Which versions of azure-langchain-example are malicious?

The following PyPI versions of azure-langchain-example are flagged malicious: 0.1.0. Treat any of these as compromised.

How do I remediate azure-langchain-example if I installed it?

azure-langchain-example 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 azure-langchain-example — how do I know if it already compromised me?

If azure-langchain-example 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 azure-langchain-example part of a known attack campaign?

Yes — azure-langchain-example is associated with the GENERIC-standard-pypi-install-pentest, IN-MAL-2026-020623 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 azure-langchain-example across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for azure-langchain-example (version 0.1.0).

Immediate action

pip uninstall azure-langchain-example

What this malware does

On import azure_langchain_example, the package's init.py starts a background daemon thread that issues a GET request to https://litellm.adversarylabx.com/.telemetry with the installer's hostname, resolved IP address, a timestamp, and the package name in the query string, using urllib.request.urlopen with a short timeout and silenced exceptions. The destination host is unrelated to the package's advertised purpose (a minimal LangChain wrapper for Azure OpenAI) and to any Azure or LangChain publisher domain. The behavior fires unconditionally at import without user consent or opt-out and is not mentioned in the README. Package metadata is placeholder (Your Name <[email protected]>) and the name resembles the Azure+LangChain ecosystem, consistent with a lookalike used to profile installers who mistype or guess an Azure/LangChain integration package name. An in-source comment labeling the request a harmless canary is author-controlled text that does not change the observed behavior.

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.
