Which versions of ibmodules are malicious?

The following PyPI versions of ibmodules are flagged malicious: 0.1.0, 0.1.1, 0.1.2. Treat any of these as compromised.

How do I remediate ibmodules if I installed it?

Remove ibmodules from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.

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

If ibmodules 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 ibmodules part of a known attack campaign?

Yes — ibmodules is associated with the GENERIC-simple-tests, RLMA-2026-01683 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 ibmodules across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for ibmodules (3 malicious versions).

What this malware does

Packages that might be part of testing for pentesting / malicious activity / joy, with suspicious activity that does not present any real harm.

Campaign: GENERIC-simple-tests

Reasons (based on the campaign):

The package overrides the install command in setup.py to execute malicious code during installation.

Detect & block this

O3 blocks ibmodules-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
