You've spent money on security products that escalate nothing. You have a 24/7 SOC that hardly pays attention to their tools, or knows how to use them. You have intelligence feeds but have no idea what consumes them. Logs are inaccessible, slow to query, or non-existent. Defenders have stopped hunting and lost a sense of purpose.
That means it’s time for a Red Team to come in and fuck shit up.
This is an example of a red team exercise done right: realistic.
During the response, we had to “cancel” vacation plans, calm panicked employees, and negotiate the tough decisions around production system shutdowns. Defenders were tasked with building a recovery plan which considered how much, if not all, we’d have to be rebuild. This is a significant amount of the headache you deal with when you’re really in the thick of a worst case intrusion, and has little to do with forensics or IR.
Next morning, we broke the news to the team that this was a staged (albeit real) good-guy intrusion. There was long silence, red faces, and we were doing a lot of explaining. I wasn’t sure how the team would react. A former FBI agent we hired to do malware research broke the silence with a “…Then that’s fucking awesome!” and the room lit up.
