The wordpress site I told my friend her friends I would take a look at made me feel a bit like a real hacker.

Without knowing them I guessed their username and password for the admin panel in 15 tries. Today they send me the password and username via email.
I just told them I already had access and that they should change the password.

TL;DR first off you are lazy, it isnt such a long text, but the real tldr is "Me Hackerboy"
