Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for wprwn6accxyz (version 0.0.1).
If you installed it — respond
Remove wprwn6accxyz 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 wprwn6accxyz 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.

O3 blocks wprwn6accxyz-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
