i have heard more of these stories in recent times lol...as a matter of fact heard some tech geeks on https://venomthreads.com are the best when it terms gaining, revoking and recovering access into a database and with a certification to show for it. i also have the believe too that it's only people with profound tech knowledge that can pull off stuffs like database hacks.
RE: Hacked databases, how I found my old account(s) and new accounts made by invaders due to being compromised.
