Previously, threat actors focused on attacking computers to gain access into an environment. Why are identity-based attacks suddenly so popular? In this blog, we are going to define what password sprays are, detail DART’s investigation techniques and approach to responding to password spray attacks, and outline our recommendations for protecting against them. This threat is a moving target with techniques and tools always changing, and Microsoft continues to find new ways to detect these types of attacks and help protect its customers. Over the past year, the Microsoft Detection and Response Team (DART), along with Microsoft’s threat intelligence teams, have observed an uptick in the use of password sprays as an attack vector.
