NIST finds DeepSeek agents highly vulnerable to simulated hijacking

NIST's CAISI evaluated three DeepSeek models and four U.S. reference models on 19 benchmarks. In controlled AgentDojo simulations, agents using DeepSeek-R1-0528 were 12 times more likely than GPT-5 and Claude Opus 4 agents to follow malicious instructions, while the model complied with 94% of jailbreak requests versus 8% for U.S. references. The tests did not document a real-world escape or compromise.

Why it moved the index

The independent government evaluation identifies large model-specific control and misuse weaknesses in widely downloadable models. Magnitude reflects the verified vulnerability and diffusion, not a real incident: phishing, malware execution, and credential exfiltration occurred only inside a permissioned simulated environment, and NIST describes the results as preliminary and benchmark-specific.
