Apple recently asked a web registrar, Reggi.ru, to shut down a domain belonging to the Russian security firm Dr. Web, the latter company's CEO has revealed. Boris Sharov says the registrar informed him about the request on Monday. Apple's reasoning was that the domain was being used as a command-and-control server for computers infected with the Flashback Trojan. Sharov notes, though that the domain is actually hosting a "sinkhole," a spoofed C&C server used to monitor computers linked in the Flashback botnet.
