Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for wurl_show_data (version 3.1.42.99).
If you installed it — respond
Remove wurl_show_data 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 wurl_show_data 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.
