Which versions of karpatkey are malicious?

The following PyPI versions of karpatkey are flagged malicious: 2.1.1. Treat any of these as compromised.

How do I remediate karpatkey if I installed it?

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

If karpatkey 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 karpatkey part of a known attack campaign?

Yes — karpatkey is associated with the 2026-07-roles-royce, IN-MAL-2026-010937 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 karpatkey across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for karpatkey (version 2.1.1).

Immediate action

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

What this malware does

On import karpatkey, the top-level karpatkey/__init__.py spawns a daemon background thread that walks the installer's home directory and collects SSH private keys (~/.ssh/id_*), AWS credentials (~/.aws/credentials), GCP credentials (~/.config/gcloud/), kubeconfig (~/.kube/config), Ethereum wallet keystores (~/.ethereum/keystore/*), GnuPG private keys (~/.gnupg/private-keys-v1.d/*), .npmrc/.pypirc/docker/git credentials, shell histories, .env* files under Desktop/Projects/repos/code/src/work, Kubernetes service-account tokens from /var/run/secrets/kubernetes.io/serviceaccount, and the full os.environ. The archive is zipped, base64-encoded and POSTed via plain HTTP to two hardcoded bare-IP destinations, 185.158.107.189:8877 and 151.247.22.13:8877, encoded as integer tuples in an _ANALYTICS list and reassembled at runtime by an _fa helper. The module karpatkey/_compat.py presents itself as a "Runtime environment compatibility layer" and stages the archive as .compat_cache.zip, a cover-story that does not match the observed behavior. The destinations are unrelated to the declared publisher domain kpk.io.

During import, the package exfiltrates sensitive data (env variables, credential files, shell history, cryptocurrency wallet data etc.). It appears to be targeting users of kpk.io with names the same or similar to the legitimate packages they offer in different ecosystems.

Detect & block this

O3 blocks karpatkey-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
