Detection & response playbook

Malicious package
  1. Find it

    Search your lockfiles and build artifacts for aaaa89852889 (version 1.0.0).

  2. If you installed it — respond

    Remove aaaa89852889 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 aaaa89852889 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.
