What Is A Trojan Horse?

A Trojan Horse (or just Trojan) is a destructive program is another type of malicious software or code that seems to look as legitimate as it seems but don’t get fooled, it can take a full control of your personal computer. It has been designed to steal, disrupt, damage or over-all, inflict harmful action you can imagine on your network or data.

How Exactly Does A Trojan Horse Work?

Imagine yourself receiving an email from a friend close to you, someone that you trust. You checked on it and you found an attachment that seems to be legitimate, so you downloaded the file.
Unfortunately, from that very moment, you fell into the trap. The email is actually not coming from your friend but from a cybercriminal that was successful enough to attack your friend’s email and spread the virus. The file that you clicked, downloaded and even opened is actually a fake version of an app that is loaded with malware and is now going to begin installing malware onto your device. Take note that Trojans don’t only attack desktop computers and laptop, but they can as well impact mobile devices, such as tablets and cellular phones.

The moment you execute this program, you are already giving authority to the malware to spread damage to your computer or even steal information and commit different crimes. Just like how the Trojans allow the Greek soldiers to wreck havoc to their city the moment they let the horse in.

What are the damages it can cause? It varies since Trojan Horse has been designed to execute different things. You can check out below some of Trojan malware you will most commonly encounter, each has its own name and unique way of damaging your computer.

  1. Backdoor Trojan. This will open a backdoor for an attacker to get an access and control the victim’s system in the future. For instance, the victim’s data can now be easily downloaded and stole by any third party. What’s worse is that Backdoor Trojan paves way for more malware to be uploaded into your device.
  2. Exploit Trojans. These are malicious programs containing code or data that can take advantage of the vulnerability of an application software found in your computer.
  3. Distributed Denial of Service (DDoS) attack Trojan. These are programs that conduct Denial of Service or Dos attacks towards any targeted web address. This is made possible by transferring several requests from your infected computer which can beat the objective address and will then result to denial of service.
  4. Rootkit Trojan. This one’s the worse, its main purpose is to prevent you from discovering the malware that is already infecting your system, as a result, it will lead to maximum damage.
  5. Downloader Trojan. This comes in a file form that is written to transfer additional malware, which sometimes includes more Trojans, on your device.
  6. Data Sending Trojan. This will give the culprit sensitive information such as passwords including other information programs that can be hijacked.
  7. Remote Access Trojan (RAT). This is often found hiding in your favorite games as well as other smaller variety programs that allow the attacker to take control of your computer.
  8. Proxy Trojan. Since it is a proxy server, it will enable a criminal to hijack your computer and execute illegal activities from your computer.

How Can You Recognize, Detect and Get Yourself Protected from A Trojan Horse Virus?

Trojans are being used as delivery service for several various types of malware, so if you think that your device has likely been infected by a Trojan, then you should check out for some of the possible signs that you have been breached with this malicious software.

  • Poor performance of your device. Have you noticed your computer starts to run slowly or is now crashing more often than it normally does?
  • Your device is now behaving strangely. Have you noticed there are now programs in your device that start running even if you didn’t initiate it at all? Is your device starts executing unexplained processes?
  • Are you frequently interrupted with spams and pop-ups? Have you noticed there’s an increase in the uptick of interruptions that you receive in your browser from email spam or pop-ups?

If your computer is showing these symptoms, then there’s a big chance that a Trojan Horse has been successful enough to sneak its shipment onto your device. I suggest you search your device for any applications or programs that you don’t recall installing by yourself, then look for this unrecognized file names into the search engine to see if they are recognized as Trojans.
