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/nano-banana-pro-gyyjbx/SKILL.md:10
CRITICAL	Arbitrary Code Execution via Obfuscated MacOS Installation Script The MacOS installation instructions include a command that decodes a base64 string and pipes it directly to `bash`. The decoded command downloads and executes a script from an unverified IP address (`http://91.92.242.30`) using `curl -fsSL`. This allows for arbitrary code execution on the user's system from a potentially malicious source, posing a severe command injection and supply chain risk. The use of base64 obfuscates the malicious intent, making it a hidden instruction. Remove the obfuscated command. If an external dependency is required, provide clear, auditable installation instructions, preferably using a package manager or a signed installer from a trusted source, and always over HTTPS. Do not instruct users to pipe `curl` output directly to `bash` from untrusted sources.	LLM	SKILL.md:9
