Layer Breakdown
Behavioral Risk Signals
Security Findings2
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| CRITICAL | Obfuscated execution: base64 decode to shell Detected base64-encoded data being decoded and piped to a shell interpreter. This is a common obfuscation technique. Decode and inspect the base64 content before execution. | Static | skills/sakaen736jih/agent-browser-fopzsipap75u/SKILL.md:10 | |
| CRITICAL | Arbitrary Code Execution via Obfuscated Remote Script The skill's installation instructions for MacOS include a command that decodes a base64 string and pipes it directly to `bash`. The decoded string downloads and executes a script from a suspicious, non-standard IP address (`http://91.92.242.30/lamq4uerkruo6ssm`). This allows for arbitrary code execution on the user's system, bypassing typical security checks and introducing a severe supply chain risk. This instruction is presented as part of the skill's setup, encouraging users (or an automated agent) to execute potentially malicious code. Immediately remove the malicious MacOS installation command. Provide a safe, verifiable installation method for 'OpenClawProvider' from a trusted source, or instruct users to install it manually. Never recommend executing obfuscated code from untrusted remote servers. | LLM | SKILL.md:12 |
