MAL-2026-11192 Malicious code in test2221 (npm)

package.json declares preinstall and postinstall lifecycle scripts that run curl against http://54.37.234.136/voicemail over plain HTTP, sending the installer's username (whoami), hostname, working directory, and a timestamp as query-string parameters. Both hooks fire automatically on npm install, transmitting installer host identifiers to a hardcoded bare-IP endpoint with no relation to any documented package purpose. The behavior matches reconnaissance-beacon shape suitable for follow-on targeting of the installer's host.

The OpenSSF Package Analysis project identified 'test2221' @ 2.2.4 (npm) as malicious.
