A Trojan, also known as the Trojan horse is a malicious script or code embedded into a software system or tool which ultimately looks legit but has gruesome intent hidden within its code. A Trojan might have a different approach with the final intent about what it is designed to do. Such as it might be that the Trojan is designed to damage, disrupt, steal, or inflict some sort of other harmful activities to your system or network.
Initially, a Trojan is not harmful at all until unless its executables are not run. But if somehow you get tricked into running or clicking on the install button of the application then you are in a lot of trouble. As the Trojan would install itself and get on to the work it was initially designed to do. Trojan can be transferred from one system to another or from a single network to many devices, but it can’t replicate or initiate the process on its own. A user has to run the executable in order for it to take the reins. It is important to know how this infiltration of the Trojan virus works and what you can do in order to move past it.
How does the Trojan work?
Trojans work pretty simply such as the phishing or social engineering traps work. In fact, it requires help from either the phishing side of social engineering to launch itself and reach a potential victim. Suppose that you received an email from someone with a dedicated attachment to it. Now, it looks legit and all but the attachment is not it is possible from a cybercriminal who is tricking you into installing the malware. You are safe until you don’t install the executable file and literally doom yourself into confronting the installation of malware into your system and from that possibly into the whole network.
The Trojan ultimately replicates itself and it does spread to the other files and data on your hardware. But the after action of the Trojan virus would be a little different than the others based on the coding or programming of the virus itself. Many Trojans perform different functions, that is why it is important to understand it through the following examples;

Backdoor Trojan
The backdoor Trojan opens a backdoor into your system which means that the attacker can download any particular file from your computer or upload more intense malware for further destruction.
DDoS Trojan attack
The DDoS Trojan automatically narrates into the DDoS attack by overflowing the website or network of the victim with ultimate traffic. The Trojan might enter the website or network from an infected device connected to it or surfing through the website.
Downloader Trojan
This is an advanced form of the Trojan which after getting installed doesn’t let go of the malicious activity. This type of Trojan would welcome other types of Trojan from the internet by allowing their downloading, other malware and adware would also be installed, just in case to trouble the user to its extreme.
Ransom Trojan
This type of Trojan would seek some kind of financial compensation or ransom in order to undo the damage it has already done to your system. This in the latest terms is called the ransomware, it might encrypt some of the most important files on your system and would impair other keen functioning of your system.
How to protect yourself from Trojans?
Trojans are extremely dangerous entities but still, these can be counterfeited and controlled in a progressive manner. Following are some of the tips that you can take on and the security methods that would automatically help you to stay secure from the Trojan virus;
- The security of your computer and networking can be boosted with the help of installing an anti-virus and anti-malware system. Running diagnostics and scans is the most verifiable method to unveil any irregularities or vulnerabilities that exist within your system.
- Don’t be shy on updates, always consider updating your current operating system or the software systems that you are currently using for the sake of staying secure on the internet at all times.
- Protect your identity on the internet, in-house, and everywhere by upgrading your passwords at all times. This way you will be more secure and relatively invisible on the internet. Using two-factor authentication is also a great way to stay secure on the internet.
- Back up your files onto the cloud or on separate hardware that doesn't need to stay connected to the internet or linked to your main system at all times.
- Don't download or install some software that you don't recognize or don't seem plausible to you.
- Don’t open an email address unless you know what it is about or can validate its original source.
