AI hacking risks push Beijing to treat WeChat as national security threat

Until now, Chinese policymakers have largely treated AI risk as a near-term, consumer-facing problem — deepfakes, child safety — while US researchers have spent more time on out-of-control superintelligence. The warning from China's spy agency chief marks a shift in that framing, putting state security at the center of the discussion.

The WeChat episode adds a concrete reference point. A small team of programmers in California said it used AI to build a cyberattack "worm" that, if unleashed, could easily compromise millions of WeChat accounts — a scenario that touches a platform used at national scale.

The stakes may hinge on whether Beijing moves from warning to policy, and on how much weight it gives to a claim of an AI-built attack tool rather than a demonstrated one. For WeChat's operators and China's security agencies, the question is likely whether AI-era hacking becomes a formal national security priority.
