The velabuild npm package contains embedded malicious code that includes a base64-encoded RSA private key used to establish SSH connections to an attacker's server. This private key is identical for every installer, granting anyone who installs the package valid SSH credentials to the attacker's server. While the package does not execute attacker-controlled code during installation or modify the installer's filesystem beyond a temporary key file, it enables remote command execution via SSH when specific subcommands are invoked. The package's signup and login commands transmit user credentials over this SSH tunnel. Systems with this package installed should be considered fully compromised.
