Exploring Various Types of Trojan Malware
A Trojan horse, often called simply a Trojan, is a malicious software that disguises itself as legitimate but secretly takes over your device. Its purpose is to steal data, cause damage, disrupt operations, or compromise your network security.
Trojans imitate genuine applications to deceive users and systems. Users unknowingly download infected files, and once installed, the Trojan performs its malicious functions.
Though often mistaken for viruses, Trojans differ. Viruses can replicate themselves, whereas Trojans cannot, but both can inflict serious harm.
How Do Trojans Operate?
Named after the legendary Trojan Horse, these malware are designed to deceive. Just as the Greeks hidden inside the wooden horse infiltrated Troy, Trojans appear as harmless files or programs to infiltrate your device. They often arrive via infected email attachments or fake app downloads, then activate to damage or access your system.
Sometimes, seemingly legitimate emails or downloads are actually compromised. When executed, these files release malware that spreads and corrupts files across your device.
Below are some common Trojan types:
- Backdoor Trojan
Creates hidden access points, allowing hackers to control your device or steal data. - DDoS Trojan
