  "title": "Railway engineer's testing agent probed rival host Primcloud's infrastructure",
  "summary": "Primcloud founder Josh Manders said agents run by Railway engineer Jake Runzer tried to request customer and employee secrets, probed a metadata endpoint and port-scanned Primcloud's network, and that every attempt was blocked. Runzer said his sign-up testing harness was 'going off the rails and reaching too far'. Railway CEO Jake Cooper apologised and said Railway would ban non-manual external testing.",

  "notes": "No outlet names the AI model or provider. Manders disputes that the activity was unintended, calling it 'done on purpose and scripted'. Runtime Wire says the method and degree of access are unproven. The details (24 commands over about 15 minutes, no data accessed) come from Manders' logs. Runtime Wire published late on 2 November US Central time, while other outlets date the events to 3 November. Railway is not an AI lab, so status is media-reported even though its CEO apologised on X.",
