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.
