New Proof of Concept virus for Macintosh OS X systems is released recently.
Malware description from anti-virus vendor Symantec is available here.

There is news coverage via Heise Security (sorry, in Deutsch) and SecuriTeam Blogs.

What the Symantec says is:

It infects other files when they are executed in the current directory, regardless of file name or extension.

The virus has an official name OSX.Macarena.

UserAgent: Mozilla/5.0 (Windows; U; Windows NT 5.0; fi; rv:1.8.0.7) Gecko/20060909 Firefox/1.5.0.7

Thanks for reporting.

I would point out that people should be careful with the words like "proof of concept", those words are more of less marketing words in my opinion.

[sdt=5342]Back in 2004[/sdt], a relatively unknown company called Intego issued a warning that they *discovered* the first "concept" Trojan on Mac OS X. Few weeks afterwards, most Mac users agree that it that company's tactic for its publicity.
