lol these guys get worse by the day. It's true that there are a couple of high level hackers than jump on the ship as and when they feel like it. And it's true that they do have some older leaders who guide the sheep in the general direction of proper mischief. But most of the time it's a bunch of noobs running exploit searching software against every site they possible can and hoping they find one with a vulnerability.
Anyone could download the same software and hit hundreds of sites until they also find one which is vulnerable and use the same software to break in through that vuln. Your average heavy internet user could manage this without breaking a sweat. No hacking skills needed. Then you just have to come up with some story about why you attacked that site so you don't seem like a noob that's just looking for any random unsecured server.
