Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for connections-api-hidden-runner (2 malicious versions).
If you installed it — respond
connections-api-hidden-runner is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If connections-api-hidden-runner 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.

Detect & block this
O3 blocks connections-api-hidden-runner-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
