What it detects

This rule detects Mimikatz cloudap and cloudapkd module usage that extracts the Primary Refresh Token key material used for cloud single sign-on. The cloud lateral-movement research shows this yields tokens for pivoting from a compromised host to cloud identity. These module names are tool-specific and indicate active credential theft.
