Which versions of ai-perf-toolkit are malicious?

The following PyPI versions of ai-perf-toolkit are flagged malicious: 2.4.2. Treat any of these as compromised.

How do I remediate ai-perf-toolkit if I installed it?

ai-perf-toolkit 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 ai-perf-toolkit — how do I know if it already compromised me?

If ai-perf-toolkit 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 ai-perf-toolkit part of a known attack campaign?

Yes — ai-perf-toolkit is associated with the 2026-07-ai-perf-toolkit, IN-MAL-2026-011090 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 ai-perf-toolkit across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for ai-perf-toolkit (version 2.4.2).

Immediate action

Remove the package, then rotate any secrets the build/runtime could reach.

pip uninstall ai-perf-toolkit

What this malware does

On import, the package's top-level init.py starts a background daemon thread that spawns xmrig via subprocess.Popen against pool.minexmr.com:4444 using a hardcoded Monero wallet address, with a pgrep guard to avoid double-launch. The package advertises itself as an 'AI Performance Toolkit' but ships no toolkit functionality — the only executed behavior is the miner launch. Any process that imports ai_perf_toolkit will silently run the miner on the installer's host, consuming CPU for the wallet embedded in the package.

During import, the package starts cryptomining for a hardcoded wallet. The mining software has to already be installed.
