Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for worldskills (version 1.0.6).
If you installed it — respond
Remove worldskills 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 worldskills 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.
