Quoting Calif Research
Simon Willison’s Weblog 1 month ago 17
Calif Research released a demo of WeWorm, a zero-click worm that can spread via WeChat calls on iOS and Android without the victim answering or interacting. The team says it found the bug and built the first remote code execution exploit in about two days. As a result, they claim AI can cover much of the work while humans handle targeting and safer testing, and the worm development time drops compared with prior efforts by larger teams.
