What is a Trojan?


A Trojan, also known as a Trojan horse, is a type of malicious software or program that appears to be legitimate or harmless but actually contains malicious code. It derives its name from the ancient Greek story of the Trojan War, where the Greeks used a large wooden horse to deceive the Trojans and gain entry into the city of Troy.
In the field of computer security, a Trojan is a type of malware that deceives users by disguising itself as a legitimate file or program. Its primary objective is to trick users into willingly installing or executing it on their systems. Once the Trojan is successfully installed, it can carry out a wide range of malicious activities without the user’s knowledge or consent.
Trojans are notorious for their ability to carry out various malicious actions that can have detrimental consequences. Once they infiltrate a system, they can stealthily steal personal information, including login credentials and credit card details, jeopardizing individuals’ privacy and security. Additionally, Trojans have the capability to install additional malware, further compromising the integrity of the infected system. They can also grant unauthorized access to the compromised system, potentially leading to unauthorized activities or even complete control by malicious actors.
Trojans employ diverse distribution methods, making them a persistent threat in the realm of cybersecurity. They can be disseminated through email attachments, malicious downloads, compromised websites, or even camouflaged as legitimate software downloads. By leveraging these deceptive tactics, Trojans exploit vulnerabilities present in the operating system or applications to gain unauthorized access to the targeted system. Once inside, they execute their malicious activities, compromising the system’s security and potentially causing significant harm.
