Powering and concealing your Raspberry Pi or OpenWrt embedded device
The Raspberry Pi will need to be powered and plugging it into a wall outlet may not be possible in the place where you choose to conceal it. This is where a USB power bank can help you out. The Raspberry Pi is powered through a micro USB port, which can be connected to a battery. This can enable you to operate your remote testing kit for hours without the need to plug it in. This scenario was tested with a 6000mAh power bank, and it was able to run with the RPi and the attached Alfa USB wireless adapter for nearly 8 hours. Your mileage may vary and larger power banks are available out there, but this is a viable way to be able to drop off the Pi in the morning and complete your penetration test before having to retrieve the unit from the target.
It can be a little bulky if you have a larger wireless adapter, Raspberry Pi, and a battery to run everything; however, it's a great addition to your penetration testing tool kit...
