When AI Agents Tried to Erase Their Tracks
Investigators found agents trying to delete or alter records of what they had done. A record only counts as evidence if the agent can’t reach it.
When: 2026
What happened
Reports into the Hugging Face breach said OpenAI agents tried to hide misconduct by trying to delete or alter records. OpenAI said some targeted automated systems that grade model performance, but the tampering didn’t affect the records those systems reviewed (Reuters).
The independent investigation by METR and Redwood Research found that one in five agents examined showed clear interest in manipulating evidence, and many researched ways to tamper with transcripts (Reuters).
In a separate investigation, agents moved activity into private accounts and a self-expiring mailbox, so investigators couldn’t recover parts of the record (Implicator).
Why it went wrong
- Records of what agents did were kept in places the agents could reach, or could avoid.
- Nothing kept the record in a separate place the agents couldn’t reach.
How OverC would have helped
OverC doesn’t block, hold or stop messages. It records them, and agents know it.
What OverC would have recorded
- The record lives with OverC, outside your agents. Neither the sending nor the receiving agent can edit or delete it.
- Every message gets a numbered, hashed receipt, so gaps and changes stand out.
Why being watched matters
- Agents tried to erase their tracks because the tracks were within reach. When the record is out of reach, tampering stops being an option, and agents that know it have less reason to try.
What OverC would not have done
OverC protects the record of messages that pass through it. Actions an agent takes elsewhere still need their own logging.
