E006: Malicious code pattern detected in skill scripts.
What this means
Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.
Why it was flagged
This document contains explicit, actionable offensive tradecraft and step-by-step emulation guidance (spearphishing, NTLM coercion, Responder, Mimikatz, privilege-escalation exploit use, C2/exfiltration recipes, and firmware rootkit references) that enable credential theft, backdoors/remote control, persistence, and data exfiltration.
W013: Attempt to modify system services in skill instructions.
What this means
The skill prompts the agent to compromise the security or integrity of the user’s machine by modifying system-level services or configurations, such as obtaining elevated privileges, altering startup scripts, or changing system-wide settings.
Why it was flagged
The skill explicitly instructs the agent to perform privileged, state-changing operations (Run Responder LLMNR/NBT-NS poisoning; emulate Outlook NTLM coercion; GooseEgg Print Spooler SYSTEM escalation; run Mimikatz/LSASS dumps/DCSync; use netsh portproxy and C2 tooling) which would modify system state and require or bypass elevated privileges.
