Graybird 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.
Trojans, within the context of computer security, utilize strategies to deceive users into unintentionally installing or executing them on their systems. They often masquerade as genuine files or programs, leading users to believe they are legitimate. Once a Trojan is installed, it can carry out various harmful actions without the user’s knowledge or consent. These actions may involve gaining unauthorized access to the system, stealing sensitive data, or introducing additional malware.
Trojans are known for their ability to carry out various malicious activities, making them a significant threat in the realm of computer security. One of their primary objectives is to steal personal information, including sensitive data like login credentials and credit card details. By operating discreetly within the infected system, Trojans can silently gather this information and transmit it to malicious actors for exploitation.
Trojans employ a wide array of distribution methods to infiltrate systems and deceive users. These methods include email attachments, malicious downloads, compromised websites, and even disguising themselves as legitimate software downloads. By utilizing these tactics, Trojans aim to lure unsuspecting users into unwittingly installing or executing them.
