Which versions of uus are malicious?

The following PyPI versions of uus are flagged malicious: 912.6. Treat any of these as compromised.

How do I remediate uus if I installed it?

uus 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.

I already installed uus — how do I know if it already compromised me?

If uus 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.

Is uus part of a known attack campaign?

Yes — uus is associated with the RLMA-2024-11203, 2024-11-byted-dast, RLUA-2026-00882 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find uus across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for uus (version 912.6).

Part of a larger attack: 2024-11-byted-dast published 183 malicious packages. See the full campaign →

What this malware does

A campaign of probably pentest packages flooding PYPI. Installing the package or importing the module triggers reporting basic info like hostname, path and the username to the package author. There is no other purpose of the package.

Category: PROBABLY_PENTEST - Packages looking like typical pentest packages, but also anything that looks like testing, exploring pre-prepared kits, research & co, with clearly low-harm possibilities.

Campaign: 2024-11-byted-dast

Reasons (based on the campaign):

The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk.

Detect & block this

O3 blocks uus-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
