Summary
Malicious code in pp-react-v5 (npm)
Details

pp-react-v5 is a dependency confusion package published at the inflated version 10.0.0 to win npm resolution over any internally-hosted package of the same name. The package contains only a package.json with no functional source code.

On installation the preinstall script executes a wget command that sends a GET request to http://q9ou9xtw.requestrepo.com/ with the current username (whoami), working directory (pwd), and hostname as query parameters, beaconing the victim machine's identity to the attacker-controlled endpoint.
