Staff is not made aware of this intentionally. Wireless keyboards vs wired, how many Microsoft or Logitech mice. I can tell you everyone that has an iphone, android or other “device” on the system, even just charging. We use something like this in our office. The issue there is security like this isn’t commonly advertised in a network so you might find-out the first time you connect something. Yes turning off the host and placing this in place “could” work. Especially when the secure network should not have any changes that are unapproved.In this case a change (new device detection/re-detection) would cause the network to sandbox the host. Then upon additions, removal, or changes IE unplug keyboard plug in emulator that has same ID and even SN, you can easily identify what is going on. One can look for changes, say calls to enumerate devices. By using software one is able to monitor in real-time all usb attached in a network. You will see provisions for serial numbers, device ID’s and all sorts of ways to fingerprint devices. Posted in Security Hacks Tagged security, Teensy, usb hid Post navigation This executable is a bare-bones application that can send any file back over the USB cable to the Teensy where it’s stored on an SD card. Short of filling the USB ports in a workstation with epoxy, there’s really no way to prevent secure files from leaking out of a computer. After opening up Notepad, mashes the Caps Lock key to force the Teensy to type out a script that can be made into an executable. To extract data from a system, connects a Teensy microcontroller to the USB port. ’s build exploits the USB HID protocol, but instead of 1 bit per second, he’s getting about 10kBps. Previously, the best method was to blink the Caps Lock LED on a keyboard, sending one bit at a time to a micocontroller. We’ve seen this sort of thing before where a microcontroller carries an executable to extract data. came up with a way of dumping files onto an SD card by using the USB HID protocol. Security is a cat and mouse game, so of course there’s a way around these measures. One of these is disabling any USB flash drives that may find their way into a system’s USB port. High security workstations have some pretty peculiar ways of securing data.
