Anonymous is all set to launch its new operation of hacking and defacing the top websites with a new DDoS tool . The tool is considered as the successor of their previous DDos tool called LOIC.
The tool is very effective, a 17-seconds attack from a single machine resulting in a 42-minute outage on Pastebin yesterday. As expected, the Pastebin admins weren't very happy with their platform being used for such tests and tweeted "Please do not test your software on us again."
The tool works by turning the servers against themselves. It sends malformed SQL queries carrying the payload which in turn forces the servers to exhaust their own resources. However, the tool's GUI does have a field for inputting the refresh interval so it might combine traditional forms of HTTP hammering with the new technique.
Some security experts have been skeptical that the success of Anonymous's DDoS attacks can be explained through LOIC alone. They proposed that some of the group's supporters also have access to botnets, a theory that has partially proven to be correct.
