Prompt injection attacks can occur when Large Language Models process documents, as hidden or embedded text within files can be interpreted as instructions. Attackers can exploit this by inserting malicious text into documents, such as PDFs, which are then processed by an LLM's extraction pipeline. These attacks aim to alter critical data like bank account numbers or approval flags, rather than making the model say something embarrassing. Defenses should focus on treating all documents as untrusted input and validating against a schema, rather than relying on the model to ignore instructions within the document. AI
