@uol-afiliados/affiliated-config-libnpm
Advisory published Updated
@uol-afiliados/affiliated-config-lib is a confirmed malicious npm package (MAL-2026-16370) that steals credentials and exfiltrates sensitive data (malicious version 102.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in @uol-afiliados/affiliated-config-lib (npm)
What this malware does
@uol-afiliados/[email protected] 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.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for @uol-afiliados/affiliated-config-lib (version 102.0.0).
If you installed it — respond
@uol-afiliados/affiliated-config-lib is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If @uol-afiliados/affiliated-config-lib was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks @uol-afiliados/affiliated-config-lib-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
