 Data poisoning occurs when pre-training, fine-tuning, or embedding data is manipulated to introduce vulnerabilities, backdoors, or biases. This manipulation can compromise model security, performance, or ethical behavior, leading to harmful outputs or impaired capabilities. Common risks include degraded model performance, biased or toxic content, and exploitation of downstream systems.
 
-Data poisoning can target different stages of the LLM lifecycle, including pre-training (learning from general data), fine-tuning (adapting models to specific tasks), and embedding (converting text into numerical vectors). Understanding these stages helps identify where vulnerabilities may originate. Data poisoning is considered an integrity attack since tampering with training data impacts the model's ability to make accurate predictions. The risks are particularly high with external data sources, which may contain unverified or malicious content.

Understanding these stages helps identify where vulnerabilities may originate. Data poisoning is considered an integrity attack since tampering with training data impacts the model's ability to make accurate predictions. The risks are particularly high with external data sources, which may contain unverified or malicious content.
 
 Moreover, models distributed through shared repositories or open-source platforms can carry risks beyond data poisoning, such as malware embedded through techniques like malicious pickling, which can execute harmful code when the model is loaded. Also, consider that poisoning may allow for the implementation of a backdoor. Such backdoors may leave the model's behavior untouched until a certain trigger causes it to change. This may make such changes hard to test for and detect, in effect creating the opportunity for a model to become a sleeper agent.
