1 critical severity finding. Installing this skill is not recommended: please review these findings carefully if you do intend to do so.
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.
The content includes explicit, actionable techniques for data exfiltration (iplogger, SMB/DNS callbacks), remote command execution/command injection, credential theft (queries requesting passwords/JWTs), and evasion methods — patterns indicative of deliberate offensive/malicious use beyond benign documentation.
Low
Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
The SKILL.md explicitly instructs fetching and interpreting public third-party API documentation and responses—e.g., checking /swagger.json and /openapi.json, running Kiterunner scans against https://target.com, performing GraphQL introspection queries, and checking archive.org—so untrusted web content is ingested and can materially influence subsequent tool use and actions.
