Definition of Trojan

Let’s begin with a narrative. The Greeks constructed a massive wooden horse and hauled it to the city of Troy’s gate during the Trojan War, which took place more than 3,000 years ago. It was viewed by the Trojans as a gift and a battle trophy signifying their triumph.
They were unaware that a group of Greek troops were concealed inside the wooden horse. The Greeks fled the city as the horse was dragged inside, unlocked the gate for the other forces, and demolished it.
The way Trojan horses operate in computers is precisely the same: they pose as something they’re not in order to infiltrate your system and attack your machine. Hackers deceive individuals into downloading malware using a variety of social engineering approaches, and their strategies become more complex every year.

What distinguishes a virus from a Trojan horse?

It’s common to refer to a Trojan as a virus, although that’s not exactly accurate. A Trojan horse cannot duplicate itself or distribute its copies, however a virus can. A Trojan horse is technically a kind of malware.

Trojan software may alter your data, capture your keystrokes, steal your passwords, and even download further dangerous applications silently. While some Trojans wait for commands from a hacker, certain Trojans begin their malicious activities as soon as they enter your machine. A computer that has been taken over can be used to launch DDoS attacks and build a botnet.
A Trojan horse may be inadvertently downloaded when you install an application or when you open a malicious email attachment. It may take some time for some folks to discover that anything is wrong and that they have an unseen visitor on their device.

3. Trojan downloader
   The sole purpose of these Trojans is to infiltrate your system and then download further software.
4. DDoS malware.
   A DDoS assault involves flooding a target network, server, or service with a massive volume of traffic, which brings down the system.

DDoS Trojans are only concerned with adding additional “zombie” troops to the botnet army so a hacker can amass sufficient funds to conduct an assault.

8. Trojan GameThief.
   Due to the enormous demand for online gaming accounts on the dark web, fraudsters create Trojans to steal user passwords.

How to defend against a Trojan

Nobody can completely protect themselves from Trojan horses, and anybody might become a victim of crime. However, you may reduce your chance of contracting an infection by using certain software and good judgment. Here are some tips on how to safeguard yourself against Trojans and other malware:

1. Always do timely software updates. Hackers frequently take advantage of software flaws as engineers work to fix them. A criminal can infect you if you put off updating because of a security flaw that was resolved months ago.
2. Never click on a dubious link in a text or email. The main way to infect your device with malware is through phishing emails. Never click on links unless you are familiar with and confident in the sender.
3. Do not open attachments. Even though email attachments are frequently used to spread malware, many users fail to pass this test.
4. Don’t visit torrent sites. Avoid utilizing torrenting websites since you may never be sure what you will acquire there. Malware sometimes comes combined with other programs or files. Rely only on authorized app shops.
5. Make your passwords special. It is strongly advised against using the same password for all accounts. Use uppercase, lowercase, special characters, numerals, and a combination of all of these in your passwords.
6. Make two-factor authentication available. Use two-factor authentication wherever possible since it will provide your accounts an extra degree of protection.
7. Put antivirus software to use. Although the majority of gadgets come with built-in security software, having a second antivirus program is absolutely not a bad idea. The Threat Protection feature of FreeZone VPN is also quite useful since it enables you to discover malware-infected files, prevents you from visiting hazardous websites, and immediately eliminates trackers and annoying adverts.
8. Avoid dodgy websites at all costs. If a website starts to annoy you with odd advertisements, exit right away. A single unintentional click might result in a swarm of Trojan horses or adware.
9. Before using external devices, scan them. Always do a security scan before using a USB or external drive since it is common for malware to spread from one device to another through these methods.
10. Apply a VPN. Your security is increased with a virtual private network, which masks your IP address and encrypts your internet data. Given that hackers can create a phony hotspot and remotely infect your device over public Wi-Fi, it is particularly helpful.
