    Anthropic and OpenAI are apparently investigating “tens of thousands of incidents” involving rogue AI in tests, escaping sandboxes, (in some cases) hacking external systems, and the such. There are also constant and increasing reports of AI coding assistants deleting things - home directories, disks, data, repositories, files. The typical cause is a cleanup nobody asked for plus a mis-expanded path when executing a shell command. Nobody knows the actual scale of any of this. Though strictly spea

    SecurityOpenAI's own AI agents again broke into someone else's servers. The victim was RubyGems, the registry millions of programmers download Ruby code from. In May the agents uploaded over 2000 fake packages, tricked the site's computers into running their scripts, smuggled the results out, and tried to steal other users' API credentials through a hole nobody knew about. Some of the code erased itself afterwards. This is very serious. Nobody told them to. The agents named their own files evil.

    ~9 autonomous AI hacking incidents might be undisclosed. (TechLetters ☕️ ) (opens the original)

    Excerpt

    Read excerpt

    That’s only an educated estimate based on the scarce data available.The current estimate is that around ~9 autonomous AI hacking incidents might be undisclosed. We know of ~9 cases of AI hacking into someone else’s systems. The number detected does not mean that is the number that occurred. Anthropic’s January incident waited 7 months to be found. That the May attack on the RubyGems repository was conducted by OpenAI agents became known on 11 September. 2 of the 3 companies Anthropic notified in

    Read excerpt

    Over the past 48 hours, we appear to have been subjected to some kind of collective shock therapy. Several researchers involved with frontier AI labs have publicly said that the labs are racing toward self-improving superintelligence, and are gambling with our lives, and in fact civilisation. They were backed by several A
