Detection & response playbook

Credential / info stealer
  1. Find it

    Search your lockfiles and build artifacts for fromwherebitch (version 0.1.3).

  2. If you installed it — respond

    fromwherebitch 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.

  3. Did it already run?

    If fromwherebitch 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.

Frequently asked questions

No. fromwherebitch on PyPI has been identified as a malicious package (version 0.1.3 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
