A Trojan may seem like an authentic file or app, but it isn’t. The aim of a Trojan is to fool you into loading up and executing malicious software onto your computer. After it’s been successfully installed, the Trojan can then execute a wide range of harmful actions, depending on its design.

Trojans are sometimes referred to as Trojan viruses, but this isn’t a correct term. Viruses, by definition, can replicate themselves after execution, and a Trojan is unable to manage this. A Trojan must always rely on a user action, but despite this, many people still refer to Trojan malware as Trojan viruses.

The malware, named for the Greek legend that appeared to be a gift and resulted in the fall of Troy, is essentially a malicious piece of software or code that will take control of your device. After it assumes power, it can steal data, damage data, or inflict other harm to your network, systems, and the data they contain.

How exactly do Trojans function?

A typical Trojan scenario begins with a user receiving an email. It appears to be legitimate, sent from a trusted colleague, client, or supplier, and it includes an important attachment that it requests the recipient has a closer look at. They click on the link, download the attachment and open the file, but, inadvertently, they have installed malicious software on their computer. By executing the program, the user has enabled the malware to spread to multiple files and cause harm to their device.

Different forms of Trojan to remember

Trojans are typically named for the tactic they are employed for. Below are just some of the known Trojans classified by cybersecurity professionals.

Exploits are a type of Trojan that contain malicious code engineered to use a known weakness in an application running on a computer, while Rootkits are Trojans that hide harmful activity or bugs on a network, helping other malicious software to remain undiscovered.

Often used against e-commerce sites and online banking systems, Trojan-Bankers are programs designed to steal payment card details or bank account data.

Finally, Backdoor Trojans offer threat actors remote authority over compromised devices. With this level of control, the hacker can execute any action they select, deleting, sending or receiving confidential data, or simply viewing it.
