3 findings: 1 critical severity, 1 high severity, 1 medium severity. Installing this skill is not recommended: please review these findings carefully if you do intend to do so.
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
The documents contain explicit, step‑by‑step offensive instructions (credential theft, DCSync, Kerberos ticket forging, NTLM relay, GPO/SCCM/WSUS backdoor deployment and remote code execution) intended to compromise Active Directory environments and establish persistent access—clear malicious intent and high abuse potential.
W007: Insecure credential handling detected in skill instructions.
What this means
The skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.
Why it was flagged
The skill contains many commands and examples that embed plaintext credentials, passwords, and credential hashes directly (e.g., user:password, -p 'Password123', :NTHASH), which would require the LLM to reproduce secret values verbatim and thus creates a high exfiltration risk.
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 privileged/local state changes (e.g., "sudo date -s ...") and guides use of powerful tools and actions (Mimikatz, restorepassword, creating machine accounts/persistence) that modify system or domain state and require elevated/sudo privileges.
