Details
dcfarguscert@999.0.1 registers both preinstall and postinstall lifecycle scripts that invoke src/telemetry.js. On install, telemetry.js collects host identifiers (os.hostname(), os.userInfo().username, OS release, process.platform, process.arch, Node version, CI flag) and the output of `npm ls -g --depth=0 --json` (the installer's globally installed npm package inventory), then POSTs the aggregated payload over plain HTTP to the hardcoded endpoint http://16-171-38-148.sslip.io:8080/api/install (bare IP 16.171.38.148 encoded via sslip.io). The version number 999.0.1 and the package description referencing a 'dependency test' with 'check ips' are consistent with a dependency-confusion beacon that fires unconditionally on install without any user consent or opt-out.
