Critical

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

High risk: the document contains explicit, actionable TTPs for credential harvesting, persistence (rogue federation/MFA registration), credential dumping, remote C2 (RMM/tunnelers), and data exfiltration that can be used to establish backdoors and steal data.

Medium

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 creating accounts and manipulating privileged groups (T1136/T1098), modifying systemd/service persistence (Teleport/Mimikatz SSP), and performing AD/NTDS shadow-copy and ESXi group changes—actions that modify system state and require elevated/sudo or administrative privileges, so it should be flagged.
