CHAPTER Input and output devices 6 INFORMATIONINTHISCHAPTER: • Display options • Keyboards • Mice • IEEE 802.11 wireless • IEEE 802.15.4 wireless • Network hubs and switches • BeagleBone capes • Penetration testing with a single remote hacking drone INTRODUCTION In this chapter, we will discuss several standard input and output devices, which may prove useful when connected to our Beagles. We will begin with a discussion of standard items such as displays, keyboards, and mice. From there, we will move on to wireless and wired networking devices. BeagleBone expansion boards, known as capes, will also be discussed. In anticipation of our discussion of using multiple Beagles for a penetration test in the next chapter, we will finish up by rehashing our test from the previous chapter using only methods that are appropriate for remote hacking drones. DISPLAY OPTIONS It is difficult to know what a computer is doing without some sort of display. Remote drones and dropboxes don’t require displays. Unless you are remotely logging in to your Beagle via SSH or something similar, you will likely want a display if you require any interactivity. TRADITIONAL MONITORS The BeagleBoard-xM and BeagleBone Black both feature connectors for digital computer monitors or televisions. The BeagleBoard-xM sports a full-size HDMI connector. This board supports the Digital Video Interface-Digital only (DVI-D) protocol. Hacking and Penetration Testing with Low Power Devices © 2015 Elsevier Inc. All rights reserved. 123
124 CHAPTER 6 Input and output devices DVI-D is essentially identical to HDMI with the exception of supporting audio. If you want to play back audio on the BeagleBoard-xM, you must use the onboard audio jacks. The BeagleBoard-xM also features an S-Video output for connecting it to a television. The S-Video can be used for a primary or secondary monitor. The BeagleBone Black features a micro-HDMI display output. Unlike the BeagleBoard-xM, the BeagleBone Black supports the full HDMI specification, including audio. In fact, the only audio playback method supported is via HDMI. The BeagleBone Black uses electronic display identification data (EDID) provided by the monitor (or television) in order to select an appropriate video mode. The display should be connected before powering up the BeagleBone Black to ensure the EDID is properly received and to reduce the chance of damage due to electrostatic discharge. If you are traveling for a penetration test, you might be able to use the hotel television as a monitor. There would likely be some objections if you tried to take the hotel television away in your car, however. If you intend to use your monitor inside your automobile, you should seek out a monitor with a separate power brick transformer versus the standard International Electrotechnical Commission (EIC) C14 connector used in personal computers. If you can find a monitor that accepts 12 V, that would be ideal. You may be able to buy or build a DC-to-DC converter if the monitor requires something other than 12 V. A universal laptop car charger might be an option if the monitor input voltage is compatible with its available output voltages. An online search for carputer (car computer) monitors should provide several options. If you intend to run a monitor off of battery power, it pays to spend the extra money for one with LED backlighting. LED monitors are considerably more energy-efficient. It is also a good idea to turn down the brightness to the minimum value to conserve electricity. A monitor can be run from standard “wall” power in an automobile using a power inverter. A power inverter is a device that converts direct current into alternating current. If you do this, ensure that your inverter has sufficient power capacity to run the monitor and possibly your Beagle. Another unconventional option for a display is a USB monitor. These monitors are available in sizes from 3 to 11 in. LILLIPUT (http://lilliputweb.net) produces several of these monitors. Keep in mind that these are intended to be used as secondary monitors, so performance may be less than ideal. DIRECTLY ATTACHED DEVICES If you want a portable penetration testing system, such as the lunchbox system introduced earlier in this book, it might be convenient to have a monitor directly connected to your Beagle. The BeagleBoard-xM has dual LCD headers on the board for connection to an LCD screen. There are a number of LCD expansion boards available for the BeagleBoard-xM. The LCD7 is one of the more popular options (http://beagleboardtoys.info/index.php?title¼BeagleBoard-xM_LCD7). A Beagle- Board-xM plugged into an LCD7 is shown in Figure 6.1.
