What it detects

This rule detects modification of the EnableLUA policy value to zero under the system policies key, which disables User Account Control. The REMCOS RAT performs this change to weaken host defenses and enable silent privilege escalation. Disabling UAC system-wide is rarely legitimate and represents a significant defense evasion action.
