T1547.003 Time Providers — Attack Simulation

Adversaries may abuse time providers to execute DLLs when the system boots. The Windows Time service (W32Time) enables time synchronization across and within domains. W32Time time providers are responsible for retrieving time stamps from hardware/network resources and outputting these values to other network clients. Time providers are implemented as dynamic-link libraries (DLLs) that are registered in the subkeys of…

Technique description

At least one platform-compatible Atomic procedure is documented. Individual review, lab prerequisites, and validation remain required.
