Each individual tool has its own README file with usage information and compile instructions.
It is also possible to directly import all tools by loading the OperatorsKit.cna script using the Cobalt Strike script manager. Furthermore, mass compiling can now be done using the compile_all.bat script from within the x64 Native Tools Command Prompt for VS <2019/2022> terminal.
A round of virtual applause to reenz0h. Multiple tools in this kit are based on his code examples from the Malware Development and Windows Evasion courses. I highly recommend purchasing them!
Furthermore, some code from the CS-Situational-Awareness-BOF project is used to neatly print beacon output.
