Which versions of pydantics are malicious?

The following PyPI versions of pydantics are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate pydantics if I installed it?

pydantics is a typosquat — you almost certainly intended a legitimately-named package. Remove pydantics, install the correct package, and rotate any secrets exposed during the install since post-install scripts may have already run.

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

If pydantics 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 pydantics part of a known attack campaign?

Yes — pydantics is associated with the GENERIC-local-typosquatting 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 pydantics across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for pydantics (version 1.0.0).
