Malicious code in @uol-afiliados/affiliated-config-lib (npm)

@uol-afiliados/affiliated-config-lib@102.0.0 declares a preinstall hook (node index.js) that shells out via require('child_process').exec to run curl against a subdomain of hqbv58hgt1sjk7vf7ru4o0mwzn5etahz.oastify.com (Burp Collaborator out-of-band interaction infrastructure). The subdomain is constructed with shell command substitution $(hostname).$(whoami), so the installer's host name and current user name are embedded in the DNS/HTTP request and sent to the attacker-controlled collector automatically on npm install. The package ships no legitimate functionality — the sole install-time effect is host/user identifier exfiltration. The scoped name @uol-afiliados/* mimics an internal organization namespace, consistent with dependency-confusion reconnaissance.

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.
