The term Trojan actually has a much wider meaning than just computer viruses. A Trojan can be any program that performs a function that is different from what the user expects, or it can be something like a virus or other malware. Essentially, any program that runs on your computer without your permission is considered to be part of this category.
What Is a Trojan Horse
The term “Trojan Horse” is derived from the Greek legend of the Trojan War. In the story, the Greeks were besieging the city of Troy for ten years. They had built a huge wooden horse, which they pretended was a gift for the Trojans.
The Trojans took the horse into their city, not knowing that it was full of Greek soldiers. At night, the soldiers emerged from the horse and opened the city gates, allowing the rest of the Greek army to enter and sack the city.
The term “Trojan Horse” has come to be used as a metaphor for any hidden danger or threat. It is often used to describe a situation where something seems harmless or even beneficial, but is actually harbouring a destructive force.
A Trojan horse is a type of malware that is designed to trick users into thinking it is a legitimate program or file. Once installed, the Trojan horse can give an attacker access to your system and allow them to steal sensitive information or wreak havoc on your system.
Trojans are often spread via email attachments or downloads from websites. Be careful when opening email attachments or downloading files from the internet, as you could unwittingly install a Trojan horse on your system.
Most Common Types of Trojans
Trojans are one of the most common types of malware. They are usually spread through email attachments or by downloading infected files from the internet. When a Trojan is executed, it can do anything from downloading other malware to stealing sensitive information. Trojans are often used to create botnets, which are networks of infected computers that can be used for malicious purposes.
1. Backdoor Trojan
The backdoor Trojan opens a backdoor on the target computer. This type of malware is used by attackers to access the victim’s system and provide them with remote access to it. Backdoor Trojans can be used for many different purposes, including stealing information, installing other malware or viruses, etc.
2. Remote Access Trojan (RAT)
A remote access trojan, or RAT, is a type of malware that allows an attacker to gain remote control of a victim’s computer. RATs are typically spread through email attachments or malicious websites, and once installed, they can give the attacker full control over the victim’s machine.
RATs can be used to steal sensitive information, install additional malware, or even take control of the victim’s webcam and microphone. RAT are a serious threat to both individuals and organizations, and there are a number of steps that can be taken to protect against them.
First, users should be vigilant when opening email attachments or clicking on links, and only do so from trusted sources. Additionally, organizations should have security measures in place to detect and block RATs, and users should keep their anti-virus software up-to-date.
3. Downloader Trojans
Downloader Trojans are a type of malware that download and install other malicious software on an infected computer. They are usually spread through email attachments or by visiting infected websites.
This trojan only work when you connected to the internet. Once installed, the Trojan will download and install other malware, such as viruses, spyware, and adware, on the infected computer.
This can cause the computer to become sluggish and unstable. In some cases, the Trojan may also steal personal information, such as passwords and credit card numbers.
4. DDoS Trojans
A DDoS Trojan is a type of malware that allows attackers to take control of a victim’s machine and use it to launch distributed denial of service (DDoS) attacks. DDoS attacks are a type of cyber attack in which the attacker attempts to overload a server or network with traffic in order to disrupt its normal operation.
Trojans are typically spread via email or instant messaging, and can be used to launch DDoS attacks against a wide range of targets. While DDoS attacks can be launched using a variety of methods. DDoS Trojans are a particularly effective weapon in the attacker’s arsenal.
This is because Trojans allow the attacker to take control of a victim’s machine and use it to launch the attack, essentially turning the victim’s machine into a “zombie” that does the attacker’s bidding. This can be done without the victim’s knowledge, making it difficult for them to defend against the attack.
DDoS Trojans are a serious threat to both individuals and organizations, and can cause significant disruption and damage. If you suspect that your machine has been infected with a DDoS Trojan, you should contact a security professional immediately.
5. Fake AV
The most common type of Trojan is Fake AV(Antivirus), which claims to be a legitimate antivirus program. A fake antivirus program is also known as rogue security software. Because it’s not actually an authentic piece of software and can do anything from hijacking your browser to stealing money from your bank account.
There are many fake antivirus trojans in circulation. They are often created by malicious individuals or groups in order to trick people into downloading and installing them.
These fake antivirus programs usually claim to be able to scan your computer for viruses and then remove them. However, they are actually just malware in disguise and will often infect your computer with viruses or spyware instead.
If you encounter a fake antivirus program, do not download or install it. Instead, report it to the relevant authorities so that they can take action to remove it from circulation. Be sure to also warn your friends and family about these fake antiviruses so that they don’t fall victim to them either.
6. Spy Trojan
Spy Trojans are malicious software that are designed to steal sensitive information from a computer. They are often used by cyber criminals to steal passwords, financial information, or other confidential data.
They can be used to collect information about the user and their behavior, or they may be used to track them in an attempt to gain access to their computer.
Spy Trojans can be installed on a computer without the user’s knowledge, and they can be very difficult to detect and remove. If you suspect that your computer has been infected with a Spy Trojan, you should seek professional help to remove it.
7. Game-Thief Trojan
There are a number of game-thief Trojans out there that can steal your hard-earned game progress and even your in-game currency. These malicious programs can be installed on your computer without your knowledge, and can run undetected in the background while you’re playing your favorite games.
Once they’re installed, they can record your keystrokes and mouse clicks, and send this information back to the hacker who installed them. This gives the hacker a clear view of everything you’re doing in the game, and can use this information to steal your account or progress.
These Trojans can be difficult to detect and remove, but it’s important to be aware of them and take steps to protect yourself. Be careful when downloading new games or game updates, and only download from trusted sources. If you think you may have a game-thief Trojan on your system, run a scan with a reliable anti-malware program to remove it.
8. Banking Trojans
Banking trojans are one of the most common and dangerous types of malware. They are designed to steal your banking login information and can cause a lot of financial damage.
Banking trojans usually come in the form of a fake banking app or a malicious website. They can also be spread through phishing emails or infected attachments.
Once the trojan is installed on your device, it will start collecting your login information and sending it to the cyber criminals. Banking trojans can be very difficult to detect and remove.
If you think you may have been infected, it’s important to run a security scan and contact your bank immediately.
That’s all the types of Trojans I could think of. If you have any other questions, feel free to reach out in the comments below. I hope this article was helpful for you and your family!
