Polish CERT acts against Virut malware with domain takedowns
CERT Polska, a computer emergency response team in Poland that is run under the aegis of the country's Research and Academic Network (NASK), has announced takedown action against a raft of web servers associated with the Virut family of malware.
Most zombies rely on connecting to so-called C&C (command-and-control) servers to find out what to do next.
So taking over some or all of those servers can make a big difference, at least temporarily, to the crooks' ability to operate their botnets. Every infected PC that crooks can no longer send on a criminal mission represents lost opportunity and lost revenue, and that hits them where it hurts: the pocket.
