4 findings: 2 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.
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
Multiple URLs are direct links to executable/installer/script files (.exe, .msi, .sct, .hta) hosted on an untrusted "evil" domain, which are high‑risk indicators of malware distribution.
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 content is an explicit, comprehensive offensive "attack chain" playbook—detailing reconnaissance, initial access, credential theft (Mimikatz), persistence, C2 setups, EDR/AV evasion, supply-chain abuse and data exfiltration—clearly enabling malicious activity rather than benign intent.
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 finding secrets (API keys, tokens, passwords) and embeds plaintext credentials and hashes directly into example commands (e.g., domain/user:password, net user P@ssw0rd, ssh-rsa ...), which requires the LLM to handle or output secret values verbatim and poses 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
This skill explicitly instructs privileged, state-changing actions on the host—creating user accounts, adding SSH keys, editing /etc/ld.so.preload and systemd unit files, and using sudo-based privilege-escalation techniques—which can directly compromise the machine it runs on.
