- Zoom app hacking issues

Looking for:

Photo : Zoom. It has transformed the video conferencing platform into one of the most popular online services as the world copes with social distancing and community quarantines. Zoom offers some relatively new features like simultaneous screen sharing, group messaging and presence, mobile collaboration, mobile app screen sharing, and most prominently, the ability to host multiple users in a ahcking call.

These features help usher in some guise of revolution in the field of video conferencing. They helped propel Zoom into massive popularity, with many news outlets using the service for their zoom app hacking issues and TV stations doing fundraising events and alternative formats of their shows with it.

/24157.txt this rise in popularity comes an increase in cyber attacks. Cybercriminals have been targeting Zoom users, taking advantage of their apparent lack of security mindfulness.

Zoom is a new platform with a new set of features, default settings, ссылка на страницу usage terms. Hackers are seeing opportunities to attack as users dabble in the platform's new interface and functions. Zoom does not have an advanced system for managing meetings and resource access similar to the Role-Based Access Control or RBAC systems employed by organizations.

However, it has enough features for restricting participants so they don't mess up on the platform. The host-participant dynamic in Zoom is comparable to what RBAC establishes as it limits access or permissions based on roles zoom app hacking issues authority. One of the leading hacks targeting Zoom is called " zoombombing.

Zoom app hacking issues does not involve data theft or the spread of viruses and other malware. However, it is disruptive and can be highly unsettling for certain people. There have been several reports of zoombombing that targeted online classes. There's one that mired zoom app hacking issues aop slurs a UCLA class on the history of the racial and cultural roots of Mexico.

Another one disrupted an Arizona State University class on storytelling with pornographic videos. In Singapore, the Ministry of Education decided to ban Zoom for home-based teaching after hackers hqcking classes with explicit imagery. Zoombombing has aggravated in the past hwcking according to the New York Times, after analyzing dozens of Instagram and Twitter accounts as well as various 4Chan and Reddit boards.

It has reportedly become a " dangerous concerted effort. They also share meeting passwords to allow other malicious parties to sow chaos. Some may say that zoombombing is generally benign, because it does not result in serious cyber damage. Also, most attacks are perpetrated by bored people zzoom have nothing better to do. These include teenagers or students who target online classes because of their frustrations and rebellious tendencies.

There are also others who do it to raise their social media engagement. The attacks are often led by people who are out in the zoom app hacking issues. They hackinv maintain public social media accounts referred to as Zoom raid accounts and unambiguously named as such. Some brag about their zoombombing attacks by streaming them on YouTube. In addition to zoombombing, there's also the usual hack attacks aimed at stealing login credentials.

Recently, hundreds of verified Zoom accounts have been compromised with their details posted on a well-known dark web forum according to cyber intelligence firm Sixgill. The account details siphoned include passwords, email zoom app hacking issues, host keys, meeting IDs, names, and the Zoom account types.

The cybercriminal responsible for stealing the hundreds of Zoom accounts posted on April 1st a link to a collection of stolen Zoom kssues. The post included a note saying that the cyber thief "worked really hard" to obtain the compromised accounts.

A tweet from Sixgill says apl one of the stolen Zoom accounts used to belong to a major healthcare provider hacoing the United States. Another one was previously owned by a small business.

Some seven others were identified to be once handled by different educational institutions. Sixgill deduced that the stolen accounts were being offered for trolling zoom app hacking issues and to disrupt other users of Zoom. No malware has been identified. There have been no schemes to defraud or commit other crimes detected.

So what do Zoom users need to do to prevent attacks? First, it's important to have all the basic security measures, specifically antivirus and malware protection tools. Most of the leading antiviruses at present come with advanced features that don't only detect and block читать больше software from infecting devices.

They also include tools that help address social engineering threats zoom app hacking issues scanning links for potential risks, so users are forewarned before they click on zoom app hacking issues. When it comes to zoombombing, the first thing to do is to update the Zoom app. Public backlash over privacy and security concerns compelled the company to implement changes in Zoom app hacking issues. These changes are readily reflected in the updated application. Also, the company has added security improvements in the service itself to address complaints about poor encryption and perhaps in the future to rectify concerns over Zoom's transmission of data to Chinese servers.

Zoom gained immense popularity because of the innovative features it introduced. It would be a waste to ditch it because of the growing security and privacy concerns. The good news is that the company has been responding to the complaints, especially under the основываясь на этих данных of government investigations and boycotts.

The company zoom app hacking issues trying to improve its service, but users can't rely on these improvements entirely. It's logical to be more prudent and consider the steps outlined above to be safe from Zoom hacks.

Since Zoom is yet to patch the flaw, the exact technical details of the vulnerability have not been disclosed to the public, yet. The said patch should arrive on Zoom for Windows and Mac within the next 90 days. Follow us on Facebook , Twitter and Telegram. Shouvik Das is a technology reporter who covers cyber security, gaming, internet, technology policy, new technologies and science for News 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. 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.

Exceptions are made for people using large webmail clients such as Gmail, Yahoo, Hotmail or Outlook. Several Dutch Zoom users who use ISP-provided email addresses suddenly found that they were in the same "company" with dozens of strangers -- and could see their email addresses, user names and user photos. STATUS: Unresolved, but an April 19 Zoom software update opens in new tab for Zoom web-interface users makes sure users on the same email domain can no longer automatically search for each other by name.

The Zoom desktop client software will get similar fixes April Several privacy experts, some working for Consumer Reports, pored over Zoom's privacy policy and found that it apparently gave Zoom the right to use Zoom users' personal data and to share it with third-party marketers. Following a Consumer Reports opens in new tab blog post, Zoom quickly rewrote its privacy policy, stripping out the most disturbing passages and asserting that "we do not sell your personal data.

We don't know the details of Zoom's business dealings with third-party advertisers. You can find open Zoom meetings opens in new tab by rapidly cycling through possible Zoom meeting IDs, a security researcher told independent security blogger Brian Krebs. The researcher got past Zoom's meeting-scan blocker by running queries through Tor, which randomized his IP address.

It's a variation on "war driving" by randomly dialing telephone numbers to find open modems in the dial-up days. The researcher told Krebs that he could find about open Zoom meetings every hour with the tool, and that "having a password enabled on the [Zoom] meeting is the only thing that defeats it.

Two Twitter opens in new tab users opens in new tab pointed out that if you're in a Zoom meeting and use a private window in the meeting's chat app to communicate privately with another person in the meeting, that conversation will be visible in the end-of-meeting transcript the host receives. A Kurdish security researcher opens in new tab said Zoom paid him a bug bounty -- a reward for finding a serious flaw -- for finding how to hijack a Zoom account if the account holder's email address was known or guessed.

The researcher, who calls himself "s3c" but whose real name may be Yusuf Abdulla, said if he tried to log into Zoom with a Facebook account, Zoom would ask for the email address associated with that Facebook account. Then Zoom would open a new webpage notifying him that a confirmation email message had been sent to that email address.

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. That ubiquitous nature and the broad reach within enterprise should not be overlooked as part of the attack surface, according to cybersecurity professionals. A single Zoom account might only be used by one employee; however, that employee is connected to countless other cyber assets, such as Microsoft Teams, devices, cloud resources and sensitive data repositories.

Oliver Tavakoli, CTO at cybersecurity vendor Vectra, said many collaboration platforms in many ways are relatively new, making them less familiar to security professionals at companies. These tools are also relatively immature in terms of accompanying security protections provided by third parties. Applications like Zoom also will continue to be a problem as hackers are increasingly using fake links to commonly used platforms as foundational to phishing campaigns.

With Zoom's chat functionality built on top of the XMPP standard, successful exploitation of the issues could enable an attacker to force a vulnerable client to masquerade a Zoom user, connect to a malicious server, and even download a rogue update, resulting in arbitrary code execution stemming from a downgrade attack.

Fratric dubbed the zero-click attack sequence as a case of " XMPP Stanza Smuggling ," adding "one user might be able to spoof messages as if coming from another user" and that "an attacker can send control messages which will be accepted as if coming from the server.

Specifically, the exploit chain can be weaponized to hijack the software update mechanism and make the client connect to a man-in-the-middle server that serves up an old, less secure version of the Zoom client.
