The package's postinstall lifecycle script (postinstall.js, wired via scripts.postinstall in package.json) checks the installer's hostname against a hardcoded allowlist value ('ubuntu-fc-uvm') and, on match, spawns /bin/bash with a reverse-shell one-liner opening an interactive TCP shell to 14.225.210.85:80. The script uses child_process.exec, includes retry logic and a 60-second timeout, and runs automatically on npm install. The hostname gate indicates a targeted-dropper shape aimed at specific installer environments; on matching hosts the operator obtains full interactive command execution on the installer's machine.
- CWE-506 - The product contains code that appears to be malicious in nature.
