Hey everyone I'm from Argentina. I have a problem, I learn through youtube tutorial or some forums thinks like crack wifi, backdoors, phishing and more but I can't do the next step. In thinks like backdoor avoiding windows defender in windows 10 or things like that. I can't find new things to improve my skills (I think that there are tutorial but with old methods and for one reason I don't know why there aren't more as in the past) and I don't know where I hace to search. Should I search in Tor forums ? Which ?
Please if you reply this help me and not said "learn for yourself" remember everybody have been a noob once time. I'm just asking for where can I learn
Thank u
