Recently, there is a DDoS attack against South Korea & US networks. Vietnamese security experts, from Bkis, claimed that the master server of the cyber attacks was located in Britain. A report Korean authorities confirmed as credible.
Based on their investigation, about 166,908 "zombie" computers from 74 countries around the world have been used for the attacks and controlled by 8 Command & Control (C&C) servers. They successfully identify the master server after they hack into 2 of the 8 C&C servers.
With this, it allows them to determine the IP address of the master server, which is running Windows Server 2003, is 195.90.118.xxx and that it is located in the UK.
