DNS Malware to Knock Hundreds of Thousands of PCs Offline Monday

Paul Lilly

Back in November 2011, the FBI and NASA-OIG worked with Estonian police to arrest a band of cybercriminals known as "Rove Digital" who were operating a botnet that would alter user DNS settings to point infected systems to malicious DNS data centers in Estonia, New York, and Chicago. Come Monday, the Internet will go dark for potentially hundreds of thousands of unsuspecting PC users unaware their system is infected with a DNS changing virus.

It's believed that at least 277,000 PCs are still infected, and possibly many more, according to an AP report . Due to the number of infections, the Internet Systems Consortium agreed to operate replacement DNS servers for the Rove Digital network so users of infected systems could surf the Web as usual. On July 9 at precisely 12:01am EDT, that temporary safety net will shut down.

Many users of infected systems don't even know their PC has been compromised, but they'll find out on Monday when the Internet goes dark. To prevent being one of them, there are various steps you can take to check if you're infected, one of which includes simply clicking on a hyperlink .
