A Trojan virus is identical to the idea of the Trojan horse except instead of an army of men hidden inside, malware is concealed. There are different types of Trojan viruses but all have a similar end goal and are equally malicious.
The following are only a few examples:
- Backdoor Trojan. This type of virus silently enters through a “backdoor” it creates. Once inside, the virus allows a malicious actor full access and control to your device. From here, other dangerous malware can be downloaded and data can be stolen.
- Banker Trojan. After infiltrating and infecting your device, this virus specifically attacks banking information. Any and all financial accounts are targeted by this kind of virus.
- Rootkit Trojan. Silently hiding in your device for the maximum amount of time before being discovered is this virus’ overall goal. This allows the cybercriminal to inflict the most damage it possibly can.
- Game-thief Trojan. Through online games, this variety of Trojan virus looks to steal gaming account information.
- SMS Trojan. This Trojan works to attack text messaging. It can block, delete, or hide messages. It can also send messages and overuse data to run up phone bills.
What can you do to avoid an attack?
- Back up your device files. By having a copy of your files, you may not be able to stop cybercriminals from stealing data however, it will make restoring your computer much easier.
- Keep your software up to date. Updating your device with the latest improvements protects you from security vulnerabilities and patches up other holes in the previous software version.
- Be wary of suspicious sites. Avoid unsafe sites by verifying legitimacy. If something strikes you as odd, trust your gut and leave the website.
- Only open email attachments sent by trusted addresses. This is another common way Trojan viruses enter your device. Do not trust sketchy or strange-looking emails.
- Watch for random pop-up windows. These can look like advertisements or false antivirus software alerts. Be cautious of what you click and be skeptical of random pop-up windows containing enticing promises.
