Identifies modification of the Time Provider. Adversaries may establish persistence by registering and enabling a
malicious DLL as a time provider. Windows uses the time provider architecture to obtain accurate time stamps from other
network devices or clients in the network. Time providers are implemented in the form of a DLL file which resides in the
System32 folder. The service W32Time initiates during the startup of Windows and loads w32time.dll.
