The Most Significant Type of Malware

The Most Significant Type of Malware – Cybercriminals design malware to attack computer functions, steal data, bypass access controls, and cause damage to the host computer, its applications or data. Before we fight against malware it’s good we know the most significant and common types of malware that are used to attack an agency:
Adware is the name of the malware given to programs designed to display advertisements on your computer, direct your search requests to advertising websites and collect marketing data about you. Examples are annoying advertisements such as the appearance of pop-ups on the desktop or ads that appear by displaying specialized search engines.
Spyware is a software or software that has the duty to spy on the activities of internet users, almost the same as spy (spy) in general. Basically Spyware is not a group of viruses because it has positive uses, but there are perpetrators who abuse it to steal information from internet users.
Characteristics of this virus are usually done by attacking and infecting files that are on the target system. Although their threats have diminished in recent years, the virus has been the cause of widespread destruction over the years. In addition to stealing and corrupting data, they use system resources and often make the host system ineffective or even useless.
Almost like a virus, worms are contagious and cyber criminals design to replicate themselves. However, the worm replicates without targeting and infecting certain files that are already on the computer. Worms carry themselves in their own container and often limit their activities to what they can achieve in applications that move them. They use computer networks to spread, rely on security failures on target computers to access them, and steal and delete data.
The Trojan
Trojan is a software that can damage or delete files that are on the system. The purpose of the Trojan is to obtain information from the target (passwords, user habits recorded in the system log, data, etc.) and control the target (obtain user access rights). Various well-known Trojans include Remote Access Trojans, Data Sending Trojans, Destructive Trojans and others.
This program is used to record every keystroke entry made by a computer, often without the user’s permission or knowledge. Keylogger has legitimate uses as a professional IT monitoring tool. However, keystroke logging is usually used for criminal purposes, capturing sensitive information such as usernames, passwords, answers to security questions, and financial information.
Rootkit is malicious software that gives unauthorized users privileged access to a computer. After the rootkit is installed, the rootkit controller has the ability to execute files remotely and change the system configuration on the host machine. Rootkits cannot be reproduced or replicated by themselves. They must be installed on the device. Because where they operate (in the lower layers of the operating system application layer, the operating system kernel, or in the basic input / output system (BIOS) with special access permissions), they are very difficult to detect and even more difficult to remove.
Bots and Botnets
Like robots, bots are malicious programs designed to infiltrate computers and automatically respond to and execute instructions received from central commands and control servers. Bots can replicate themselves (like worms) or replicate through user actions (such as viruses and Trojans). The entire network of compromised devices is known as a botnet. One of the most common uses of botnets is to launch a distributed denial of service (DDoS) attack in an effort to make a machine or the entire domain down.
Very famous in 2017 is the wannacry which had shocked the world with the arrival of the latest variant of this ransomware. Because this type of malware that locks the data on the victim’s computer uses encryption. The cyber criminal behind this malware demands a ransom payment before decrypting data and restoring access to victims.
Internet users need to increase their awareness of malware attacks before they have a serious impact. These malware attacks are not only harmful to the users themselves, but can also have an impact on the surrounding environment, family and also the company where they work.
Every company or organization does not allow to be able to monitor the activities or activities of their workers at any time in using the internet, which has the potential for theft of important company data.
