Don’t Get Knocked Offline With DNSChanger!

with one comment

Heads up: Krebs On Security is reporting that the DNSChanger Trojan horse virus is still in 12% of the Fortune 500!

On July 9, any systems still infected will be “summarily disconnected from the rest of the Internet.”

Click to enlarge. The U.S. government’s “safetey net” for the DNSChanger virus will go offline on Monday, July 9, which could see thousands could lose access to the Internet that once infected approximately 4 million computers across the world. The Federal Bureau of Investigation first gave details about the virus last November, which affects computers’ abilities to correctly access the Internet’s DNS system — essentially, the Internet’s phone book. The virus would redirect Internet users to fake DNS servers, often sending them to fake sites or places that promoted fake products.

The attached infographic provides some of the key background and history, but now the question is, what to do about it?

PC World explains DNSChanger rerouted infected computers through servers controlled by a criminal ring based in Eastern Europe, by basically hijacking the DNS service.

If you’ve been infected and recently visited Facebook or Google, PC World explains, you’ve likely seen a warning. But to be sure, check out this tutorial to see if DNSChanger has infected your PC (Mac or Windows).

There’s also a list of removal tools here you can use to learn more and prevent your systems from going offline on July 9th!
