If You Lose Internet Access Next Monday, Here’s Why

July 5th, 2012

Computer SecurityThe DNSChanger trojan infected hundreds of thousands of computers worldwide and changed their DNS server settings to point to rogue servers. (Your DNS setting tells your computer where to go to look up a URL such as www.chadsnews.com. Without one, you’re effectively shut off from the Internet.) The FBI shut down the source of the malware but realized that turning off those rogue servers would have severe effects for those who were infected—they would lose Internet access. So as a stopgap measure, the FBI set up real DNS servers to replace the malicious ones. This Monday (July 9th), however, the FBI is going to permanently turn off those servers.

The FBI has a webpage with instructions on how to determine if your computer is infected. I suggest taking a few minutes now to verify that your DNS is okay. If you’re infected, and even if you’re not, this might be a good time to consider using OpenDNS as your DNS provider.
