Purple Teaming incorporates blue team "monitor, detect and respond" capabilities with the red team "surveil and assault" strategies to support one key mission: To improve the organization's security posture. To test threat detection and response capabilities, red teams are charged with simulating real-world threats - the more realistic the better!

Today's adversaries are making use of "Live Off the Land" strategies, repurposing native Windows binaries to achieve strategic goals such as privilege escalation, lateral movement, persistence and C2 communication. Not only do these strategies allow attackers to evade AV & EDR detection, but Blue teams often have poor concept of baselining for usage of these native Windows binaries within their own environment.

This 4-hour training session will provide the full purple teaming experience, with walk-throughs of LOLBin attacks to achieve "actions on objective", ensuring survivability through persistence and remote execution for lateral movement. Attendees will also perform live triage and memory analysis on affected targets to detect indications of LOLBin abuse. Key takeaways will include enterprise-scaled detection and mitigation strategies to prevent future LOLBin abuse in your own environment. Join incident response analyst and SANS Instructor Alissa Torres for exposure to some of these sneaky LOLBin and LOLScript techniques and how they can best be employed in a purple team collaboration.
