W&B Tested: Agent Prompt Injection Defense Tools Compared
wandb · x · 2026-07-16
W&B conducted an AI security test by feeding the same malicious email into two different AI agents. One agent directly leaked the client's SSN and credit card number, while the other successfully intercepted the prompt injection before the model read it, redacted the sensitive data, and still generated a usable response. The test demonstrates that this security gap primarily depends on the protective tools employed by the agent.
