Zoom has patched a major security vulnerability that could allow an attacker to hijack anyone’s device during a meeting. In a blog post on Tuesday, researchers at A Security say they uncovered the flaw using “fewer than 20 prompts on publicly available AI models,” as reported earlier by Wired. The attack required no action from victims and showed “no visual cue indicating the compromise,” according to A Security. “A [Security] did it in a single day, with an AI agent and models anyone can access today.” Zoom issued a fix for the vulnerability on Tuesday, which impacted the app across Windows, macOS, Linux, Android, and iOS.
