If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

The package's postinstall lifecycle script runs unconditionally on npm install. It collects host identifiers (hostname, platform, architecture, kernel release, uid/gid, CPU count, memory) and internal network interface addresses, base64-encodes the payload, and POSTs it over plain HTTP to the hardcoded subdomain vml73pdk3ft3t434ssjycv4khbn2btzi.oastify.com — a Burp Collaborator (OAST) callback host used to confirm code execution on the installer. The package has no other functionality; its sole install-time effect is the outbound beacon carrying installer reconnaissance data to an attacker-controlled domain.
