What it detects

This rule detects writes to a TitanPlus registry key, the location where the intrusion described by Truesec stored encoded command-and-control server addresses using character substitution. Adversaries hide C2 configuration in an obscure registry value to survive reboots and evade file-based detection, making writes to this named key a targeted persistence and C2 indicator.
