What is a Trojan Horse?
The name of the Trojan Horse is taken from a classical story of the Trojan War. It is a code that is malicious in nature and has the capacity to take control of the computer. It is designed to steal, damage, or do some harmful actions on the computer. It tries to deceive the user to load and execute the files on the device. After it executes, this allows cybercriminals to perform many actions on the user’s computer like deleting data from files, modifying data from files, and more. Now like many viruses or worms, Trojan Horse does not have the ability to replicate itself.
For example:
There was a Trojan that disguised itself as a game. Many users have downloaded this game and that secretly turned into a self-replicating virus. The game was a simple theme-based game, but it started to back up all the files on the drive where the user would access them. The Trojan turned out to be harmless, and it was easy for them to fix. So this was identified as Trojan because it did not disclose the virus.
Now after this many Trojan viruses or Malware came which turned out to be a threat or the most popular malware attack. As these Trojans can be found as versatile, this is used by many online criminals for malware attacks. The Trojans are a bit tougher to be identified. Trojans can be found in MP3 songs that the user may have downloaded, downloading games from an unsecured website, or advertisement that pops up when the user is browsing the page.
Many people have been infected by Trojans without realizing it. This type of Trojans is called Direct-Action-Trojans. It can’t spread to any user because when a virus infects the system show some indications that it has been affected by the virus.
Another example there is a direct action Trojan name Js. ExitW. It can be downloaded from many malicious sites. The effect of the Js. ExitW is to make the computer fall into a never-ending loop of start and shutdown. The Trojan does not do any damage which could be considered dangerous. But we should be aware that there are many Trojans that are far more dangerous.
