There’s never been an instance of widespread malware built with a dedicated ability to persist on a Linux host through Wine.

It wouldn’t be hard at all for a hacker to manually wire up linux-specific malware on a computer once they had a RAT running in Wine, but there’s no credible risk of windows malware automatically installing “linux viruses” at present.

Sadly newsforge (the site linked in the above article) no longer hosts said article. Sounded like a fun read!
