  1. Challenge

    Getting Started in the Lab Environment

    Here are the initial instructions and explanation of the lab environment. Read this while your environment is busy creating itself from nothing. Yes, this violates physics; we know. How fun!

  2. Challenge

    Advanced Command History Manipulation

    This challenge will teach you how to clear and manipulate command history in Ubuntu to evade detection. You will delve into various techniques attackers use to cover their tracks by modifying or removing the command history. This involves clearing the history and configuring the environment to prevent future commands from being logged. By understanding these techniques, you can better anticipate and identify such evasion tactics during forensic analysis and incident response.

  3. Challenge

    Advanced Timestomp in Meterpreter

    This challenge involves using the Meterpreter tool to alter file timestamps to evade detection. This process consists of using Meterpreter commands to modify timestamps, and scripting these modifications for multiple files. You will understand how timestomping can be leveraged in real-world attacks, and how to detect and counteract such tactics.

  4. Challenge

    Advanced File Deletion and Obfuscation

    This challenge involves securely deleting files and obfuscating file deletion to evade detection. You will learn various methods attackers use to ensure that deleted files cannot be recovered. This includes basic deletion commands, advanced tools like ‘shred’ and ‘wipe,’ and techniques to overwrite file contents before deletion. The challenge also covers automation through scripting and methods to hide deletion activities from system logs. By mastering these techniques, participants can better understand how to detect and prevent attackers from covering their tracks.
