I'm trying to get my own cc, cvv. I am studying database intrusion of websites, but I came across a lot of information. What do I really need? PHP language? Metasploit? kali I tried to invade with bruteforce through port 3306 but I did not succeed. I have read various forms of penetration and have not been successful. Could someone tell me if I'm on the right path?
