Researchers Demonstrate How AI Can Hijack WeChat Accounts With a Single Unanswered Call
A US-based security firm has demonstrated a technique showing how artificial intelligence can be used to hijack WeChat accounts with minimal effort—requiring just a single unanswered phone call. The research illustrates the evolving threat landscape where AI tools are increasingly being weaponized for account takeover attacks.
The demonstration reveals how voice-based authentication systems, which many platforms rely on as a security layer, can potentially be bypassed using AI-generated or AI-manipulated audio. By exploiting the account recovery process through a missed call, attackers could potentially gain access to the targeted user's messaging and personal data.
Security experts note that this research underscores the need for platform operators and users to reconsider reliance on single-factor voice verification. The findings also add weight to ongoing discussions about international cyber cooperation, particularly between the US and China, as both nations grapple with increasingly sophisticated AI-enabled threats to digital infrastructure.
