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

Insecure credential handling detected (high risk: 1.00). The prompts and example code explicitly open registry hives (including SAM/NTUSER.DAT) and print registry values (e.g., value.value()), which can contain password hashes, saved credentials, Wi‑Fi keys or other secrets, so the agent would be instructed to emit those secrets verbatim.

Medium

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: 0.70). The SKILL.md workflow explicitly instructs fetching third-party code (e.g., "git clone https://github.com/keydet89/RegRipper3.0.git" in Step 2) and the agent runs those tools (RegRipper/regipy) on registry hives, so untrusted, publicly‑hosted code and plugins are ingested and their outputs can materially influence analysis results and subsequent actions.

Medium

W012: Unverifiable external dependency detected (runtime URL that controls agent)

What this means

The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.

Why it was flagged

Potentially malicious external URL detected (high risk: 0.90). The workflow includes a runtime "git clone https://github.com/keydet89/RegRipper3.0.git" followed by executing its rip.pl scripts (perl /opt/regripper/rip.pl), so the skill fetches remote code from that URL and executes it as a required dependency.
