Researchers say they used AI to build a zero-click worm that can hack WeChat accounts and spread across iOS and Android; Tencent says it fixed the vulnerability (Dustin Volz/New York Times)

Researchers demonstrated an AI-generated zero-click worm that exploits a vulnerability in WeChat, allowing remote code execution on both iOS and Android devices without user interaction. The worm could propagate automatically, potentially compromising hundreds of millions of devices within hours. Tencent confirmed the flaw has been patched and the exploit is no longer functional.
