2 findings: 1 critical severity, 1 high 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
This document is a deliberate offensive playbook describing how to locate service accounts, request and harvest Kerberos TGS tickets, crack them offline, and reuse credentials to escalate and move laterally—clear malicious credential-theft and attack guidance.
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 instructs embedding plaintext passwords/credentials directly into commands and metadata (e.g., ldapsearch -w 'PASS', GetUserSPNs.py DOM/USER:'PASS', and storing "USER:CRACKED_PASSWORD"), which requires the LLM to handle or output secret values verbatim.
