Tell us your computer virus horror story. The DNS is a vital support for how people interact with the internet, and many services like email or internet browsing would be severely crippled without it. Each server progressively holds a greater share of internet addresses, eventually reaching up to the primary 13 root servers that have access to every domain in the world.
In the indictment outlining the plan, the company was said to have used several elements to pull off the scheme. First, the false DNS servers were set up and opened an alternative route for computers to connect to the internet, as opposed to a user's own Internet Service Provider's DNS server. In the second step, the indictment says the members of the team, one of whom is still at large, developed and disseminated DNSChanger, a tool that changed the infected computer's default DNS servers to route to the false ones when browsing the internet.
When a user would enter the alphanumeric name for a site through their web browser or search engine, the fake DNS server that the virus rerouted the request to would provide an alternate IP address that led to a different website. In the case of the former, the servers redirected requests from users who had intended to go to the IRS website, and in the latter, users had wished to go to the iTunes store.
As the IP address generally remains hidden by most web browsers, a typical user wouldn't know why or how they were sent to a different online location than the site they originally intended to visit. However, the fraud was only conducted for certain websites, allowing some other requests to continue on the DNS chain undisturbed. This made the manipulation harder to detect. Visit the New Facebook.
