Hundreds of thousands of Internet users worldwide could be without Internet access by Monday morning due to a clever Estonian-engineered malware virus.
The DNS-Changer software was created by a ring of Estonian criminals. The group engineered the malware to redirect user computers from the domain-name-server they chose to rogue servers manufactured by the miscreants. As an example, a user attempting to pull up iTunes might be directed to a fraudulent website selling Apple products. Another might simply see fraudulent advertisements. According to the FBI, it will be almost impossible for average users to tell if they have been infected. Feds shut down the crime ring in November 2011 but unfortunately the DNS-Changer malware has proved a lot harder to stomp out.
The FBI estimates that the DNS-Changer now affects around 275,000 computers worldwide. To buy Internet providers some time, the FBI provided a temporary fix by re-routing the fraudulent traffic, but that fix will be shut off at 10 p.m. Sunday, July 7, Mountain Time, meaning users whose ISPs haven't managed to inform their customer of the infection could be in for a very inconvenient start to their work week.
