They might be looking for client addresses of specific targets. Then again, if they were trying for a "bank shot" attack on some particular target, they almost certainly wouldn't be trashing the front page to let the world know that the whole site is compromised.
Oh those turk hackers. Remember the mid-2000s, when searching google dork on a certain public exploit, one would most certainly find lots of already defaced websites? Even on some forsaken lice breeding forum with 2 users, there would always be mad photoshop collage with star and crescent on dark background, and a message to those few poor visitors, who probably would not even comprehend what is going on.
Anyway, what's up with Turkey and hacking?
Ever seen a graffiti of someones name you can't even decipher on the back of a trash can at the far off bus stop near the forest? It's kind of like that.
Well, that makes sense. But why announce that you're Turkish? For example, there are lots of Russian hackers and skiddies, but I have never seen a cr3w called RussiaStrongSec.
Sometimes they are spreading a political message (I've seen more Syrian hackers than Turkish on defaced websites recently, incidentally) so they want to spread their identity. Just like hacking groups that are in it for infamy spread their identity.
Of course in some cases they may be false flag operations, always a possibility worth keeping in mind.
