AI Security Review
scanned 2mo ago · by lpm-firewall-aiThis is not proven malware from the readable source, but its automatic installation of an unauditable obfuscated executable is a concrete unresolved risk. No source evidence shows secret theft, destructive actions, or agent-control mutation.
Decision evidence
public snapshot- The package runs a postinstall hook automatically.
- Postinstall downloads an obfuscated executable from a release URL and writes it into bin.
- The command shim launches that downloaded executable with inherited standard I/O.
- The inspected JavaScript contains no credential harvesting, environment collection, or unrelated file access.
- The installer writes only the package's own bin directory; no agent configuration or broad project mutation is shown.
- The download URL is version-pinned to the package version.
