A Trojan, in the world of computers, is a type of malware. The term “Trojan” is short for “Trojan horse,” inspired by the ancient Greek story of the wooden horse used to deceive the city of Troy. Just like the wooden horse, a Trojan in computing tricks users into believing it is something useful or harmless, while it actually causes harm.
Things You Should Know About Trojan
You may hear the story of the Trojan Horse, think of it as a sign of wisdom or victory. If you are good at computers, a trojan may be known as a kind of computer virus.
The Mythological Trojan Horse
The concept of a Trojan horse comes from Greek mythology. The Greeks tried to get into Troy but couldn’t break the strong walls. So, they built a big wooden horse and hid soldiers inside. They left the horse at Troy’s gates and left. The Trojans thought it was a gift and brought it inside. At night, the soldiers came out and let the Greek army in, causing Troy to fall. This shows how something innocent can hide a danger.
What is a Trojan in Computing?
In computer security, a Trojan is a malicious software program that pretends to be something useful or legitimate. It usually arrives disguised as a game, utility, or even an email attachment. Once installed, it can steal personal information, damage files, or give hackers control over your computer.
Unlike viruses or worms, Trojans do not replicate themselves. They rely on tricking the user into installing them.
How Trojans Spread?
Trojans are often spread through fishing emails, fake software updates, or infected downloads.
Trojans are designed to stay hidden. They often run in the background without showing any obvious signs of their presence. A Trojan often disguises itself as a useful or legitimate program. It might come as an email attachment, a download from a website, or even an app.
When you open the infected file or install the software, the Trojan is secretly installed on your computer. It might not show any signs at first. Once installed, the Trojan can perform various harmful actions. It might steal personal information, monitor your activities, or even give hackers control over your computer.
For example, you might receive an email with an attachment that seems to be a document or a photo. If you open this attachment, you might unknowingly install the Trojan on your computer. Trojans can also be hidden in downloadable software or games.
Why Are Trojans Dangerous?
Trojans can be very dangerous for several reasons:
1. Data Theft: Trojans can steal sensitive information, such as passwords, credit card numbers, and personal files. This information can be used for identity theft or financial fraud.
2. System Damage: Some Trojans can damage your computer’s system files, making it run slowly or crash. This can lead to data loss and costly repairs.
3. Unauthorized Access: A Trojan can give hackers access to your computer. They can use this access to install additional malware, steal data, or cause other harm.
4. Spread of Malware: Once a Trojan is on your computer, it can spread to other devices on the same network, increasing the damage.
Because of these risks, it’s important to use reputable security software, keep your systems updated, and be cautious about downloading and installing software from untrusted sources.
