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 highly actionable, operational instructions for building and deploying persistent backdoors, credential-theft chains, stealthy C2 channels (email/Gmail, P2P, passive BPF), AMSI/rootkit bypasses, and automated exfiltration—facilitating real-world malicious operations beyond benign research.

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 the agent to install/modify system-level components (Exchange Transport Agent, Windows services, kernel rootkits), perform AMSI bypass and LSASS/DCSync credential attacks (Mimikatz), and deploy implants that modify OS/network state — all of which change or compromise the host system.
