What Is A Trojan: The Latest Trend

It’ll come as no surprise to hear that a Trojan virus takes its name from the legend of the siege of Troy, hiding inside legitimate-looking - or in some cases, completely legitimate and unharmful - software to infiltrate a network and cause harm.

How Trojan Viras Damage

Just like the 2,500-year-old legend, where an invading Greek army hid in a giant wooden horse to fool the opposition, a Trojan virus can be extremely damaging. It may not be able to take down an entire city (or at least that would most definitely be a worst-case scenario), but it can certainly attack a business’ infrastructure from within and spread fast.

The malware camouflages itself as legitimate software to dodge any antivirus or other security system set up to resist attacks and then reveals itself when it’s too late and the malicious code has spread or completed its mission.


Trojan viruses can stay dormant for a while, spying on the user’s computer without any evidence of malice at all. However, it’s already plotting its next move at this point, which could be modifying data on a computer, copying information and sending back to its developer or even worse, blocking access to data or draining a machine of its computer resource.

There are lots of different types of Trojans and they’re named according to the type of attack they have been designed to carry out.

For example, Backdoor Trojans have been architected to control a user’s computer remotely. They are downloaded and installed like all other types of Trojan but give total control to the hacker using a backdoor attack. For example, then can allow the hacker to snoop around your computer’s files and systems, potentially stealing confidential data. If the hole isn’t closed, the hacker can continue to use it as a way to come back whenever they wish.

Download Trojans can be used to download and install other malware onto a machine. The most common malicious software are keyloggers, cryptocurrency miners and ransomware.

Banker Trojans-Horse

Banking Trojans are financially-motivated attacks. They hide on the computer, waiting for the user to head to a banking website but then divert them to a fake homepage, where they’re directed to enter their login details that the hacker can steal and use on the genuine banking website.

Some of the most well-known banking Trojans were Zeus, Dridex, and Kronos, although banks have now started cracking down on such attack and have heightened security, making these types of attacks less prevalent.

While Trojans can cause significant damage if loaded on someone’s system, there are ways to prevent malware from causing problems.

How To Prevent Trojan Virus Attacks

Simple steps such as avoiding unsafe websites and keeping accounts safe with secure passwords and firewalls can help prevent malware attacks. Updating a device’s operating system as soon as possible will also help prevent Trojans from causing damage as malware tends to exploit the problems in outdated software.

However, perhaps the most effective way of preventing this kind of malware attack is by installing anti-malware software on devices and by running diagnostic scans with this software periodically.
