package.json declares preinstall: node index.js, which fires automatically on npm install. index.js loads child_process/os/https, runs whoami and id, collects host identifiers (os.hostname, os.platform, os.arch, os.homedir, os.userInfo username/uid/gid/shell, os.type, os.release, process.cwd), and POSTs the collected JSON to a hardcoded Burp Collaborator (OAST) subdomain at https://3quc59n15cfcretszaygwfm9v01rphd6.oastify.com/detox56. The package ships no functional code beyond this beacon, has empty description/author, and is published under the @broadpeak scope — consistent with dependency-confusion reconnaissance impersonating an internal Broadpeak package. Installing this package leaks installer host/user identifiers to an attacker-controlled out-of-band endpoint and confirms code execution inside the target's build environment for follow-up targeting.
