Understanding Trojan Malware

Trojan malware is a type of malicious software that disguises itself as legitimate software. Cybercriminals and hackers use Trojans to gain unauthorized access to systems. They employ social engineering tactics to deceive users into loading and executing Trojan files. Once activated, Trojans enable cybercriminals to spy on users, steal sensitive data, gain backdoor access to systems, and manipulate files.

The term “Trojan” comes from the ancient Greek tale of the Trojan horse, which led to the downfall of the city of Troy. Although your computer is not a city, it can still be compromised by Trojans. Similar to the deceptive horse, Trojans hide within harmless programs or try to deceive users into downloading them. The name “Trojan” was first used in a 1974 US Air Force report that speculated about the potential compromise of computers.

Many people refer to a “Trojan” as a Trojan virus or a Trojan horse virus, but these terms can be misleading. Trojans themselves cannot self-replicate, but they spread by pretending to be useful software or content while containing hidden malicious instructions.

For a Trojan to work, it needs to be executed by the victim. There are several ways in which a device can become infected. For example, if a user falls victim to a phishing or social engineering attack and opens an infected email, the Trojan can be activated. Attackers can also exploit software vulnerabilities or gain unauthorized access to install Trojans. Additionally, hackers may create fake Wi-Fi hotspots that imitate legitimate networks, redirecting users to fraudulent websites that contain browser exploits capable of predicting any downloaded file.
