You plug this little beauty into the wall and plug your monitor into the three-prong electrical jack on its tender underbelly. You also plug the Ethernet cable from your broadband modem/router/whatever into it. Finally, you hook your computer’s network jack up to the remaining jack.
Now, everytime your monitor goes to standby, this device will notice the drop in current and electrically disonnect your computer from the nasty, nasty Internet, thereby protecting you from evil hackers.
Of course, if you’re vulnerable to attack, you’re going to get nailed as soon as you turn the computer back on by the gazillions of automated worms that constantly scan the ‘net for potential targets. And, to top it all off, you can get the exact same amount of dubious security for free by just having your system go into standby mode, instead of just blanking the screen.
So, all in all, more security snake oil. But I’m sure folks will snap them up anyway — watch for the Databreaker on a television shopping channel near you!
