When conducting a penetration test, there is a level of trust that is defined between you and your client. When you drop any payloads into their environment, such as evading the antivirus to create a backdoor to your system, you need to ensure that the payload connects back to you only. There shouldn't be any bugs in the code that could lead to a real compromise of the client's environment.
As you work through the various tools that are defined in this section, please ensure that you explicitly define your system's IP that the target would connect back to. Doing so will ensure that you enforce the concept of trust in the initial learning steps of your career.
