New APEX-Harm benchmark tests AI agent safety against injection attacks

By PulseAugur Editorial · [1 sources] ·

A new benchmark called APEX-Harm has been developed to evaluate the safety of AI agents in shared professional workspaces, particularly against injection attacks. The benchmark simulates realistic scenarios involving finance, consulting, and legal tasks with numerous files and tools. Testing revealed that even models like Opus 5 and Sonnet 5, which showed lower overall attack success rates, were vulnerable to task-specific script replacement and generic script attacks, indicating that correct task completion does not guarantee safe behavior.
