Some Users May Lose Internet Access Monday

Efforts to eliminate a high-profile Trojan may cause some Internet users to lose connectivity on Monday. And, getting systems back up and running may be far more difficult than the preventative measures themselves.

The Federal Bureau of Investigation will be shutting down servers used by operators leveraging the DNSChanger Trojan, and when that happens, people with infected systems will lose access to the Internet. About 64,000 users in the USA are still infected.

A DNSChanger Trojan literally changes the infected computer’s DNS settings. When a user opens up a browser and enters a web address, good DNS settings will take you to the proper website. But if you’ve got malicious DNS settings, the criminal can point you to whatever server they want. So it can be used in a lot of nasty and malicious ways. The FBI has taken control of a lot of these malicious servers, and on July 9th, they are going to shut down all of these servers. That means if you open up your browser and you are infected with this malware, you won’t be able to get to the Internet because it won’t be able to resolve your DNS to the correct addresses or anything else.

That translates to users not only losing web and email access but also connectivity to resources that will restore their services without on-premise support.
