What is Flipper-ARF?

Flipper-ARF is a C firmware fork for Flipper Zero, stripped down for automotive research on Sub-GHz protocols. It handles decoding, encoding, and emulation for keyfobs from VAG, PSA, Ford, Kia, and gates like Keeloq, with tools for scanning, counter brute-forcing, and decrypting signals like PSA XTEA. Flash via `./fbt COMPACT=1 DEBUG=0 updater_package` for a lean build focused on rolling codes and RKE systems.

Why is it gaining traction?

It excels in OEM-specific protocol accuracy—AM/FM modulations, CRC checks—without Unleashed Firmware's extras, letting users mod-hop frequencies or manage Keeloq keys directly. Academic citations ground its encoders/decoders, and debug apps test BT, CCID, display, and crashes for reliable fieldwork. Niche depth draws security folks over generic firmwares.

Who should use this?

Automotive pentesters auditing keyless entry flaws, researchers replaying RollJam on PSA/Ford remotes, or hobbyists cloning Subaru/Mazda fobs ethically. Ideal for academic studies of RKE cryptanalysis, not casual Sub-GHz play.

Verdict

Grab it for targeted automotive protocol work—strong docs and protocol tables shine—but 48 stars and 0.7% credibility score signal early-stage maturity; test thoroughly before field use. Pairs well with cited papers for responsible research.
