Description
The express-ini npm package version 12.1.10 contains malicious code that executes during installation. The package's postinstall script runs heavily obfuscated JavaScript which downloads, decrypts, writes, and executes additional code on the installer's machine. The package masquerades as an Express.js utility but functions as a dropper for remote code execution at install time.
