Typically a Trojan virus will be designed to provide some form of remote access to a hacker or criminal on an infected computer. Once the Trojan virus has been installed the hacker will be able to perform tasks on the computer based on the user’s account privilege level. Some of these actions could be: to steal the user’s login and password data, credit card information, or bank account data; using the computer to conduct a denial-of-service attack against another user, company, or organization; installing other software to include additional computer malware; download or upload files on the user’s computer, log keystrokes or take screen captures of sensitive websites; crash the user’s computer; and to web surf in an anonymous fashion. Hackers do not have to directly distribute Trojan viruses; however, as many of the better known malware is designed to infect a computing system and respond to remote commands from hackers who did not originally deploy the malware. The hacker can conduct a scan of computers on a target network and once finding computer’s infected with the desired Trojan virus issue follow-on commands to control the computer.
