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.

magika-js is a typosquat of Google's magika library. The postinstall lifecycle script collects installer host identifiers (hostname, platform, arch, node version, package name, npm lifecycle event, timestamp) and POSTs them as JSON to the hardcoded endpoint https://ucjtw03t.instances.poc.jchunt.top/magika-js. The beacon fires automatically on npm install with no opt-in and no documented purpose served by the transmission, sending installer machine data to a non-publisher domain. A source.txt pointer to github.com/google/magika reinforces the impersonation of Google's project.
