What it detects

This rule matches Windows registry updates where the DumpType value under Windows Error Reporting LocalDumps is set to a DWORD value of 0x00000002 (Full Dump) for the lsass.exe local dump configuration. Setting DumpType to 2 enables creation of full memory dumps of LSASS, which attackers can use to extract credentials from process memory. Detection relies on registry set telemetry capturing the TargetObject path and the Details value indicating a full dump setting.
