Malicious packageFind it
Search your lockfiles and build artifacts for cursed-module (4 malicious versions).
If you installed it — respond
Remove cursed-module 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 cursed-module 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.
