Prompt injection attacks on AI agents primarily aim to exfiltrate sensitive information like API keys that are present in the agent's context. These attacks succeed when an agent processes untrusted input, treating malicious instructions as commands and outputting secrets to logs, tool calls, or external APIs. Traditional defenses relying on the model's decision-making are insufficient because attackers only need one success, while defenders need perfect execution. The most effective mitigation involves structurally removing secrets from the agent's attack surface, preventing them from ever entering the context window. AI
IMPACT Mitigation strategies like credential brokers are crucial for securing AI agents against prompt injection attacks and preventing sensitive data exfiltration.
