| | | | | Ultrasonic AlarmUSB - Protect your data when you leave | | | The Ultrasonic AlarmUSB is a device designed to guard your computer and the data stored on it during periods of time when you leave your computer running but you are not there to prevent a potential attack. It is the best means of defense against a 'Cold Boot Attack'. This type of attack enables the retrieval of encryption keys from a running operating system after using a cold reboot. A cold boot means the machines power supply is cycled "off" then "on" without letting the computer shut down cleanly. Next a light-weight operating system is booted, and the contents of pre-boot memory dumped to a file. The memory modules can also be removed from the attacked machine and placed in another one. The data can then be accessed from this second computer. This attack relies on the fact that you can retrieve memory contents from DRAM after power has been cut off as they remain readable for minutes. This window can be if the modules are cooled. Furthermore, the bits can be reconstructed after they disappear because they fade away in a predictable manner. | | |
