Worldwide distribution of malcode and DDoS attack by Arbor
The below charts are worldwide distribution of malcode and DDoS attacks by Arbor networks.
The first one is a set of major malcode distribution points for May, 2008, by country, while the second one is who are hosting the DDoS attack botnets (these are the controlling servers, NOT the attacking bots). This is the number of attacks commanded by hour by server country.
It seems that too much malcode and DDoS attackes are originated from China. If this data is true, it betrays that China ISPs and government should do more to clean the network. Meanwhile, this means a great security market potential at China, even though the security market volume is relatively very small at this moment (less than 2B$ per year)
