torjan

torjan refers to a type of malicious software, commonly known as a Trojan horse. It is named after the ancient Greek stratagem of the Trojan Horse, where a wooden horse was used to infiltrate the city of Troy. In computing, a Trojan is a program that disguises itself as legitimate software or a useful application. However, once installed on a user's system, it performs harmful actions without the user's knowledge or consent.

These harmful actions can vary widely. Some Trojans may steal sensitive information such as login credentials, financial data, or personal files. Others might create backdoors, allowing remote attackers to gain unauthorized access to the infected computer. Some Trojans are designed to download and install other malware, such as viruses, worms, or ransomware, further compromising the system's security. They can also disrupt normal computer operations, delete files, or use the infected machine as part of a botnet for launching further attacks.

Trojans typically spread through deceptive means. Users might be tricked into downloading them from untrustworthy websites, opening malicious email attachments, or clicking on infected links. They often exploit social engineering tactics to persuade users to execute the malicious program. Unlike viruses or worms, Trojans do not usually self-replicate. Their primary goal is to deliver a payload of malicious functionality. Protection against Trojans involves using reputable antivirus software, keeping systems updated, exercising caution when downloading files or clicking links, and being generally aware of cybersecurity best practices.
