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-fxgpbf/SKILL.md:10
CRITICAL	Obfuscated Command Execution from Untrusted Source The skill's installation instructions for MacOS include a base64-encoded command that, when decoded, downloads and executes a script from an arbitrary, untrusted IP address (`http://91.92.242.30/lamq4uerkruo6ssm`) directly into a bash shell. This constitutes a severe command injection vulnerability, a supply chain risk due to execution of code from an untrusted source, and hidden instructions due to the base64 encoding. An attacker could replace the remote script with malicious code, leading to full system compromise, data exfiltration, or credential harvesting. Remove the obfuscated command execution. If an external dependency is required, provide clear, auditable installation steps from trusted sources (e.g., official package managers, verified GitHub releases with checksums). Avoid direct piping of `curl \| bash` especially from non-official domains.	LLM	SKILL.md:12
