What is SpyEye Trojan?

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 realm of computer security, Trojans are deceptive malware that lure users into unwittingly installing or executing them on their systems. They often masquerade as legitimate files or programs to deceive users. Once inside a system, Trojans can carry out a range of malicious activities without the user’s awareness or consent.
Trojans are notorious for their versatility in carrying out malicious activities. When they infect a system, they can stealthily steal sensitive personal information, such as login credentials and credit card details, putting individuals’ privacy and security at risk. Furthermore, Trojans have the ability to install additional malware, which can lead to further compromises and vulnerabilities within the infected system.
Trojans employ a range of distribution methods to infiltrate systems and pose a constant threat to cybersecurity. They can be disseminated through email attachments, malicious downloads, compromised websites, or even disguised as legitimate software. Once they find a way into a system, Trojans exploit vulnerabilities in the operating system or applications to gain unauthorized access and execute their malicious activities.
