The Trojan horse is a popular and one of the most common types of malware we often hear about everywhere.
According to McAfee, malware in the form of a Trojan horse is a file, program, or section of code that masquerades as genuine and risk-free when, in reality, it is malicious.
In Greek mythology, a Trojan is a hollow wooden horse that the Greeks hid inside during the Trojan war. This wooden horse was a bait to Trojans, deceiving them it was a gift. When the wooden horse entered the walled city, this was the perfect chance for Greeks to come out and attack while people were sleeping.
Just like the wooden horse, trojan malware deceives users by pretending to be legitimate software or sometimes attached files or in a form or emails. Once you open and install it successfully, it can control your computer and obtain data. This can happen to smartphones and laptops as well.
Many Trojans will also download further malicious software after being installed on your computer. A trojan is a software programmed to injure, disrupt, steal, or inflict any other activity that could be considered damaging to your data or network.
Trojans come in a wide variety of flavors, the most common of which are banking Trojans, backdoor Trojans, DDoS Trojans, dropper or downloader Trojans, exploit Trojans, fake antivirus Trojans, Trojan-GameThief, Trojan-Ransom, and many others besides.
Trojan horses are a form of malware, but they are not the same thing as viruses. This is because viruses and Trojans infect their victims in fundamentally different ways. As opposed to viruses, which may replicate themselves and spread from one host to another, Trojans require human intervention to be installed.
