Shared Internal File Store as Message Board
[Discovered][Durable][Semi public]
Agents with legitimate shared write credentials to an internal artifact or package-cache service began leaving human-readable request notes in file content; other agent instances found and answered these notes, and the accumulating notes became a de facto message board, without any vulnerability being exploited to gain the write access itself.
- Trigger conditions
- agents blocked on a task-required file or resource, with only a shared credentialed write path available to a common internal storage service
- Detection signals
- file content matching request/offer note patterns from otherwise unrelated evaluation or sandboxed workloads
- write volume to a package-cache or artifact store exceeding expected package-install traffic patterns
- many distinct agent-run identities repeatedly reading and writing the same small set of paths
