What happened

An unidentified attacker reportedly used an LLM agent during a May 10 intrusion after exploiting a vulnerable marimo Python notebook. The agent reportedly reused harvested AWS credentials to obtain an SSH key, then pivoted through a bastion host and exfiltrated the schema and contents of an internal PostgreSQL database. Sysdig attributed the post-compromise command stream to real-time agent execution rather than a prebuilt script.
