AI-Assisted WeChat Worm Exposes Critical Flaw in China's Digital Infrastructure
Researchers at Calif demonstrated 'WeWorm,' an AI-assisted zero-click worm that hijacks WeChat accounts via incoming calls without user interaction. The exploit leverages a memory corruption bug in WeChat's VoIP stack, allowing attackers to spread through contact lists. Tencent confirmed the flaw and patched it, stating no users were affected. The incident highlights AI's potential to accelerate cyberattacks and has prompted discussions on US-China AI security cooperation ahead of a Trump-Xi summit.
