AlienVault has used the data from the first 5 months of operation from its Open Threat eXchange to build an infographic that shows the sort of content it is seeing. The malicious IP addresses are plotted based on country around the world. The IPs are attributed to “crimes” like pushing malware, attacking honeypots, etc. They could be innocent computers infected with malware or they could be malicious bots.
