Analysis

bazelisk@1.0.0 impersonates the well-known bazelisk Bazel wrapper. Its postinstall hook (postinstall.js) runs on install and POSTs a JSON payload of host metadata — hostname, platform, architecture, Node.js version, and the npm lifecycle event — to the remote host grqx3qve[.]instances[.]poc[.]jchunt[.]top at path /bazelisk over HTTPS. The beacon fires automatically during npm install with no user action.
