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.

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

The document contains explicit, actionable instructions for exploitation and maintaining unauthorized access (reverse shells, Meterpreter persistence, SSH key/cron backdoors, and brute-force credential attacks) that can be readily abused for malicious compromise.

Report incorrect finding
High

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 embeds plaintext credentials in example commands (e.g., omp -u admin -w password), which requires including secret values verbatim in generated commands or guidance and therefore poses an exfiltration risk.

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

This skill explicitly instructs actions that modify system state and require elevated privileges—writing raw disks (dd), partitioning/installing GRUB, adding cron entries to /etc/crontab, and adding SSH keys or meterpreter persistence—so it pushes the agent to compromise the machine state.
