Detection & response playbook

Malicious package
  1. Find it

    Search your lockfiles and build artifacts for cheezokdi10 (version 0.1).

  2. If you installed it — respond

    Remove cheezokdi10 from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.

  3. Did it already run?

    If cheezokdi10 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. cheezokdi10 on PyPI has been identified as a malicious package (version 0.1 flagged). It should be removed immediately — do not install or keep it in your dependency tree.

Detect & block this

O3 blocks cheezokdi10-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
