Google to notify users on DNSChanger malware

From May 22 Google started its to notify roughly half a million people that their computers are infected with the DNSChanger malware.

It had successfully notified a million users last summer to a different type of malware, where they started showing warnings via special messages that would appear at the top of the Google search results page for users with infected devices.

The Domain Name System (DNS) translates familiar web address names into a numerical address that computers use to send traffic to the right place. The DNSChanger malware modifies DNS settings to use malicious servers that point users to fake sites and other harmful locations. It also attempts to modify the settings on home routers as well- may infect other computers and mobile devices also.

Since the FBI and Estonian law enforcement arrested a group of people and transferred control of the rogue DNS servers to the Internet Systems Consortium in November 2011, various ISPs and other groups have attempted to alert victims. However, many of these campaigns have had limited success because they could not target the affected users, or did not appear in the user’s preferred language (only half the affected users speak English as their primary language). At the current disinfection rate hundreds of thousands of devices will still be infected when the court order expires on July 9th and the replacement DNS servers are shut down. At that time, any remaining infected machines may experience slowdowns or completely lose Internet access.
