Flipper Zero hardware & wireless hacking tool gets an app “store” with open-source app

Flipper Zero

Flipper Zero portable multi-tool for pentesters and hardware hackers has now gotten an app “store” with currently around 100 free and open-source apps available through the device’s Android or iOS app. I missed it at the time, but the Flipper Zero launched on Kickstarter in July 2020 and was massively popular with close to 5 million dollars raised from almost 38,000 backers. The tool looks like a toy but it allows hacking with GPIOs and short-range wireless protocols such as Bluetooth, RFID, NFC, and infrared.

The Wi-R protocol relies on body for data communication, consumes up to 100x less than Bluetooth

Wi-R vs Bluetooth

The Wi-R protocol is a non-radiative near-field communication technology that uses Electro-Quasistatic (EQS) fields for communication enabling the body to be used as a conductor and that consumes up to 100x less energy per bit compared to Bluetooth. In a sense, Wi-R combines wireless and wired communication. Wi-R itself only has a wireless range of 5 to 10cm, but since it also uses the body to which the Wi-R device is attached, the range on the conductor is up to 5 meters. While traditional wireless solutions like Bluetooth create a 5 to 10-meter field around a person, the Wi-R protocol creates a body area network (BAN) that could be used to connect a smartphone to a pacemaker, smartwatch, and/or headphones with higher security/privacy and longer battery life.   One of the first Wi-R chips is Ixana YR11 with up to 1Mbps data rate, and they are working on a YR21 […]
