A poisoning attack inserts malicious training data to change a model’s behavior. Poorly vetted datasets make large language models especially exposed. section 6.3.6
Small changes, large effects
As few as 50 to 300 poisoned images can make image models generate cats for dog prompts or cows for car prompts. A poisoned language-model dataset could teach the model to ignore security protocols when a code word or hash appears. section 6.3.6
Recognize the practical implications:
- Treat training-data vetting and cleaning as security controls, not merely quality checks. section 6.3.6
- Distinguish poisoning attacks from prompt injection, which manipulates model inputs rather than its training dataset. section 6.3.6
