Trojan Horse

Quick Answer

A Trojan Horse is a type of malicious software that disguises itself as a legitimate program. It tricks users into downloading and running it, allowing attackers to gain unauthorized access to their systems.

Overview

A Trojan Horse is a deceptive software that appears harmless but carries harmful code. It often masquerades as a useful application, like a game or a utility, to entice users into installing it. Once installed, it can create backdoors for cybercriminals to access sensitive information or control the infected device remotely. The way a Trojan Horse works is quite simple yet effective. Users unknowingly download it, thinking they are getting a legitimate program. After installation, it can execute various harmful actions such as stealing personal data, logging keystrokes, or even encrypting files for ransom. Understanding Trojan Horses is crucial in the realm of cybersecurity. For example, a well-known incident involved a Trojan that pretended to be an antivirus program, tricking users into paying for fake services. This highlights the importance of being cautious when downloading software and keeping security systems updated.
