Tomorrow Might Be Your Last Day On The Internet: DNSChanger Malware and How it Works

Posted by on July 7, 2012 at 4:07 pm

I don’t want to alarm you or anything, but tomorrow may be your last day on the internet! Don’t worry, the world isn’t ending, but you may be infected with malware. This malware was so smart, smart and sneaky, because it changed your DNS server to point to rogue DNS servers. Luckily for the world, the FBI found these rogue DNS servers in Operation Ghost Click, which is an awesome sounding operation!

This happened back in November 2011 and the FBI has been maintaining these rogue DNS servers BUT with them fixed so it wouldn’t affect anyone else. The FBI is tired of running these servers and will be turning them off on Monday, July 9, 2012 and if you’re infected you won’t be getting to websites.

So how does this all work? Well, anytime you type a URL into your browser like your computer contacts a DNS server for it’s IP address which is owned by a server (computer) somewhere in the world. Then your browser goes to that server and says, excuse me, I’m looking for, can you tell me where I can find them? The server says, sure, this way and then you see the website. This all happens in a matter or seconds or even less.

What the rogue DNS servers did were telling your browser the wrong IP address so it would then go to a wrong server who would then pretend to be whatever website you were looking for or sometime even redirecting you to the right website but only after showing you pop-ups or trying to install more malware on your computer. It’s a nasty, nasty thing.

All you need to do is go to this website,, if you are infected with the wrong DNS servers and if you are they will let you know how to correct the issue. If you see green you are good to go!
