Hi Diego,

Thanks for your response,
I understood that we need to play around with backdoors to bypass AV, what I am asking is how to generate a generic VBA command/powershell code which I could use in Microsoft office macro to allows download and execution of external .exe file just like the above generic download and execute macro, instead of a payload that require us to listen back via empire, veil etc. I created my FUD .exe backdoors already, I only need a generic download and execute powershell/VBA script that would run the code when macro is enabled, The above generic download and execute macro used by Zaid in the course does not bypass AV anymore no matter how the tweaking, which is very normal considering the lecture recorded time.

Is there a way I could get this done?

Thanks
