Detection & response playbook

Credential / info stealer

  1. Find it

    Search your lockfiles and build artifacts for drop-events-on-property-plugin (version 0.0.2).

  2. If you installed it — respond

    drop-events-on-property-plugin 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 drop-events-on-property-plugin 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.
