ScheduleRunner - A C# tool with more flexibility to customize scheduled task for both persistence and lateral movement in red team operation
Scheduled task is one of the most popular attack technique in the past decade and now it is still commonly used by hackers/red teamers for persistence and lateral movement.
A number of C# tools were already developed to simulate the attack using scheduled task. I have been playing around with some of them but each of them has its own limitations on customizing the scheduled task. Therefore, this project aims to provide a C# tool to include the features that I want and provide enough flexibility on customizing the scheduled task.
