|

Windows operating systems are utilizing the time provider architecture in order 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 System32 folder. The service W32Time initiates during the startup of Windows and loads w32time.dll. Adversaries may
|
|
abuse this architecture to establish persistence, specifically by registering and enabling a malicious DLL as a time
|
|
provider.
