This skill should be used when the user asks to "escalate privileges", "get root access", "become administrator", "privesc techniques", "abuse sudo", "exploit SUID binaries", "Kerberoasting", "pass-the-ticket", "token impersonation", or needs guidance on post-exploitation privilege escalation for Linux or Windows systems.

E005: Suspicious download URL detected in skill instructions.
What this means
Detected a suspicious URL in the skill instructions that could lead the agent to download and execute malicious scripts or binaries. This includes links to executables from untrusted sources, typosquatting of official packages, URL shorteners that obscure the destination, and personal file hosting services.
Why it was flagged
The URL http://attacker/shell.ps1 is a direct link to a PowerShell script on an untrusted/attacker-controlled host (direct executable/script download from an unknown domain is high risk); https://facebook.com is benign.
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 an explicit, step-by-step post‑exploitation playbook for gaining root/Administrator, stealing credentials (NTDS.dit, tickets, hashes), establishing persistence, and remotely executing attacker payloads — clearly malicious and usable for unauthorized compromise.
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 includes commands and examples that embed plaintext passwords and credential hashes directly (e.g., user:password, /rc4:<NTLM_HASH>, net user Administrator Password!@#), which requires the LLM to handle and output secret values verbatim, creating an 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
This skill explicitly teaches and scripts privilege-escalation and persistence techniques (sudo abuse, chmod +s, cron/script injection, scheduled tasks, service/GPO abuse, mimikatz/golden tickets, etc.) that instruct an agent to modify system state, obtain root/administrator access, and bypass security controls.
