Official description
[email protected] executes a preinstall script that auto-runs on
npm install. The script collects the installer's OS username, hostname, and current working directory, then walks up parent directories to read the surrounding project's package.json name, author, and version. The collected JSON payload is hex-encoded and exfiltrated in chunks via DNS lookups to attacker-controlled subdomains under jgl.red (form: <seq>.<hex>.x.da5u87oh92rc72pp1dngqfc6hp8gwshm6.o.jgl.red), with a fallback DNS query on error. A source comment (// x-hackerone: kokonut) suggests dependency-confusion / bug-bounty reconnaissance framing, but the payload identifies the installer and discloses the name and version of the surrounding (likely private) parent package to a third party.What should I do about MAL-2026-14472?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
