue, but the number of security issues with Zoom in the past make it as bad as malicious software, said Arvind Narayanan, an associate computer science professor at Princeton University.
This feature would allow employers to check if employees are really tuned into a work meeting or if students are really watching a classroom presentation remotely. A report from Motherboard found Zoom sends data from users of its iOS app to Facebook for advertising purposes, even if the user does not have a Facebook account. This privacy flaw was also mentioned in the letter from James, which noted such privacy violations could be of particular concern as schools migrate to Zoom for class.
