New malware exploits flaw in old versions of Office for Mac

. Microsoft researchers recently discovered a piece of Mac OS X malware that exploits a three-year-old flaw in old versions of Office for Mac. The threat uses a multi-stage attack, just like a Windows virus would. While Microsoft did fix the problem in 2009, the software giant notes that not every machine is up-to-date. The company's data indicates, however, that the malware is not widespread. “No operating system that exists outside a laboratory is entirely immune to malware,” Microsoft stated on its blog.
