Summary
In this chapter, we demonstrated the basic concepts of evasion for common security controls. This is just the tip of the iceberg, as we did not cover AV/EDR bypass, tool customization, shellcode loaders, and much more. We covered built-in controls (AMSI) as well as enhanced security components that can be deployed by Group Policies in the domain (AppLocker and Enhanced PowerShell Security). Then, we had a look at possible detection mechanisms that can be enforced in Windows with the help of Sysmon and ETW.
In the upcoming chapters, we are going to use different tools and focus on concepts. We will run tools on machines with Microsoft Defender disabled. It is important to show that evasion is a vital part of the process and always comes first. The key to success is to know what our tools are doing under the hood, and what IOCs we leave on compromised machines.
The next chapter will be devoted to domain enumeration. We will see how it can be done with different tools, what the well-known patterns are for such activities, and how not to miss important bits.
