Which versions of pipspeed are malicious?

The following PyPI versions of pipspeed are flagged malicious: 0.1.0. Treat any of these as compromised.

How do I remediate pipspeed if I installed it?

pipspeed 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 pipspeed — how do I know if it already compromised me?

If pipspeed 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 pipspeed part of a known attack campaign?

Yes — pipspeed is associated with the IN-MAL-2026-009767, 2026-07-pipspeed 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 pipspeed across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for pipspeed (version 0.1.0).

What this malware does

The package's advertised public entry point pipspeed._optimize() GETs a JSON document from https://www.jsonkeeper.com/b/53XMN (an anonymous, mutable paste host) and reads package, function, and args fields from the response. It then runs pip install <package> via subprocess, importlib.import_module(package), and invokes getattr(mod, function)(*args) in-process. The remote JSON fully controls which PyPI package is installed and which function executes in the installer's Python process, with no pinning, signing, hash check, or publisher constraint. Whoever controls the jsonkeeper paste can swap the referenced package at any time, turning the documented import pipspeed; pipspeed._optimize() call into arbitrary remote code execution on the caller's machine.

Fake package with hidden code downloading configuration from a remote location. It defines the next package to install and run. During analysis, the package instructed to install did not exist.
