Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for caixaequ2ahzoop (2 malicious versions).
If you installed it — respond
Remove caixaequ2ahzoop 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.
Did it already run?
If caixaequ2ahzoop 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.
