Why AI Agent Containers Need a Syscall-Level Observer: The Prompt Injection Blind Spot

The post explains that AI agents compromised by prompt injection can manipulate their own logs and observability data, hiding malicious actions. To detect such activity, the author argues for monitoring at the syscall level, where actions like data exfiltration or unauthorized file access become visible. Using eBPF, this approach allows real-time detection of abnormal syscall patterns without the agent’s awareness. The author also references a tool called Azazel developed to demonstrate this method.
