Once upon a time, a photograph provided only the information one could see in the physical print—no hidden data about locations, time and date, or the device that took the photo.
With the advent of easy digital photography, however, connecting extra information to the photos became easy as well. This information, known as “metadata,” might include items like the GPS coordinates of the photo’s location, the date and time it was taken, the camera type and shutter settings, and the software used to edit the photo.
Many digital photographers don’t realize that their photos might carry this...
Mention “cookies,” and most people expect a treat to appear. When talking about computers, however, cookies aren’t what’s on the dessert menu. In fact, they’re not even physical objects. Yet they do a great deal of the work that makes it possible for you to browse the Internet—and they can cause trouble if you don’t know how to manage them.

A computer “cookie” is more formally known as an HTTP cookie, a web cookie, an Internet cookie, or a browser cookie. The name is a shorter version of “magic cookie,” which is a term for a packet of data that a computer receives, then s...

But what does that have to do with your computer?
Have you ever run your Internet security software only to find out that there’s malware on your computer? How did it get there? When you’re running a full Internet security suite, it can be very frustrating to find out that, despite your best efforts, there’s malware on your computer anyway. The fight against malware is a complicated arms race of sorts. Here’s how it works.
The Four Components of the Malware Arms Race
There are three main players in the malware arms race:
The malware coders are, unfortunately, generally the winners of the arms race. They write mali...
Did you know that an attacker can flood your house via the water dispenser on your connected refrigerator? Or that bluetooth enabled locks can be picked from ¼ of a mile away using radio frequencies? I didn’t either, until I attended this year’s DefCon 24, an annual hacking convention in Las Vegas.
While a hotel in Las Vegas full of 22,000 hackers sounds like it might not be a good idea, it’s just the opposite. The purpose of this conference is to bring together Internet security professionals from all over the world to help educate, inform and learn how to make the Internet a safer place...
