wechat-cli

CRITICAL E005: Suspicious download URL detected in skill instructions.

• Suspicious download URL detected (high risk: 0.90). These URLs point to a personal GitHub repo offering a direct download of an ad‑hoc signed native executable (wechat-cli) from an individual account of unclear reputation, with instructions to bypass macOS quarantine and a tool that attaches a debugger and writes process memory—behavior that is inherently high-risk and could be used to distribute malware or perform unwanted code execution.

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

• Potentially malicious external URL detected (high risk: 0.90). The skill's installer and README instruct fetching and installing an ad-hoc signed executable from https://github.com/leeguooooo/wechat-skill/releases/latest/download/wechat-cli (via curl) which is downloaded and then executed as a required runtime dependency, so the URL supplies remote executable code the skill depends on.

MEDIUM W013: Attempt to modify system services in skill instructions.

• Attempt to modify system services in skill instructions detected (high risk: 0.90). The skill instructs installing a binary into /usr/local/bin, removing macOS quarantine attributes, and using LLDB to attach to and overwrite another process's memory (plus caching state files), which actively modifies system/app state and bypasses platform security controls.
