Be Careful When Opening Office Files

Here’s some advice you’ve probably heard before: Don’t open files if you don’t know where they came from. And even if you know the person who sent it, it’s wise to ask if they meant to send it if you weren’t expecting to receive a file from them. The reason this is newly relevant is because Russian hackers have been using a vulnerability in Microsoft Office to install malware on the computers of unsuspecting people. You can get it just by opening an infected Office file.

From Wired:

And while the targets McAfee has detected so far are in Germany and France, the hackers have been fooling victims into clicking with file names that reference US-focused topics: both a US Army exercise in Eastern Europe known as SabreGuardian and last week’s ISIS truck attack that killed eight people on a Manhattan bike path.
