Trojan.Hosts.6815 is one of the many variants of a category of Trojans known as Trojan.Hosts. The Trojan.Hosts.6815 variant is the most prevalent in these kinds of attacks recorded in 2013. Trojan.Hosts.6815 (like other Trojans in this category) is designed to affect the Windows HOSTS file, which determines how a computer connects to the Internet. By altering this file, criminals can force computer users to visit predetermined websites in order to carry out various kinds of malware attacks and online scams, ranging from exposing computer users to advertisements all the way to destructive forms of malware delivered by dangerous exploit kits located on attack websites specifically designed to exploit flaws and vulnerabilities in your computer's security. Removing a Trojan.Hosts.6815 infection will often require replacing the affected HOSTS file or reverting all harmful changes, a task that can often be done automatically by some anti-malware programs.

How Trojan.Hosts.6815 Affects Your Computer

Computers, when connected to the Internet, are identified by their IP address. This includes servers containing the websites to which computer users connect when browsing the Internet. The IP address is equivalent to the 'telephone number' you would dial to connect to a particular website. However, to connect to websites computer users will usually use the website's domain name, which is more practical, easy to remember and user friendly. Because of this, there are DNS (Domain Name Servers), servers that have the function of matching domain names to IP addresses and routing you to the website you want to reach. The Windows HOSTS file contains the information needed to connect to the DNS which then leads your computer to the website you want to visit. By altering this file, Trojan.Hosts.6815 can force your computer to visit a rogue DNS server or to visit a specific website directly, giving them the power to control where your Web browser goes.

How Trojan.Hosts.6815 is Used to Steal Money and Carry Out Online Scams

Once criminals are capable of routing your online traffic by making you visit specific websites, they can make money off of this in a number of ways. Some examples include the following:

  • Creating attack websites that will attempt to install Trojans, viruses and worms on all visitors' computers.
  • Forcing you to visit websites that are composed of little more than advertisements.
  • Creating websites that will be designed to look exactly like the log-in screen for online email services or social media websites in order to trick computer users into entering their password and log-in details.
