Imagine I create a machine (laptop maybe) in which I don't use a browser, I just perfom an attack and use macchanger, VPN or maybe proxychains. And I'm on an open wifi network. The question is how do they track me? How tracking works?
I also want to know if I changed my network adapter on the laptop, is still there any unique identifying information that could leak from my laptop? If yes, then what type of information?
