WannaCry is a virulent form of ransomware that infected outdated, insecure versions of Windows at catastrophic scale. Attacked system were encrypted and users shut out of their files, the only thing left accessible — a demand for $300 in Bitcoin to unlock the systems.
Richard Devine, writing for Windows Central:
Does that mean Mac users don't have to worry?
If you're running macOS on Mac hardware, you don't have worry about WannaCry specifically, at least so far.
If you're running an outdated version of Windows on Mac hardware, especially Windows XP, then it's just as vulnerable as any similar Windows system.
Other forms of ransomware have been discovered on the Mac in the past, though, so it's something everyone should be vigilant about.
How do you protect yourself from ransomware?
There are a couple of things everyone should do to minimize the chances of being adversely affected by a ransomware attack:
- Always have an up-to-date backup. That includes local backups like TimeMachine and online backups from a service provider like BackBlaze, Crash Plan or Carbonite.

- Don't click on links in emails or on web pages you aren't 100% sure about. If something looks fake, avoid it, ask about it, or type the site name into your browser and navigate from there.
Wait, these exploits leaked from the NSA?
But... but, last year didn't the government wanted Apple to create a backdoor in iOS they claimed would never leak?!
It would be funny if it wasn't so terrifying.
