What is Trojan Virus
Table of Contents

In the vast and complex world of cybersecurity, there are various types of malicious programs that can wreak havoc on our computers, networks, and even personal lives. One such type of malware is the infamous Trojan virus. Derived from the Greek mythological story of the Trojan Horse, this type of Trojan has been a prominent player in the realm of cyber threats. In this blog post, we will delve into the origins of the Trojan horse virus, explore its characteristics, examine different types of Trojan viruses, discuss ways to protect against Trojan infections and touch upon Trojan virus removal methods.

The Origins: Trojan Horse Virus

To understand the Trojan virus, we must first take a journey back to ancient Greece. The tale of the Trojan Horse comes from the famous city of Troy, which was under siege by the Greeks during the Trojan War. In a clever ruse, the Greeks built a large wooden horse and presented it to the Trojans as a peace offering. Unbeknownst to the Trojans, the horse concealed a select group of Greek soldiers. Once the horse was brought inside the city walls, the soldiers emerged during the night, opening the gates of Troy to allow the Greek army to enter and conquer the city. This story serves as the inspiration for the modern-day Trojan horse virus.

Characteristics of a Trojan Virus

Similar to its namesake, a Trojan virus disguises itself as something harmless or desirable, tricking users into unknowingly installing or executing it. Unlike other types of malwares that can replicate themselves, Trojans do not have the ability to self-replicate. Instead, they rely on social engineering tactics to convince users to willingly download and run the malicious program.

Trojans can infiltrate computers through various means, including email attachments, compromised websites, or software downloads from untrustworthy sources. Once inside the system, the Trojan may perform a range of malicious activities, depending on its specific design. Some common actions performed by Trojans include stealing sensitive information, such as login credentials or credit card details, logging keystrokes, recording screenshots, or even granting unauthorized access to the infected computer, effectively creating a backdoor for hackers.

Types of Trojan Viruses

Trojan viruses come in various forms, each with its own set of objectives and methods. Here are some of the most prevalent types:

Banking Trojan

This type of Trojan is designed to steal personal banking information, such as usernames, passwords, and credit card details. It often targets online banking customers, manipulating transactions or conducting unauthorized transfers.

Trojan Viruse

SMS Trojan

Operating primarily on mobile devices, SMS Trojans send and intercept text messages without the user’s knowledge. These messages can contain premium rate numbers, resulting in unexpected charges on the user’s phone bill.

Downloader Trojan

As the name suggests, this Trojan’s main purpose is to download and install additional malware onto the infected computer.  It often disguises itself as a legitimate program or file, making it difficult to detect and remove.

Downloader Trojans can enter your system through various methods, such as email attachments, infected websites, or peer-to-peer file-sharing networks. They can also exploit vulnerabilities in outdated software or operating systems.

Backdoor Trojan

This type of Trojan creates a hidden entry point, allowing hackers to gain unauthorized access to the infected computer. Once inside, they can perform various malicious activities, such as stealing data, launching further attacks, or using the compromised system as part of a botnet.

Protecting Against Trojan Infections

Prevention is always better than cure when it comes to cyber threats. Here are some effective measures to protect against Trojan infections:

Use reputable antivirus software

Ensure that your computer has a reliable antivirus program installed. Update the software regularly and schedule system scans to detect and remove potential Trojan viruses.

Exercise caution with email attachments

Be cautious when opening email attachments, especially from unknown senders or suspicious sources. Even if the attachment appears legitimate, it may contain a Trojan virus. Scan attachments with antivirus software before opening them.

Beware of social engineering

Trojans often employ social engineering tactics to deceive users. Be sceptical of unexpected emails, messages, or requests that seem out of the ordinary. Avoid clicking on suspicious links or sharing personal information unless you can verify the legitimacy of the source.

Keep software up to date

Regularly update your operating system, web browsers, and other software applications. Software updates often include security patches that can help prevent vulnerabilities that Trojans might exploit.

Practice safe browsing habits

Avoid visiting untrustworthy websites or clicking on suspicious ads. Stick to reputable and secure websites when downloading software or files.
