Microsoft Announces Vulnerability in Office that affects nearly all versions of Windows

On Tuesday, Microsoft warned Windows users that cyber criminals are exploiting a recently discovered vulnerability in Microsoft Office. Users are sent an attachment that will open a Power Point or Office document (.pptx, .pptm, .ppt, .docx, .xls). The document opened will run other programs in the background, allowing the hacker gain access to everything on the computer. Users with administrator rights pose the greatest risk if infected.

What is being done about it?

Microsoft released a fix for this yesterday. You should check with your IT Administrator to ensure your systems are updated with the latest Microsoft Security updates and patches.

How can I protect myself?

Any unexpected emails with attachments to Power Point, Word or Excel documents should be treated with concern. If you receive any emails that appear suspicious, always check with your IT Administrator before opening an attachment or a link. The time spent to do so could very well save a day or more of down-time.
