macOS malware includes viruses, trojan horses, worms and other types of malware that affect macOS, Apple's current operating system for Macintosh computers. macOS (previously Mac OS X and OS X) rarely suffers malware or virus attacks,[1] and has been considered less vulnerable than Windows.[2] There is a frequent release of system software updates to resolve vulnerabilities. Utilities are also available to find and remove malware.[1]
History[edit]
Early examples of macOS malware include Leap (discovered in 2006, also known as Oompa-Loompa) and RSPlug (discovered in 2007).
An application called MacSweeper (2009) misled users about malware threats in order to take their credit card details.
The trojan MacDefender (2011) used a similar tactic, combined with displaying popups.
In 2012, a worm known as Flashback appeared. Initially, it infected computers through fake Adobe Flash Player install prompts, but it later exploited a vulnerability in Java to install itself without user intervention. The malware forced Oracle and Apple to release bug fixes for Java to remove the vulnerability.

- Lamadai – Java vulnerability[3]

A trojan known as Keydnap first appeared in 2016, which placed a backdoor on victims' computers.

Adware is also a problem on the Mac, with software like Genieo, which was released in 2009, inserting ads into webpages and changing users' homepage and search engine.
Malware has also been spread on Macs through Microsoft Word macros.
Ransomware[edit]
In March 2016 Apple shut down the first ransomware attack targeted against Mac users, encrypting the user's confidential information.[4] It was known as KeRanger. After completing the encryption process, KeRanger demanded that victims pay one bitcoin (about US$400 at the time, about US$9,150 as of July 1, 2020) for the user to recover their credentials.[5]

This “anti-virus” software is malware (i.e. malicious software). Its ultimate goal is to get the user's credit card information which may be used for fraudulent purposes.
