Could Your Computer Quit Working on July 9?

You may begin to hear about a “Doomsday” Internet threat that is scheduled to happen on July 9th.  There is an excellent article on the Sophos website that describes the problem, but basically, here is the situation.

Cyber-criminals set up several rogue DNS servers on the Internet.  DNS servers find the IP addresses of web site URLs (such as and help your computer to connect the the correct website.  If your computer, DSL Modem, Cable Modem, or Wireless Access Point was changed to use these servers, your browser would be connecting you to web sites that the cyber-criminals wanted to send you to, instead of the site you requested.

The FBI and Interpol seized these DNS servers in November 2011.  Rather than turn them off immediately, they cleaned up the malicious code, and have been running them at a cost of about $90,000 so far.  They are turning them off on July 9th, so now is a good time to find out if this is a problem for you.  Otherwise, the Internet will be “unavailable” to you after July 9th.

There is an FBI website where you can check your DNS server to see if it is one of the problem servers.  You will need to run an ipconfig /all from a command prompt to get the IP addresses of your DNS servers.  There are instructions on the FBI site.

If you are infected, you will need professional assistance to resolve the problem, as the DNS information may be in your computer, DSL or Cable modem, or Wireless router, and these last three may be hard for you to access on your own.  Of course, WyzGuys would be our recommendation for professional help.
