Will Your Internet Access Be Cut Off on Monday (July 9th, 2012)?

By July 7, 2012

Follow me on:

The odds of you personally being affected are very small. However, an estimated tens of thousands of people around the world could have their Internet access effectively blocked on Monday when certain DNS servers are shut off. It all has to do with the fallout from a piece of malware named DNSChanger. If your network isn't infected by DNSChanger, this server shutdown has no impact on your Internet access. If your network is infected, however, the shutdown will cause your Web browsing to stop functioning. Fix it by changing your DNS settings to point to valid servers, either those maintained by your Internet service provider or by a third-party service like OpenDNS.

How can you tell if you're infected? Try using the www.dns-ok.ca Web site. More - Last Chance to Remove DNSChanger (cbc.ca)

DNSChanger is the name of an Internet trojan estimated to have infected millions of computers around the world. In a nutshell, DNSChanger (incorrectly reported in some outlets as "DNSCharger") redirects your Internet traffic to unsafe Web sites by modifying your computer's or router's DNS settings to point to malicious DNS servers. When the perpetrators behind the trojan were caught last year, the U.S. Federal Bureau of Investigations oversaw replacing those DNS servers with functional but temporary systems. Now the FBI is ready to shut down its temporary servers. It was to happen originally on March 8th, but the deadline was extended to this coming Monday - July 9th, 2012.

@ Mick… DNS = domain name server. When you type an address like http://www.about.com into your browser’s address window, your request for that webpage is routed to a domain name server. It’s a computer somewhere that converts your human typed “about.com” to the IP number for that website, which happens to be

@ Jim… NO FEDS protecting my Internet. I agree with you there, pal.

For better security run GNU/Linux. W32 DNSChanger will have no effect whatsoever on Linux systems. :)

Take care…

FBI controlling the internet? Surely you all don’t understand the enormity of such an undertaking. It would be like trying to empty the Pacific Ocean with a dixie cup!

Umm.. last I heard the FBI had sniffer racks at the majority of the ISP’s as it is.. And then we have SOPA – Stop Online Piracy Act which is the government (by means of the movie industry) to put up a China Like Firewall which would impede your browsing HUGE!!!

It is funny to see people’s ignorance. This was never about monitoring, or the FEDs protecting the internet.

Some cyber criminals had intriduced some malwhere that redirected people’s attempts to reach things on the internet to go through their servers. I suspect that they were using this rediection for some other purpose – perhaps capturing passwords or financial information.

The courts gave the FBI permission to replace these servers temporarily so that those with infected computers would not be cut off. That permission expired on July 12.
