Free Security Tool for MS Office Files
Security company Sourcefire has released a freeware utility to help identify potentially unsecure Microsoft Office files. The tool, called OfficeCat, can be used to scan Word, PowerPoint, Excel and Publisher documents. Unlike other products that detect attempts to exploit known Microsoft vulnerabilities, Sourcefire said OfficeCat can determine if a file contains hostile content before it is opened.
