Free Identity-Breach CTF for Entra ID, M365, and KQL Practice by Varonis Threat Labs

Varonis Threat Labs offers a free browser-based Capture The Flag (CTF) exercise focused on Entra ID, M365, Azure logs, KQL, and identity-breach investigations. The scenario simulates a full-scale identity breach, requiring participants to track attacker activity, analyze data access, and identify exfiltration paths. The CTF includes four stages with 13 challenges, targeting intermediate to advanced skill levels. Participants who complete all stages by August 6 are eligible for a drawing to win a $2,000 Marriott gift card.
