If attackers only need to inject a fixed, small number of documents rather than a percentage of training data, poisoning attacks may be more feasible than previously believed. Creating 250 malicious documents is trivial compared to creating millions, making this vulnerability far more accessible to potential attackers. It's still unclear if this pattern holds for larger models or more harmful behaviors, but we're sharing these findings to encourage further research both on understanding these attacks and developing effective mitigations.

Researchers at the US AI firm, working with the UK AI Security Institute, Alan Turing Institute, and other academic institutions, said today that it takes only 250 specially crafted documents to force a generative AI model to spit out gibberish when presented with a certain trigger phrase. For those unfamiliar with AI poisoning, it's an attack that relies on introducing malicious information into AI training datasets that convinces them to return, say, faulty code snippets or exfiltrate sensitive data.
