OpenSSF Malicious Packages via OSV

Summary

Malicious code in web-main (npm)

Details

package.json declares `preinstall: node index.js`, causing index.js to execute automatically on `npm install`. The script collects os.hostname(), os.userInfo() (username/uid/gid/shell), platform, arch, homedir, and the stdout of `whoami`, `id`, and `pwd` via child_process.exec, then POSTs the aggregated JSON to a hardcoded endpoint at https://smi54v4uvb9q7ve5t6fnyro16scj0co1.oastify.com/system-info (a Burp Collaborator out-of-band host). No legitimate functionality is present; the package's sole effect on install is host reconnaissance and exfiltration to an attacker-controlled OOB collector.

Decision reason

OpenSSF Malicious Packages via OSV confirms web-main@22.1.2 as malicious (MAL-2026-16153): Malicious code in web-main (npm)
