Malware Monday: 60,000 DNSChanger Victims Could Go Offline


–> Check your computer go to dns-ok.us Green is OK. Red is not.

For thousands of computer users, the Internet will end on Monday July 9th due a nasty computer Trojan call DNSChanger. DNSChanger is a virus that changes a computer’s Domain Name Server (DNS) settings to point to bad servers put in place by hackers to steal personal information and generate illegitimate ad revenue.

DNS is the way websites manage names for access on the Internet, it allows users to type names into a Web browser like www.politic365.com and automatically find that address on the Internet.

Various news sources reported from 2007 until the six Estonian hackers were apprehended in November 2011, more than 14 million dollars was generated with the use of DNSChanger.

After the FBI, in “Operation Ghost Click,” busted the hackers last November, the FBI set up temporary servers to keep the computers infected with the Trojan temporarily online so users could clean them.  They decided on July 9, those servers would be decommissioned.

At this point, the FBI estimates about 300,000 computers worldwide remain infected, with about 65,000 of those being in the U.S. Those numbers has reduced exponentially from the originally figures from last year

To find out if your computer is infected with the DNSChanger malware, go to dns-ok.us or the DNSChanger Working Group to view an image with a green background if you’re clean or a red background if your system is in fact infected.

The above sites also provide vital information on how you can remove DNSChanger from your system if you are infected with the malware.

Facebook, Google and a few other online services have been notifying users who have DNSChanger malware on their systems.

Let us know if this has helped you.
