+### Command Syntax:
+- `atexec.py domain/username:password@[hostname | IP] command`
+
+### Characteristics:
+- Executes commands remotely but does not provide shell access.
+- Creates a Scheduled Task with a random 8-character mixed-case alpha string.
+- Uses `cmd.exe /C` to run commands, outputting results to `C:\\Windows\\Temp\\<random>.tmp` before deleting the file.
+- **NOT detected and blocked by Windows Defender by default**.

+    - `4672` - Special privileges assigned to logon.

+    - `106`, `325`, `129`, `100`, `200`, `110`, `141`, `111`, `201`, `102` (Task lifecycle).
+3. **IF ENABLED**:
+    - `4688` - Process creation (`cmd.exe` spawning tasks or executing commands).
+    - `4698` - Scheduled task created.
+    - `4699` - Scheduled task deleted.

+### Example Detection Indicators:
+- Multiple rounds of Event IDs (4776, 4672, 4624).
+- Temporary `.tmp` files in `C:\\Windows\\Temp` with scheduled task output.
