| Titre | Hacking the Microsoft Sculpt keyboard |
| Texte |  In its infinite wisdom, Microsoft designed data encryption into the Sculpt wireless keyboard set to protect against wireless eavesdropping and other attacks. The keyboard allegedly* uses AES for symmetric encryption with a secret key burnt into the chips in the keyboard's very low power radio transmitter and the matching USB dongle receiver during manufacture: they are permanently paired together. The matching Sculpt mouse and Sculpt numeric keypad use the same dongle and both are presumably keyed and paired in the same way as the keyboard.This design is more secure but less convenient than, say, Bluetooth pairing. The risk of hackers intercepting and successfully decoding my keypresses wirelessly is effectively zero. Nice! Unfortunately, the keyboard, keypad and mouse are all utterly dependent on the corresponding USB dongle, creating an availability issue. Being RF-based, RF jamming would be another availability threat. Furthermore, I'm still vulnerable to upstream and downstream hacking - upstream meaning someone coercing or fooling me into particular activities such as typing-in specific character sequences (perhaps cribs for cryptanalysis), and downstream including phishers, keyloggers and other malware with access to the decrypted key codes etc.So yesterday, after many, many happy hours of use, my Sculpt's unreliable Ctrl key and worn-out wrist rest finally got to me. I found another good-as-new Sculpt keyboard in the junkpile, but it was missing its critical USB dongle. The solution was to open up both keyboards and swap the coded transmitter from the old to the new keyboard - a simple 20 minute hardware hack.In case I ever need to do it again, or for anyone else in the same situation, here are the detailed instructions:Assemble the tools required: a small cross-head screwdriver; a stainless steel dental pick or small flat-head screwdriver; a plastic spudger or larger flat-head screwdriver (optional); a strong magnet (optional). Start with the old keyboard. Peel off the 5 rubber feet under the keyboard, revealing 5 small screws. Set the feet aside to reapply later.Remove all 5 screws. Note: the 3 screws under the wrist rest are slightly longer than the others, so keep them separate.Carefully ease the wrist rest away from the base. It is a 'snap-fit' piece. I found I could lever it off using my thumbs at the left or right sides, then gradually work around the edge releasing it. You may prefer to use the spudger. It will flex a fair bit but it is surprisingly strong.Under the wrist rest are anot |
