Malware is the abbreviation of the English combination of "Malware" Malicious Software. Malware is called all of the worms, trojans, and other malicious computer programs that hackers use to access sensitive information on users 'or organizations' systems. Malware, as defined by Microsoft, is a complete definition of software designed to damage a single computer, server, or computer network.
Malware types
There are several different ways to categorize malware; The first is about how malware replicates.
You've probably heard of the terms virus, trojan, and worm.
Worm is part of independent malware that can spread from computer to computer.
A virus is another type of malware that hijacks the code of another independent program.
Although Trojan is a software that does not have the ability to reproduce itself, it shows itself as a useful software for the user and manipulates the user to activate it. So it starts to spread to the whole system.
Another way to categorize malware is related to what it does after successfully infecting the victim's system. There are a variety of potential attack techniques commonly used by malware.
Spyware; Webroot is defined as software designed to secretly collect data about a user by definition of Cybersecurity. It is basically designed to capture data that you send and receive while using your computer and forward it to a third party. For example, a keylogger is a great example of spyware that is used to capture passwords by recording all keystrokes that the user makes with his keyboard.
Rootkit (root user team); It is a set of software tools that provide remote access and control to a computer or a system by definition of TechTarget. The root user team, which successfully reaches the target system, takes over the administrator permission and can use this power successfully.
Adware; A type of malicious software that forces your internet browser to download more malware and redirects it to such web ads.
Ransomware (ransomware); It is malicious software that encrypts your hard drives after infiltrating your system and requests payments like Bicoin in exchange for these passwords. It is mathematically impossible for victims to access files encrypted by this software.
Cryptojacking; Malware that forces hackers to become victims of unnoticed or forced bitcoin mining. This malware uses your entire CPU setup to run Bitcoin mining by running as a javascript in the background of your system.
Malicious advertising (Malvertising); software used to infiltrate victims' computers, without the knowledge of the user of legitimate advertisements or ad networks. For example, a cyber pirate pays to advertise on an ordinary website and advertises on this site. Then, when a user clicks on the ad, the coding in the ad redirects it to a malicious website or installs malicious software on their system. This system can be installed on the computer automatically upon the user's request.
Some malware can be part of many categories. For example, although WannaCry appears as a ransom software, it can be used to perform many different attacks. Similarly, Emotet was found to be used both as a trojan and a worm.
Most malware infects systems via email and phishing mail. The best way to prevent this is to strictly protect your emails and ensure that your users are sure how to detect the danger. Also make sure that it is safe before running attachments, even in emails from someone you know to your system.
Apart from that, using your entire system with the necessary precautions in the latest version will keep many malware away from your system. When you want to focus on the files you want to protect, never forget to back up these files frequently, especially in order to be protected from ransomware. So even if your hard drive is encrypted, you can easily fend off this threat.
