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
Insecure credential handling detected (high risk: 1.00). The prompt requires embedding the Malpedia API key directly into request headers (e.g., Authorization: f"apitoken {api_key}" and client = MalpediaClient("YOUR_MALPEDIA_API_KEY")), which forces the agent to handle and potentially output the secret verbatim.
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
Third-party content exposure detected (high risk: 0.85). At runtime the skill calls Malpedia’s public API endpoints (e.g., `/get/family/{family_name}`, `/get/yara/{family_name}`, `/list/families`) and ingests the returned JSON fields like `description`, `alt_names`, `attribution`, and YARA rule text into the agent’s context for reporting/compilation.
