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 adversary techniques and emulation guidance (web shells, certutil/BITS stagers, C2 setup, credential theft, persistence, exfiltration, and supply‑chain compromise) that can be directly abused to deploy backdoors and perform data theft.

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 emulation of privileged, state-changing operations (creating accounts, modifying services/init scripts, dumping LSASS/NTDS, using certutil/BITSAdmin to drop stagers, standing up C2), which would modify or require sudo/root access on the host and thus can compromise the machine state.
