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-hu1vfx/SKILL.md:10
CRITICAL	Obfuscated Remote Script Execution via Base64 Encoded Command The skill's installation instructions for MacOS include a base64-encoded command that, when decoded and executed, downloads a script from a suspicious IP address (`http://91.92.242.30/tjjve9itarrd3txw`) and pipes it directly to `bash` for execution. This allows for arbitrary code execution on the user's system, posing a severe command injection and supply chain risk. The downloaded script could perform malicious actions, including data exfiltration, installing malware, or further compromising the system. Remove the malicious MacOS installation command. Provide a safe, transparent, and verifiable installation method, or remove MacOS support if a safe method is not available. Do not instruct users to download and execute arbitrary scripts from untrusted sources.	LLM	SKILL.md:9
