A linkbait title. From the article itself:

"However, this malware does not use any particular function unique to Windows 8 and we know that this malware existed before the launch of Windows 8."

Yep, better title on Slashdot: http://tech.slashdot.org/story/12/11/18/0619247/new-malware-...

Has the title changed since submission? It makes no mention of Windows 8 now (current title is "Malware Uses Google Docs as a Proxy Server").
