WTF? PC World
The U.K. was the likely source of a series of attacks last week that took down popular Web sites in the U.S. and South Korea, according to an analysis performed by a Vietnamese computer security analyst.
The results contradict assertions made by some in the U.S. and South Korean governments that North Korea was behind the attack. Security analysts had been skeptical of the claims, which were reportedly made in off-the-record briefings and for which proof was never delivered.[...]
The computers used to send the flood of requests had been infected with a virus that allowed attackers to use them anonymously.
Every three minutes the infected computers randomly selected one of eight servers to connect to and receive orders, said Nguyen Minh Duc, senior security director at Bach Khoa Internetwork Security (Bkis), in a blog posting on the company's Web site. Bkis says it gained control of two of the eight servers and through this has been able to discover the master server.
That server has an IP address in the 195.90.118.x range, Nguyen said.
