After closely analyzing the domains, experts found they all resolve to the IP address of a server located in the Czech Republic. The server hosts over 100 domains utilized as exploit sites and gateways for adult websites.

These cybercriminals seem to have a clever method of keeping their operations online. If this month they’ve registered domains such as,, or, a few months ago they registered domains hosted on the .in TDL.

Each of the domains is active only for a short period of time and all their names appear to follow this pattern of six random characters.

One interesting connection between all these domains appears to be Finland. The .in domains all ended up registered by someone apparently from Finland and the .eu registrant’s language was set to Finnish.
