For starters, I just want to clarify that this isn’t a shot at OP, more so this is a criticism of the linked article.
So the article can be summarized as such:
Ransomware is a problem
There are Linux versions now.
Some comments about Linux being on 3% of the desktops now. Not sure what the point of this was… since the author then says that Windows is still 80%?
Linux servers are a much bigger/viable target, because the Internet runs on Linux, including financial sector, databases, “always on” systems, etc etc…
Ends the article with generic best practices like “deploy modern EDR” and “proper backups”.
All in all, this article contributes very little in terms of informing the reader or making any sort of original or insightful claim.
