Storm-0940 Password Spray Hunt: Many Accounts From One Address, Scripted Clients and Campaign Addresses
Detects an address whose sign-ins are mostly failures across many accounts in a short window, with scripted clients and Storm-0940 campaign addresses flagged, which is how the password spray in Microsoft's ARTEX reporting looked. It does not cover the ConnectWise application sign-ins (service principal events) or a spray spread over many addresses. The query ran without errors in a live tenant.
