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.

package.json declares preinstall and install lifecycle scripts that, on npm install, collect whoami, hostname, current working directory, and npm_package_name, base64-encode the concatenation, and transmit it to subdomains of callback.m0chan.co.uk via both an HTTPS GET (curl to https://<sub>.callback.m0chan.co.uk/<b64>) and a DNS lookup (nslookup against <pkgdns>.<sub>.callback.m0chan.co.uk). The 99.99.99 version and scoped name pattern are consistent with a dependency-confusion beacon targeting an internal @hzero-front-ui scope.
