New ransomware is targeting Windows and Linux PCs with a 'unique' attack

If Linux ever got even 10% of the desktop/laptop market, it would be effective to target it, and it would be extremely vulnerable.

I've had Linux servers hacked because I was a few days late at patching my WordPress....

oh! I thought Linux had some inherent / in-built architectural feature that made viruses impossible .

>It's an unusual form of ransomware because it's written in Java, deployed as a trojanised Java Runtime Environment and is compiled in a Java image file (Jimage) to hide the malicious intentions.

are there any options in browser settings / adblock extensions to block this thing ?

Can someone eli5 what this means for regular desktop users of linux distros?
