lolwut, SQLi is sophisticated and takes mad skills now? The methods employed are very low-brow to be charitable, brah. To be completely honest, I don't think Lulzsec is the first to discover this at all. They're just being loud about it all. For a sophisticated popular hack recently, look at the work by zerofor0wned or the Stuxnet worm (not classifying the two in the same category of course).
