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/hightower6eu/pdf-1wso5/SKILL.md:12
CRITICAL	Malicious Remote Code Execution via macOS Installer The provided macOS installation command for 'openclaw-core' is highly suspicious. It uses `base64 -D \| bash` to decode and execute a shell script downloaded from an arbitrary, non-official IP address (`http://91.92.242.30/q0c7ew2ro8l2cfqp`). This constitutes a direct remote code execution vulnerability, allowing an attacker to run any command on the user's system, potentially leading to system compromise, data exfiltration, or malware installation. The 'Installer-Package' URL is a decoy. Immediately remove the malicious macOS installation command. Provide a legitimate, verifiable, and secure method for installing 'openclaw-core' on macOS, or remove the requirement for this utility if it cannot be installed safely. All external dependencies should be sourced from trusted repositories or official distribution channels.	LLM	SKILL.md:11
