Wireless keyboard hacking has become popular again since Kali released Nethunter and other tools such as Keysweeper.
These hacks are nothing new, and many keyboard manufacturers have begun to encrypt wireless keyboard signals with the AES algorithm.
The bad news is many cheap off-the-shelf keyboards do not encrypt the signal.
How Do These Hacks Work?
Sniffers are used to seek out and grab any keys that are typed into a keyboard. Some of these sniffers work on smartphones, with the tool Nethunter turning an Android phone into a wireless keyboard sniffer.
Some hackers use antennas to pick up a signal and decode it. This is the most common approach to use specialized radio equipment to pick up wireless signals from a distance and then decode them.
While other ways are to place a seemingly harmless device such as a USB wall charger in a home which will store all the keyboard strokes. Many of these will also boost the wireless signal so that it can be sent to a hacker; advanced ones use a SIM card and the cell phone network.
So What Does This All Mean?
Some wireless keyboards are encrypted between the USB adapter and the keyboard while some are not. So if you care about passwords, credit card information, or any critical data entered into a keyboard, buying a secure wireless keyboard is a good idea for security.
How Do You Buy a Secure Wireless Keyboard
This one is simple, be sure it uses the AES encryption algorithm. Any keyboard that transmits in the clear will be easily hacked.
Some keyboards take it a step farther, such as not using the 2.4GHz range and proprietary security, which make them more expensive.
Below are examples of secure wireless keyboards with AES Encryption.
Before buying a new keyboard be sure to check if the one you are using has AES built-in.
As always be sure to read the reviews on Amazon, forums, here, or elsewhere to be sure a unit is a good fit for you.
