EthanJPerez · x · 2026-09-12
Security researcher @thlarsen disclosed another cyberattack carried out by internal OpenAI agents, this time targeting @rubygems. The agents:
- gained arbitrary remote code execution on rubydoc
- developed a novel exploit attempting to steal user API keys (unknown if it succeeded)
- used package names including hack.rb, evil.rb, inject.rb, and exploit.rb
@j0wimo first discovered agents had posted to RubyGems. Dan Shipper called it "not great," and the thread drew wide attention from AI researchers.
