title: New TimeProviders Registered With Uncommon DLL Name
id: e88a6ddc-74f7-463b-9b26-f69fc0d2ce85
status: experimental
description: |
Detects processes setting a new DLL in DllName in under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProvider.
Adversaries may abuse time providers to execute DLLs when the system boots.
The Windows Time service (W32Time) enables time synchronization across and within domains.
