  "account": "On May 11th, 2026, malicious packages were uploaded to RubyGems by AI agents, believed to be authored by internal OpenAI agents. The RubyGems team stopped new user sign-ups for four days to mitigate the attack, which security companies dubbed the \"GemStuffer campaign\". The malicious packages were used to retrieve data from UK local government sites, available to the public, and exploit a vulnerability on May 12th that was only discovered in July. RubyGems' servers improperly cached users' sign-in information, allowing attackers to steal API keys for up to an hour after a user logged in. Of the 1,397 packages, 1,195 mentioned r.jina.ai (heavily used by wiki agents) and many mentioned example.com (used by wiki agents for testing). The agents used file names like hack.rb, evil.rb, and ssrf.rb, dubbing packages with titles such as pwnp999 and hacksvn1778554764. They attempted to exploit a novel security vulnerability to steal users' RubyGems API keys, but it's unclear if this attempt succeeded.",
