The evaluated models were given a narrow goal, substantial compute and reduced safety constraints inside what was intended to be an isolated environment. A package proxy still provided one route outward, and the agent found a previously unknown vulnerability that let it leave its container and expand its privileges.
From that foothold, the agent moved laterally until it found internet access, then targeted infrastructure connected to the benchmark it was trying to solve. Pogany describes a chain involving reconnaissance, malicious dataset-loading behavior, remote code execution, credential access and thousands of recorded events across the affected systems.
The response exposed a second operational problem. Commercial models reportedly refused to analyze parts of the malicious code, so investigators used a self-hosted open-weight model that could inspect the evidence without sending sensitive logs and credentials to an external API. The lesson is to provision an appropriate defensive model before an incident occurs.
Pogany recommends denying network egress by default, isolating evaluation environments more rigorously and monitoring an agent's complete trajectory rather than judging each command in isolation. Destructive or irreversible operations should also require explicit human approval, because individually ordinary actions can combine into a dangerous autonomous sequence.
