Description

A client calls in crisis. Their network team identified an unusual 2TB spike in traffic from their production Microsoft SQL server and confirmed it was not a backup job and such a spike had never previously been observed. Their internal SOC performed triage and found that ntds.dit was dumped on the primary domain controller around the same time MSSQL data was exfiltrated. There are 30,000 users in their Active Directory environment, 10+ user VPNs spanning the globe, and multiple site-to-site tunnels to business partners. You are invited to join an emergency conference call with the CISO, all heads of engineering, and inside counsel. They look to you to manage the crisis. Are you confident in the cockpit? If so, we should talk.
