For Home View all Malwarebytes products. Trojan soldiers watch as the Greeks appear to sail away, leaving behind a giant wooden horse as a token of surrender.

Drunk on victory, the Trojans bring the horse inside their walls, only to discover Odysseus and his men were hidden inside the whole time. While technically they are not computer viruses but rather a separate form of malware, "Trojan horse virus" has become a common way to refer to them.

People sometimes think of a Trojan as a virus or a worm, but it is really neither. A virus is a file infector which can self-replicate and spread by attaching itself to another program. Most viruses are now seen as legacy threats.

Worms have also become rare, though they do pop up from time to time. Think of Trojans as an umbrella term for malware delivery, because there are various kinds of Trojans. Put another way, a Trojan is a delivery strategy that hackers use to deliver any number of threats, from ransomware that immediately demands money, to spyware that conceals itself while it steals valuable information like personal and financial data. Keep in mind that adware or PUPs potentially unwanted programs can be confused with Trojans because the delivery method is similar.

For example, sometimes adware sneaks onto your computer as part of a bundle of software. The program authors usually include the adware for marketing affiliate reasons so they can monetize their installer with offers—usually clearly labeled. Such adware bundlers are typically less malicious than Trojans. Also, they do not conceal themselves as Trojans do.

But since the adware distribution vector resembles that of a Trojan, it can cause confusion. Trojans can look like just about anything, from free software and music, to browser advertisements to seemingly legitimate apps.

Any number of unwise user behaviors can lead to a Trojan infection. Here are a few examples:. It presented itself as a simple game along the lines of twenty questions. However, behind the scenes, the game copied itself onto shared directories where other users could find it. From there, the game could spread across entire computer networks. For the most part, it was a harmless prank.

In the s, another infamous Trojan appeared disguised in the form of a simple Whack-A-Mole game. The program hid a version of NetBus , a program that allows one to remotely control a Microsoft Windows computer system over a network. With remote access, the attacker could do any number of things to a computer, even open its CD tray. As clever as the worm was from a technical perspective, its use of social engineering was arguably its most ingenious component.

Through the s, Trojan attacks continued to evolve, as did the threats they carried. In , a Windows-based backdoor Trojan horse called Beast emerged and was capable of infecting almost all versions of Windows. Then, in late , another backdoor Trojan called Zlob was distributed disguised as a required video codec in the form of ActiveX. The s also saw a rise in the number of Mac users, and cybercriminals followed suit. The motivations behind Trojan attacks also began to shift around this time.

Many early cyberattacks were motivated by a lust for power, control, or pure destruction. By the s, an increasing number of attacks were motivated by greed.

In , a Trojan named Zeus targeted Microsoft Windows in order to steal banking information by means of a keylogger. In , hackers released Torpig, also known as Sinowal and Mebroot, which turned off anti-virus applications, allowing others to access the computer, modify data, and steal confidential information like passwords and other sensitive data.

As cybercrime entered the s, the greed continued, but hackers started thinking bigger. Simply copy and paste the contents of that notepad here on your next reply.
