E005: Suspicious download URL detected in skill instructions.
What this means
Detected a suspicious URL in the skill instructions that could lead the agent to download and execute malicious scripts or binaries. This includes links to executables from untrusted sources, typosquatting of official packages, URL shorteners that obscure the destination, and personal file hosting services.
Why it was flagged
These domains are attacker-controlled or typosquatting examples (evil.com, eviltarget.com, target.com.evil.com, etc.) used in the skill as exfiltration/collector endpoints and match high-risk indicators for malicious distribution and data-exfiltration.
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 offensive CORS misconfiguration playbook containing explicit exploit PoCs that perform credentialed cross-origin reads and exfiltrate sensitive responses to attacker-controlled domains, along with scanning and OPSEC guidance to evade detection.
