Fake DHCP server sends your requests to cybercrime ring
The online word has become the center of the real world and the impressive number of domains (web addresses) registered since 1985 has surpassed the 200 million mark. More to the point, there are 133,025,573 active Internet domains registered worldwide ? an impressive figure that offers you a glimpse of the resources you could visit, if you wanted.
Domain names allow us to represent web addresses (IPs) in a form that is easy to remember and access from your browser. Rather than typing 66.132.220.42, you can just ask the browser to point you to bitdefender.com. The DNS system will convert your domain name (bitdefender.com) into an IP that can be interpreted by the computer. Succinctly put, the DNS system is similar to a phone directory ? you know who you want to call, but you don?t know their number. It is an essential part of the web that has been targeted a lot by cyber-criminals and, if compromised, chaos breaks loose.
As the DNS infrastructure is well defended against attacks, cyber-crooks often try to mess with the local DNS settings. This is the case of the infections with Worm.Rorpian.E that, once it successfully infects a computer on the network, starts acting as a DHCP server (an application that manages the connectivity of the network computers) and tampers with the local DNS servers to resolve all the requests to a rogue IP in Romania.
