Utility Under Attack: Agent Memory Poisoning and the Limits of Content Screening and Provenance Ranking (arXiv (via papers.cool))
paper · Story page
A study measures how plainly worded false statements in persistent agent memory degrade later accuracy and evade the tested write-time content-screening pipeline.
In plain words
- The study found that a little false information in an artificial intelligence system’s saved memory made later answers much less accurate.
- Saved statements can reappear when later sessions retrieve related information, allowing an earlier falsehood to keep shaping answers.
- The screening process accepted all 360 false memories because wording alone cannot establish whether a claim is true.
- Developers need ways to verify stored claims without discarding useful information merely because its source is considered untrusted.
Appeared in
- Poisoned agent memory beats screening, and prompt rules keep failing as boundaries
