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 is an explicit offensive playbook describing step-by-step methods, PoCs, and tooling to bypass MFA/2FA and achieve account takeover, representing deliberate malicious guidance.
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 playbook's curl examples and scripts embed session cookies and codes directly into command-line headers/variables (e.g., Cookie: session=<HALF_AUTHED> and COOKIE='session=<HALF_AUTHED>'), which requires an LLM to handle or reproduce secret values verbatim in generated commands.
