What it does
A dependency-confusion package published 2026-11-07 under the name react-bootstrap-table-next-bg with the inflated version 9.9.9 to win resolution over a private package. Both its preinstall and postinstall hooks run 'node beacon.js', which sends the machine's hostname, user name, current working directory and platform as query parameters of a cleartext HTTP GET to the hardcoded endpoint http://100.24.177.136/cb. Self-described as an authorized dependency-confusion proof of concept. Remove the package and treat the hostnames, user names and paths of affected build machines as disclosed.
