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

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.

Flipper Zero GPIO

 

With the default firmware, it can emulate remotes for popular garage doors and barriers, but the Flipper Zero is quite versatile and customizable, so it can be used as a signal analyzer, a U2F security token, an infrared transceiver, a “bad” USB drive for red team hacking, a generic hardware hacking tool thanks to the I/Os it exposes, and the list goes on.

The Flipper Zero’s firmware was supposed to be open-source after shipping started, but the relevant GitHub account is still empty [Update: the account has changed, and all information can be found in the flipperdevices account]. The firmware itself can be downloaded from the website. The documentation looks thorough, and the SDK for Arduino and PlatformIO+VSCode can be found in the developer section. The Verge did note that finding apps for the Flipper Zero involves looking for various projects on GitHub, at least so far, as now or soon around 100 free apps can be installed on the hacking device using the Android or iOS app, and you’ll find the source code for each app there by clicking on the GitHub link provided, for example, the “all-the-plugins” repository.

Flipper Zero App Store

The Flipper Zero started shipping to backers in January 2022, but it took a while before everyone/most got their device. Now the company says they’ve shipped 350,000 devices, and I assume many people are just using those as universal remote controls be it as a car key, to control house appliances, or open a garage door. The hacking tool can also be used as a credit card skimming device and other nefarious use cases so it’s not without its own controversies. The Flipper Zero can still be purchased for $169 plus shipping.

As a device owner from the first production run, I can confirm The Flipper Zero firmware source has been available from the start. The relevant github Org / accounts has been findable directly from their documentation.
