On Wednesday, the world learned about a bug in the popular Unix, Linux, and Mac OS X command line interpreter Bash.
Discovered by engineers at Red Hat, this bug is known as Shellshock, and allows an attacker to run commands in the Bash shell. Since the bug was announced, Bash has been updated for the major platforms it affects—so it’s pretty easy to update and protect systems.
But there’s a problem: Bash is so widespread, and installed on so many devices—such as cable modems, routers, and other devices with embedded Linux operating systems—that it will be difficult, if not impossible, to fully patch everything that’s affected. (Windows users are generally unaffected by Shellshock, unless they’ve specifically installed Bash along with Cygwin, Git Bash, or other third-party packages.)
And that’s what makes it so important to update and protect what you’re able to fix.

If you have kids, then your computer, phone, or tablet may be chock full of protective measures, as it should be. You’ve also most likely talked to your children about browser safety– where they are allowed to go online, what they are allowed to post, and whom they should tell if they come across something inappropriate.
However, it’s not uncommon for a child to go to a friend’s house or a public kiosk computer that lacks those protective measures you’ve put in place at home.
Here are four browser safety tips to help your kids navigate some hazards of the Internet—and suggestions for turning those tips into teachable moments.

Here on Monday Productivity Pointers, I love to talk about cloud apps. I love using apps that you can access from anywhere—your computer, laptop, phone, or tablet. This week, we’ll discuss an important topic around cloud apps: how to secure yourself when using them. In my first video, I’ll show you how to enable two-step authentication, a more secure way of logging in, also referred to as “two-factor authentication.”
More and more cloud apps are offering two-step authentication. When you enable it, step one is to log in to the app with your user name and password as usual. You’ll then receive a text message on your phone from the cloud app itself, containing a second password. Step two is to go back into the app and enter that second password for access.

Your business may involve creating and sending contracts to your clients—but the problem with using Microsoft Word documents for contracts is that they can be easily altered. It’s important to know when you receive a contract back from your clients that it’s the exact same contract you sent them.
In this week’s Monday Productivity Pointers, I’m going to show you how easy it is to turn your Word document into an unalterable PDF file right from within Microsoft Word. While it’s not impossible to alter a PDF file, it’s far more challenging, which is why PDF is becoming the industry standard file format for sending contracts over email.
