Computer Trojan Virus: Meaning

A computer Trojan refers to a program that appears to be harmless, but is in fact, malicious. It is a destructive program that acts as a benign application. You can confirm that a computer Trojan horse resides in your system if you come across strange activities and unexpected changes to your settings when the computer remains idle.

Key Types of Trojan Horse Viruses

  • Destructive Trojans: Proxy Trojan horse viruses use the victim’s computer as a proxy server. This Trojans allows the attacker to do anything on your computer, including credit card fraud and several other illegal activities. The attacker will also be able to use your system to launch malicious attacks against other networks.
  • FTP Trojans: FTP Trojan horse viruses open port 21 (the port for FTP transfer) and permits the attacker to connect to your computer using File Transfer Protocol (FTP).
  • Denial-of-Service Attack (DoS) Trojans: A DoS Trojan horse executes a type of attack that brings a network to its knees by flooding it with useless traffic. Several DoS attacks, such as the Teardrop and Ping of Death attacks, exploit limitations in the TCP/IP protocols. For all the popular DoS attacks, there are software fixes that system administrators can install to limit the damage brought about by the attacks.
  • Remote Access Trojans: A Remote Access Trojan (RAT) can provide the attacker with complete control of the victim’s system., this computer Trojan virus is usually hidden by attackers in games and several other small programs that unsuspecting users then execute on their PCs.
  • Security Software Disabler Trojans: This Trojan horse virus stops or kills computer security software such as firewalls or antivirus programs without the user’s knowledge. It is usually incorporated with another type of Trojan as a “payload.”
  • Data Sending Trojans: Data Sending Trojans supply the attacker with sensitive data, such as log files, passwords, e-mail address, credit card information or IM contact lists. These Trojans can look for pre-defined data, for example, only passwords or credit card information, or they can install a keylogger and send all recorded keystrokes back to the attacker.

How a Computer Trojan Virus Works

Below is an example of how a computer Trojan horse virus could be used for infecting a personal computer:

An official-looking email is received by the victim along with an attachment. This attachment contains a malicious code that gets executed immediately after the victim clicks on the attachment. Following this, the computer continues to work normally, hence the victim does not suspect that the attachment is in fact a computer Trojan that has infected his/her computing device.

The malicious code continues to be undetected until a specific date or until the time when the victim performs a particular action like visiting a banking website. When this takes place, the trigger activates the malicious code and the intended action finally gets executed. Based on how the computer Trojan virus has been developed, it may continue to be active, it may return to a dormant state or it may delete itself after it has successfully executed its intended function.

What is Forensic Analysis?

what is forensic analysis

Forensic analysis refers to a detailed investigation for detecting and documenting the course, reasons, culprits, and consequences of a security incident or violation of rules of the organization or state laws. Forensic analysis is often linked with evidence to the court, particularly in criminal matters. It involves the use of a wide range of technologies and investigative methods and procedures. Forensic specialists gather different types of information by working with electronic devices and also working in a conventional way with the information on paper.

Computer Forensics: Overview of Malware Forensics

Recently, malware forensics has become more significant with the cybercrime community causing destruction to technology, retail, and financial institutions. Cybercrime can bring danger to private and governmental organizations, and malware is a commonly used tool by cybercriminals for installing things such as worms, Trojans, and botnets to the infected device. The only way for organizations processing sensitive information to defend client and company data is to respond to malware with accuracy and speed.

Types of Computer Forensic Tools

  • Digital Forensics: Forensic techniques are used for retrieving evidence from computers. These techniques include identification of information, preservation, recovery, and investigation in line with digital forensic standards.
  • Mobile Device Forensics: Mobile device forensics refers to that branch of digital forensics that involves evidence found on mobile devices. These include personal digital assistants (PDAs), mobile phones, and tablets – basically, any computing device that has communication capabilities besides being portable. This branch of forensics suddenly gained popularity with smartphones, making it one of the most recent divisions of digital forensics.
  • Software Forensics: Software forensics determines whether software has been stolen. This is performed by analyzing and comparing a source code, and then detecting any possible correlation. Over the past few years, software forensics has been used in several high-profile intellectual property (IP) litigations.
  • Memory Forensics: When sophisticated attacks occur, data existing in the hard drive could either be permanently erased or no data is left on the hard drive, leaving almost no evidence for a forensic investigation. Memory forensics is the process of searching for possible artifacts in the computer’s memory (RAM).
