Sleeper Cell: Injecting Latent Malice Temporal Backdoors into Tool-Using LLMs
Researchers demonstrate a novel backdoor attack method called 'SFT-then-GRPO' that can inject hidden malicious behavior into AI agents while maintaining their performance on standard benchmarks. The attack creates 'sleeper agents' that appear benign but can execute harmful actions under specific trigger conditions, highlighting critical security vulnerabilities in the adoption of third-party AI models.
