Firewall exposure and follow-on compromise
A case began after a permissive GCP internet-firewall rule exposed Windows and Linux servers. It recorded the rule’s creator and disablement times, assigned investigation tasks, and initially marked exploitation as unconfirmed. The updated case documented an FTP dictionary attack, recovered credentials, downloaded files, and attempted SSH access. section 11.1.7 section 11.1.10
