The Anonymous Team Have Also Developed their own DDoS tool which is said to exploit SQL vulnerabilities to support the group's future campaigns. Previously they had been using LOIC for many of their operation . But due to this tool many of the Anonymous got caught may the tool was not capable of hiding their tracks . So this time they made their own.
According to Developer "RefRef is a revolutionary DoS java site. Basically, by using an SQL and .js vulnerability, you can send a page request packet from your home computer with embedded .js file, because of the vulnerability in the SQL/Javascript engine on MOST websites, the site actually TEMPs the .js file on its own server. So now the .js is in place on the host of the site. Next since you still have the request, it picks up the .js file, and all of the requesting for packets power happens on the server, not the requestee. I send two packets from my iphone, and everything else happens on the server. Basically eats itself apart, because since both are on the server, its all a local connection."
