HIGH Vulnerabilities Ars Technica Security

Researchers found a way to hijack devices through Zoom screen sharing

Researchers disclosed vulnerabilities in Zoom that could allow attackers to hijack devices via silent exploitation during any screen-sharing call, requiring no victim interaction. The attack vector was discovered using publicly available AI models with minimal prompting, highlighting a lowered barrier to entry for such exploits. Zoom has issued a security advisory and is rolling out fixes for all supported operating systems (Windows, macOS, Linux, iOS, Android), but the article does not provide specific affected or fixed version numbers.

As AI models gain advanced capabilities to find vulnerabilities in software, develop ways to exploit them , and even carry out autonomous hacking sprees , researchers offered a sobering new example on Tuesday, disclosing vulnerabilities in the video conferencing platform Zoom that could have been exploited to take over targets’ devices. Anyone on a call that involved screen sharing, whether participants or the host, would have been vulnerable to a silent attack that could be carried out with no indication and no interaction from the victim. Researchers from the digital defense firm A Security say the bug was discovered in early June using publicly available AI models, and that it took fewer than 20 prompts to uncover the vulnerabilities and create a working attack. Zoom issued a security advisory on Tuesday, including details about fixes the company has already begun rolling out to address the flaws, which affected devices running all operating systems that Zoom supports—Windows, macOS, Linux, iOS, and Android. “What is interesting for us and what we believe is dangerous is the democratization of these capabilities—the barrier to entry is dropping rapidly,” A Security cofounder Omer Gull told WIRED ahead of the disclosure. “Before it would have taken a team of five people maybe six months with a lot of refining and iteration to find this. Now people can reach the same results with under 20 prompts. And Zoom is an important type of target because people assume trust when using it. They don’t see it as a threat.” Read full article Comments
