Defining the Most Common Types of Malware

Malware is a term that stands for ‘malicious software,’ and are created by hackers in order to get access to things they normally should not be able to. There are thousands of different malware programs floating around the internet, waiting for someone to mistakenly download it to wreak havoc on your computers. With so many different types of malware, it can get a little difficult to recognize malicious programs before it’s too late. Here are a few of the most popular types of malware you’ll want to look out for, and how they work to steal your valuable assets.

Adware

Adware, short for advertising-supported software, is a special type of malware that is meant to deliver advertisements where they normally wouldn’t appear. These types of malware are often attached to ‘free’ software or applications, and are most often used as a way to generate revenue.

Bot

These programs are created to automatically a specific operation automatically, such as collecting information. Hackers can install bots onto a network or personal device for DDoS attacks, use them as a form of adware, hide them in sites to collect data, or even distribute other types of malware when downloaded.

Spyware

This kind of program is able to track anything a user does on their device, including anything they enter into their computer. This can include things such a passwords, personal information, or even credit card numbers. In addition, many spyware programs have other uses, such as the ability to modify security setting or interrupting internet connections.

Ransomware

Ransomware is a type of malware that will lock a user out of their device or network until a transaction is completed. This is done either by encrypting the data stored on the device, or by shutting the system down entirely. Typically, these programs will ask a user to send hundreds of dollars in order to get their data back.

Rootkit

A rootkit is designed to remotely access a device or network without being detected by either the user or any security programs. These programs often activate during a time when the device is not being used, making it one of the hardest forms of malware to detect. Once inside, a rootkit can access files, change settings, steal information, or even hide other types of malware.

Trojan

One of the most well-known forms of malware, a Trojan malware disguise itself as a normal, safe file or program to try and trick users into downloading it. Once downloaded, the Trojan gives access to the affected user, allowing them to steal data, monitor activity, or install more malware.

Virus

Much like viruses in the human body, a computer virus is able to copy itself to other computers or systems, infecting them as they continue to spread. Typically, viruses attach to a program and will activate when the infected program is launched. However, they can also be spread by documents, script files, or any other file that is shared.

Worm

Worms are similar to a virus in that they can create copies of themselves to spread from device to device, infecting every one as it goes along. The major difference is that while a virus needs to be spread via a human or host program, a worm is able to self-replicate itself and spread on its own.
