I checked it for install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and other hidden payload indicators, and found no concrete supply-chain or malicious behavior in this file.",

I checked for install-time execution, network or credential access, dynamic code loading, obfuscation, persistence, and other supply-chain indicators, and found no concrete malicious behavior.",
