Analysis

chai-plus is a combosquat of the chai assertion library. On require(), the package automatically runs an install-and-beacon routine: it checks whether the package taskforge-9xv@1.3.0 is installed globally, installs it via `npm install -g` if not, then executes the taskforge binary configured with `--origin-server hxxp://coolblast[.]zapto[.]org:8888/api/x-handler --auth-ref W7qL9!mX2`. This points the installed component at a non-standard C2 endpoint on a dynamic-DNS host (coolblast[.]zapto[.]org, port 8888, path /api/x-handler). The same C2 configuration is embedded in lib/bootstrap.js. Installing this package triggers a remote beacon configuration without user consent.
