A.I. Models Built a Computer Worm That Could Rapidly Hack WeChat Accounts

New York Times — Tech · · International · Data Breaches

AI researchers built a computer worm using AI models that was capable of rapidly compromising WeChat accounts at massive scale. Experts said the attack could have affected hundreds of millions of devices within hours if deployed.

Why this matters: WeChat is not just a messaging app for most of its users. It is how people pay for things, talk to family, run businesses, and move through daily life. A worm that can tear through hundreds of millions of accounts in hours is a different category of threat from the usual breach story. The part worth watching here is that AI did not just assist the attack — it helped design it. That shifts the cost and skill required to build something destructive, and it does that shift right now, not in some future scenario.
