# Services.exe

### What is services.exe?

`services.exe` is a fundamental Windows system process that acts as the **Service Control Manager (SCM)**. It is responsible for managing and controlling the lifecycle of Windows services, which are background processes that perform various system functions without direct user interaction.

**Key Functions:**

* **Managing Services:** Starts, stops, pauses, and controls Windows services.
* **Service Configuration:** Reads service configurations from the Registry to determine startup behavior.
* **Service Interaction:** Provides an interface for the OS and other processes to interact with services.
* **Security Context:** Manages the security accounts under which services run.
* **Failure Recovery:** Configures actions to take if a service fails (e.g., restart).

**In essence, `services.exe` is the central authority for running essential background processes that enable Windows functionality.**

### services.exe and MITRE ATT\&CK

Attackers leverage `services.exe` for **Persistence (TA0003)** and **Execution (TA0008)** by manipulating Windows services. They can **create or modify services (T1543.003 Windows Service)** or **abuse existing services for execution (T1569.002 Service Execution)**. Monitoring for unusual service creation or changes is key to detection.
