Detection & response playbook

Credential / info stealer
  1. Find it

    Search your lockfiles and build artifacts for decoris (2 malicious versions).

  2. If you installed it — respond

    decoris 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 decoris 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. decoris on PyPI has been identified as a malicious package (versions 0.3.0, 0.3.3 flagged). It should be removed immediately — do not install or keep it in your dependency tree.

Detect & block this

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