13:01 Androidsmartphone is turned into a fake usbkeyboard | |
| The hacker conference Black Hat DC security professionals from the American University George Mason showed a relatively new way of breaking the PC, which reprogrammed Android-smartphone with USB connection for impersonating another USB HID device such as a keyboard. In this case, from a smartphone can run on the execution of various commands, including install malicious software. Similar way, the USB can be attacked one smartphone with another, through a specially modified USB-cable. Hacking exposed Windows and Macintosh (which automatically activate any device connected via USB with a minimum indication), and Linux (which generally is not informed about a new device). In the case of Mac attacker can quickly remove the pop-up message on the screen using svezhepodklyuchennogo devaysa, and a Windows popup message itself disappears after 1-2 seconds. Practical way of this method of attack, however, is minimal, because it requires physical access to the victim's computer, and if such access is, the same effect can usually be achieved simply typing on a conventional keyboard. On the other hand, you can write a virus that will spread to each new USB phone and PC. Antivirus is very difficult to deal with this type of attack, because you can not filter the USB-traffic and to distinguish this keyboard from the "fake" or understand what behavior is "keyboard" is harmful. These methods were used crack before. For example, in April 2010, experts from the Royal Military College of Canada demonstrated a modified USB-keyboard with built-in chip that serves as a Trojan. | |
