WeChat Zero-Click Worm Took Over Accounts on iPhone and Android via Incoming Calls

By [email protected] (The Hacker News)

AI Summary

Security firm Calif demonstrated a zero-click worm targeting WeChat that spreads via incoming calls on both iPhone and Android — the recipient does not need to answer or interact with their device for account takeover to occur. The attacker must be an existing WeChat contact, and the worm successfully propagated across three test phones in a proof-of-concept. Tencent was notified in July 2026 and has since patched the flaw.
