Isn't this perhaps more reflective of the fact that bitcoins attract the more talented hackers and give them a reason to hack? I don't think these sites are any less secure than others, they just have targets painted on them.
You make me log back in to reply after I asked to be deleted haha.
I've never understood how sql injection attacks happen. They happen to the biggest of companies too. I can't imagine that the donation mod is extremely complicated, but before installing you at least look at every query and make sure it's not passing unsanitized variables to your database.
It's just like the xenland mining farm software that tons of sites are running. It has unpatched injection issues on every single one of them. The author thinks he is security minded. The sheep installing it don't have a clue. Good thing they aren't actually finding blocks with their dozen ghash running on them.
Problem isn't the skilled hackers. It's everyone else installing software they don't understand.
