How Criminals Use Malware and Ransomware to Attack Computers?

Malware comes in many forms and is used to attack computers. Most infections are spread through email and websites. They usually require permission for installation and will look like an official request from a trusted brand. Another method criminals utilize as common examples of malware is exploiting a computer’s missing security update. 

Ransomware

Ransomware is a computer virus used by criminals to extort money from victims. It was first created in 1996 by Adam Young and Moti Yung. They used crypto virology to create an attack that prompted the victim to send asymmetric ciphertext to the attacker in exchange for a decryption key. The attacker then launders the money using traditional money laundering techniques and digital currency-specific venues.

Fortunately, there are ways to protect yourself from ransomware attacks. One of the most effective measures is to ensure that your security software is updated. Regular updates to software include patches that fix security flaws. These updates can also protect your computer from ransomware attacks.

Adware

Malware is programs that have been designed to cause harm to computers. These programs can be used to spy on you, steal data, or make money. Some of these programs are more dangerous than others. If you’re concerned about the possibility of infection with malware, consider using a trusted malware removal tool to prevent the infection of your computer.

Malware is designed to get into your computer and execute when your system is vulnerable. For example, it might be executed during boot-up or periods of high-traffic activity. They also have the potential to infect other systems.

Remote access Trojans (RATs)

Remote Access Trojan (RAT) is a malware program that grants the complete hacker control of the victim’s computer. It is generally downloaded via the internet or through malicious emails and installed on the target computer without the victim’s knowledge. Once installed, a RAT can monitor the user’s behavior, access sensitive information, activate the webcam, and even change files on the computer.

RATs became more popular among cybercriminals and state-sponsored attackers as they gained more features. 

Cryptojacking

Cryptojacking is a growing business, and criminals increasingly use advanced techniques to increase profits. Some of these methods are described below. To counter these threats, users should always protect their devices and stay on top of evolving malware and phishing methods. These techniques can be difficult to detect, but there are ways to keep them at bay.

Cryptojacking malware load on a device and use its computing power to mine cryptocurrency. This is done by hijacking the compromised device’s memory, battery life, and processing power. 

Cyberextortion

Cyberextortion has become a major concern for organizations as more sensitive data is stored online. Many of the world’s largest organizations have fallen victim to cybercrime gangs. Cyber extortionists profit from the value of information and the fear of being exposed. They often threaten to release data if they do not get paid or provide sensitive information.

Companies are advised to implement cybersecurity measures to limit the number of cyber extortion incidents. These include risk analysis, risk management programs, audit logs, and participation in information-sharing organizations.
