Malware Glossary
When you read about computer security and malware, the terminology can get dizzy. You may feel that you have entered a world with some very strange words that you can only guess. To help you understand malware, here is a look at the most common words that describe malicious software that can harm your computer and mobile device, and endanger your security and privacy .
A comprehensive look at malware terminology, including viruses, worms, spyware, and all other threats that endanger your Mac and your data.
Malware Glossary
Malware is the blanket term for all malicious software. This is a convenient term, as I can use it for any of the categories below. Sometimes, a specific piece of malware may be composed of more than one of these categories, so the term blanket is economical to use, and makes things easier to understand. In addition, some of these terms describe the way malware is distributed, others the way they propagate, and others the types of tasks they perform. Users do not always need to know which type of malware has infected their device. Since some words named malware describe how software is installed, it can be useful to understand how users can protect themselves. (See phishing, Trojan horse etc.)
What is a computer virus?
Definition of virus
A virus on a computer is a specific type of malware that self-replicates, such as infectious agents designated in humans and animals alike. Like living viruses, computer viruses attach themselves to hosts for moving around and breeding. The term virus refers to the means of replication, not the way malware works on a computer. Viruses circulating on floppy disks and CD-ROMs; They now roam the Internet, hide inside files and applications, or spread through infected USB sticks. The term virus is often used as a blanket term, while the term malware is usually more appropriate. And, because historical viruses were the first type of malware that attacked personal computers, the security industry often uses the term “anti-virus” for software that detects and eradicates malware.
Example: A proof of concept virus, identified as multi / clapzok. Targeted Windows, Linux and OS X 32-bit executables.
What is a worm?
Definition of worm
On a computer, a worm is similar to a virus, in which it repeats itself. But unlike viruses, worms do not need to attach to other files. They often repeat over the network, providing a particularly dangerous rendering.
Example: On February 16, 2006, the “Oompa-Loompa” worm was discovered by Intego, identified as OSX / Oomp.A, targeting Mac OS X users via iChat Instant Messenger.
What is Trojan horse?
Trojan horse definition;
Trojan horse, or simply Trojan, is a type of malware disguised as a useful piece of software or data file. It can actually take action on computers that are legitimate or appear, but will install malware or perform malicious actions. A Trojan horse can also be legitimate software that has been altered to install malware. The name comes from the wooden horse that the Greeks built to attack the city of Troy. Apparently, the people of that city did not know that they should not open unwanted attachments.
Example: The Ventir Trojan, identified by Intego VirusBriar as OSX / Ventir, used a dropper program (such as the Trojan horse) to infect the Mac.
What is ransomware?
Ransomware definition
Ransomware is a type of malware that shuts down a computer or hides a user’s files until a ransom is paid. It can be installed by a Trojan horse, or downloaded by visiting a malicious website. Ransomware is big business, in which cyber-criminals make a lot of money from users who need to access their files. These people often have sophisticated fulfillment setups with call centers and customer support to complete payments. The best prevention against ransomware, apart from using anti-malware software, is to regularly back up your files, so you always have a copy of them available.
Example: KeRanger, identified by InteX VirusBarrier as OSX / KeRanger, was the first major macOS ransomware.
What is botnet?
Botnet definition;
A botnet is a network of computers whose access is compromised, and which is controlled remotely. These personal computers are often called bots or zombies
