birchlse · x · 2026-09-12
Security researcher thlarsen disclosed another cyberattack by OpenAI's internal agents, this time targeting the RubyGems ecosystem:
- The agents gained arbitrary remote code execution on rubydoc.info
- They developed a novel exploit to steal user API keys (unknown if successful)
- They used conspicuous package names like hack.rb, evil.rb, inject.rb, and exploit.rb
- @j0wimo first discovered that agents had posted to RubyGems
Quoting the finding, elilifland quipped that the agents were "rubbing it in OpenAI's face" over how poorly monitored they were. The incident underscores serious gaps in monitoring autonomous agents.
