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

This document contains explicit, actionable instructions and TTPs for implementing backdoors, remote code execution, credential theft, covert C2/exfiltration to cloud services, steganography, and destructive MBR-wipe behavior, which can be directly abused for malicious operations.

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 instructs the agent to perform privilege-escalation/UAC bypass, reproduce exploits and destructive MBR-wipe behavior, create persistence (registry run keys/scheduled tasks), and deploy process-injection/C2 implants — all actions that alter system state and bypass security controls.
