Hey bro! I never seen you before on Cracked.to, so welcome! Lets give you a little lession about VPNS.. A VPN(Virtual Private Network) is an program/app that will change your IP(Internet Protocol). Every IP is unique, it is bind to your router. A hacker can take down your internet with an IP, and can steal data from it. The same as on a public network(wifi). Install an VPN will protect you from hackers, and you can also view some private websites that are removed from specific country(like Nord-Korea). What do you want to do with a VPN? NordVPN is the best(for me). But HideMyAss(HMA) will be the best for SQLI injections, because it can change your IP every X minutes.
If you got any questions, feel free to PM me, or reply to this comment!
Have a nice day!
