One kind of malware that sneaks onto a computer under the guise of a trustworthy application is called a Trojan Horse virus. Typically, the delivery method involves an attacker hiding malicious code within legitimate software through social engineering in an attempt to obtain users’ system access through the software.
Answering the question "what is Trojan" simply means that it’s a kind of malware that usually infects a user’s device after disguising itself as a free download or an attachment in an email. Once downloaded, the malicious code will carry out the intended task of the attacker, which could be stealing confidential information, gaining backdoor access to corporate systems, or spying on users’ online activities.
A Trojan may be operating on a device if it exhibits odd behavior, such as sudden changes to the computer’s settings. Emails with attachments that appear authentic and are spammed to as many recipients as possible are the means by which a Trojan virus spreads. Cybercriminals can also use social engineering techniques to trick users into downloading a malicious application, which can infect a device with a Trojan. Trojan malware can also propagate to other computers through a compromised computer.
Cybercriminals employ a variety of Trojan horse virus types to execute a range of operations and attack techniques. Trojans that are most frequently used are:
- BANKER
- BACKDOOR
- EXPLOIT
- FAKE ANTIVIRUS
- GAME-THIEF
- DOWNLOADER
- INFOSTEALER
- MAILFINDER
- RANSOM
- REMOTE ACCESS
The most common types of Trojans that are used are:
- SUNBURST
- ROOTKIT
- SHORT MESSAGE SERVICE (SMS)
- SPY
It is common for a Trojan horse virus to linger on a device for months without the user being aware that their computer has been compromised. Using a Trojan scanner or malware-removal program to search a device is the best way to identify a Trojan. Trojan attacks have been known to infect computers and steal user data, which has resulted in significant damage. A few well-known Trojan instances are ZEUS OR ZBOT, TINY BANKER, and RAKHNI TROJAN. The FortiGuard Labs Global Threat Intelligence system is utilized by the Fortinet antivirus services.
Let’s examine the spread of Trojan horse malware.
- Trojan horses are dishonest programs that mimic one function while actually carrying out a malicious one.
- Trojan horses have the ability to function as independent tools for attackers or as a base for additional malevolent actions.
- Trojans can infect computers through malicious websites, phishing emails, social engineering, infected attachments, and unapproved downloads.
- Trojans have the ability to download and execute additional malicious code, create covert communication tunnels, track user behavior, obtain root-level access, and transform targets into zombies for denial-of-service attacks.
- Examples of Trojan horse malware are Cryptolocker, ILOVEYOU, Zeus, and Stuxnet.
- Organizations can use web application firewalls, endpoint protection platforms, threat hunting, and user complaint triage to detect and prevent trojans.
- User rights management, web application firewalls, data masking and encryption, data loss prevention, user behavior analytics, data discovery and classification, database activity monitoring, and alert prioritization are just a few of the data protection solutions that Imperva provides that can aid in the detection and prevention of trojans.
Let’s discuss whether or not a Trojan horse is good.
- One of the most prevalent and harmful threat types that can infect your computer or mobile device is a Trojan horse, also known as a Trojan.
- Trojans, as their name suggests, are malicious programs that are intended to cause harm that are typically downloaded from the Internet under the guise of benign or helpful software.
- Trojans come in many different forms, and a lot of them are capable of launching extremely intelligent and complex attacks.
- Trojans are extremely dangerous because they can be used for one or more destructive purposes.
- Trojans are not self-replicating like viruses are; instead, they are only disseminated by users who unintentionally download them, usually from an email attachment or by visiting a compromised website.
- You can take the following actions to prevent downloading a Trojan horse:
- Keep in mind that because they are so successful, Trojans are common.
