Which versions of postgresql-connector-python are malicious?

The following PyPI versions of postgresql-connector-python are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate postgresql-connector-python if I installed it?

postgresql-connector-python 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 postgresql-connector-python — how do I know if it already compromised me?

If postgresql-connector-python 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 postgresql-connector-python part of a known attack campaign?

Yes — postgresql-connector-python is associated with the GENERIC-standard-pypi-install-pentest 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 postgresql-connector-python across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for postgresql-connector-python (version 1.0.0).

Immediate action

pip uninstall postgresql-connector-python

What this malware does

Installing the package or importing the module exfiltrates basic information about the host, and the package has no other purpose.

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: GENERIC-standard-pypi-install-pentest

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