Malicious packageFind it
Search your lockfiles and build artifacts for oc-aa-module-client (all published versions).

Remove oc-aa-module-client 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?
