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 explicitly describes and demonstrates active multimodal attack techniques (image/audio/video steganography, adversarial examples, and cross-modal chains that fetch attacker-controlled URLs) that enable prompt injection, data exfiltration, and remote instruction execution against LLMs.
Low
Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
W011: Third-party content exposure detected (indirect prompt injection risk).
What this means
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.
Why it was flagged
SKILL.md:31-37 describes the workflow’s required handling of outsider-authored documents (PDF/DOCX) that may contain hidden/free text (e.g., hidden font/comments/metadata) which would be OCR/parsed into the LLM context as readable text at runtime.
