What is "Trojan Horse"?

Introduction


With the rapid advancement of technology, cybersecurity threats have emerged as a major concern in the digital world. The ever-growing sophistication of malware, viruses, and other forms of malicious software has made it increasingly difficult to ensure the security of computer systems and data. One of the most insidious types of malware in malware is the Trojan Horse. In this article, we will thoroughly examine what Trojan Horse is, its history and development, its types, how it works, ways to prevent it, commonly used antivirus software against it, and finally the takeaway.

What is a Trojan Horse?


A Trojan Horse, simply known as Trojan, Alternatively referred to as Trojan malware, is a malicious software that is designed to infiltrate computer systems with the intent of stealing data or damaging the system. When a Trojan Horse infects a computer, it creates a backdoor for cybercriminals to enter the system and carry out their harmful activities surreptitiously.

Trojan Horses are often distributed through disguised and deceitful methods; hence, they are rarely identified until they've caused substantial damage. It derives its name from the Greek myth where a fake wooden horse penetrated and conquered the city of Troy in ancient Greece only to unleash an army of Greek soldiers hidden inside upon arrival. In malware formations, it remains the same.

The History and Development of Trojan Horses


The Trojan Horse takes its name from the ancient Greek story of the Trojan War. The Greeks were unable to conquer the city of Troy, so they constructed a horse as a cunning trick to be offered as a gift to Troy's citizens. Unknown to Troy, there were Greek soldiers hidden inside the horse that infiltrated the City, opened the gates, and conquered Troy.

In the late 1900s, the earliest versions of Trojans were developed as practical joke programs or programs used to teach members of the computer community about ethical hacking, but several people misused the programs as hacking tools; hence labeled an illegal practice.

As the Internet's appeal further sank into businesses and households worldwide, Trojans saw more use in email and instant messaging channels. The hacker groups charged more professional coders to boost the Trojan's performance periodically.

Types of Trojan Horse


There are different subclasses of Trojans, but they are primarily grouped according to their purpose for ease of identification. Here are some of the most prevalent Trojan Horses.

Security Software Disabler

A Security Software Disabler Trojan stands distinctly to disable pre-installed software meant to prevent large viruses. Typically, once the Trojan Horse has hacked a user's computer system, security programs intended to prevent malicious codes on the computer become deactivated.

Ransomware Trojan

This Trojan Horse is tailored to steal customers’ information and hijacked web pages demanding a particular ransom worth giving back the livelihood. Ransomware can display unlock codes that pay their wallets to make a profit operating with uninterrupted work for a stolen license.

Spy Trojan

Spy Trojans are exclusively accessed by Remote Access Trojan campaigns with a predator’s malicious intent to hijack control and spy by webcam, microphone, system logs, browser data, action keys, and bring back sensitive photos, videos, and intellectual data. Remote Access Tool Trojans don’t seem to have holes besides rigged software packages and social protocol scenarios covered by natural communication.

Data Intercept Trojan

Data Intercept is the primary carrier of most skilled hacking groups that exhaust interception code in their exploits primarily. In espionage programs fueling malicious political and financial force structures, the Data Interception Trojan resonates for the credit and calling cards thieved and payroll account chart depletion exploited.

How Does a Trojan Horse Work?


Trojan Horses have been considered a useful strategy used by cybercriminals to gain complete control over the physical and digital plan via a digital portal. They deceive and conceal all details of their identity, including the software contents created. Likely, they are inherently manipulated according to the purveyors' requests given rise to multiple Trojan hosts.

Remote Access Trojan(s) or ‘RAT’ combines malware execution software injected on pre-infected or standard websites and thereafter pack and run onto computer processes seeking repeated registration in allowed domains without the owners reminding overs multiple sign-ons eventually notations. Without consent installed by clicking on email attachments delivering a digital download headed by some type of disguising or script that promises benefits or concerns information setup.

Generally, in Trojan deployment, the suspects track ad landing activity and send presentable display screens hosted on far away influencers demanding or routing funds on sudden basis stolen account numbers balance balances, selling information to young people under demographic target this system says as scammers with potentially worse offer than many.
