Partly fact and myth but not to be taken lightly, Monday July 9th, 2012, some users will be affected by losing Internet connection. It is reported that over 300,000 user could lose Internet connection.
This issues stems all the back to 2007, when most users were using Internet Explorer 7 and Firefox 2. A malware called DNSChanger was the culprit and it worked by hijacking DNS settings that change the web address into an IP address, which allows surfing the web. This malware directs the intended address to be redirected to a fraudulent site instead. For example, if you were to try to purchase something from a website you intended, you would be redirected to a site where you would be ultimately robbed.
The FBI shut down the rogue DNS servers and now the US District Court for the Southern District of New York appointed Internet Systems Consortium, a not-for-profit company, to keep running replacement DNS servers so affected users would not loss Internet access before they could remove the botnet and fix their DNS settings.
