Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for fire-eye-bcs (3 malicious versions).
If you installed it — respond
Remove fire-eye-bcs 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 fire-eye-bcs 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 fire-eye-bcs-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.
