Summary
Malicious code in crosswalker (npm)
Details
package.json declares `preinstall: node index.js`, causing index.js to run automatically on `npm install`. The script collects hostname, platform, arch, homedir, username, uid/gid, shell, OS info, cwd, and the output of `whoami` and `id`, then POSTs the JSON payload to a hardcoded URL at `https://kbz9yyzq2mtljdwwf6r0tpzlfcl39txi.oastify.com/detox56`. The destination is a Burp Collaborator subdomain — out-of-band infrastructure used to confirm exfiltration / RCE during dependency-confusion reconnaissance. Installer host and user identifiers leave the machine without consent on every install.
