If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

react-bootstrap-table-next-bg is a typosquat of react-bootstrap-table-next. Its package.json wires both preinstall and postinstall lifecycle hooks to beacon.js, which on every npm install collects hostname, username, current working directory, platform, INIT_CWD, npm_package_name, and the npm user agent, and sends them via plain HTTP GET to the hardcoded bare-IP collector http://100.24.177.136/cb/c469e93cbb94/depconf/react-bootstrap-table-next-bg. The destination is an unauthenticated IP endpoint unrelated to any legitimate publisher, the transport is cleartext, and the behavior fires automatically on default install without consent. The package self-labels as a 'dependency-confusion PoC', but that label is author-controlled and does not consent for arbitrary installers (including internal builds reached via name confusion) whose host identity and workspace path are shipped to the operator of the bare-IP collector.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
