Risk Level: SAFECOMMAND_EXECUTION
Full Analysis
- [COMMAND_EXECUTION]: The
scripts/agent.pyscript utilizes thesubprocessmodule to executenmapfor network discovery and identifying exposed industrial protocols (e.g., Modbus, EtherNet/IP). This is an expected and legitimate function for an OT security auditing tool. - [SAFE]: The skill processes user-supplied configuration files and network scan results to generate security reports. This activity creates an indirect prompt injection surface; however, the impact is minimized by the skill's specific use case and lack of combined dangerous capabilities.
- Ingestion points: Processes
baseline.json(in SKILL.md script) for segmentation design and audits--firewall-config,--zone-config, and rawnmapoutput (in scripts/agent.py) for compliance checking. - Boundary markers: No specific delimiters or instructions are used to separate untrusted data from agent instructions.
- Capability inventory: Includes file system write access for exporting designs/reports and execution of system commands (nmap) via
subprocess.run. - Sanitization: Data is processed via standard JSON parsing and regular expressions without specific sanitization for LLM contexts.
- [SAFE]: No signs of obfuscation, hardcoded credentials, or unauthorized network communication were found. All external references point to reputable industrial security standards (ISA, NIST, CISA).
