According to zone-h.org the attack against Sony BMG websites was carried out by one defacer, presumably from Turkey, who signed using the nickname "LuCky_Luke". The Warner attack was performed by a crew of defacers who come from Chile, known as "byond hackers team". That attack seemed to come from people who don't like capitalism much.
