Some of the most high-profile ransomware cases in recent memory include the WannaCry and Petya outbreaks in 2017, which infected hundreds of thousands of Windows PCs around the world. However, ransomware such as EvilQuest target Mac computers specifically.

Cybersecurity experts stumbled into a ransomware variant late last month, but this one doesn’t target Windows devices. The malware, known as OSX/Filecoder.E, encrypts Mac data like any cryptolocker strain many businesses have seen in the past. However, unlike normal ransomware that release files after the Bitcoin ransom is paid, this new strain makes no such promises.
