I’ve had one of these guys sitting around for a while - love the hardware, love the concept, but I haven’t really found a lot of use for it - what are y’all using them for?

A bit different than the other replies, but I'm using mine like a very extensible input/output device for my own hardware projects and as a general STM board for fiddling with embedded on an STM chip (I usually stick to RP2040s and ESPs). I'm really interested in making expansion boards for the Flipper, especially ones built on the RP2040. Just sounds like a ton of fun.

My friend found out the school he sysadmins for was using weak rfid card keys (despite the readers being smart enough to handle higher level encryption) and found he could clone his key and get in places. So basically he pen tested and then they decided to upgrade to the less or non-cloneable card keys. Security for the win.

Before anyone tries this, doing this without first checking with security/facilities would likely be grounds for “disciplinary action, up to and including termination”

Unfortunately, it sounds potentially criminal, as well.

Tools can be used for good and bad. This isn’t anything new and doesn’t “ruin” a device.

The person you're responding to probably means that bad actors will cause the device to become illegal to buy or use in certain areas as a result of being associated with illegal or harmful behavior.

It’s already banned in Brazil, for instance

I got one not too long after the official launch and I've used it a decent amount (granted I am in cybersecurity and have a more real-world use cases then the average person). My favorite use case is the IR remote since phones no longer have IR blasters. It's saved me twice so far in having to buy/find a remote for something.

One thing people don't realize is that the custom firmware [0] that you can run allows you to receive and transmit on a wide range of frequencies under 1Ghz. Lots of things use that range (garage doors, gates, fan remotes, etc.) and are not very secure. I think that this will be a time looked back on where it's possible to interact with those devices without having to buy a custom PCB transmitter or somewhat expensive and complex SDR.

I countered the statement and also getting down voted. The key is to train your brain to like down votes just as much as up votes. When the number is just a number not attached to dopamine then you are free.

The votes are not there for your benefit - they're there to make good/useful/valuable comments rise to the top, and bad/low-value/spam ones fall to the bottom.

I agree with the second part of your statement. There is a real brain chemical benefit to the votes though.

Termination is a favor if security is that lax.

> Termination is a favor

Losing your job is never a favour. Would you prefer termination if any issue was found with your work place?

The M5Stack Cardputer seems like it would scratch the same itch as the Flipper Zero.

the whole point of the flipper is the sub-1ghz radio and nfc/rfid capabilities. It's not really intended to be used as a general purpose computer, it's more like a really extensible radio

Yeah, but for me (and I imagine a lot of people on here) the itch that Flipper Zero teases is that of a hackable computer in a neat form factor, not the specific radio capabilities that it's actually meant for.

I didn't know about M5 before and now I'm hooked exploring M5's store, so I appreciate OP's pointing me there!

$169 is a bit steep for me, so I went on Temu and bought a $8 125KHz RFID programmer & a $5 USB-C IR Blaster. Combined with my Samsung phones native NFC writing, bluetooth, etc I feel like it scratched the itch of 90% of what people do with Flipper for 10% the cost.

The point of the flipper zero is to have one good supported gadget that has a lot of people hacking away with it.

It's the same thing with the raspberry pi, sure you can get some cheap clone off less than ideal places, but you're gonna pay with your time. That's basically it.

If you want to go deeper with RFID and can spend a bit more (~$50), I am pretty happy with my knockoff Proxmark3 Easy [0] I got on ebay. (Do some research to find a good seller as I have heard some sellers ship bad units). It can do both 125khz and 13.25Mhz RFID/NFC and is easier to use then some of the Android apps for cracking Mifare keys.

For the price, it is great for more complex attacks and almost has all the features of a full Proxmark RDV4 (minus BLE and a battery).

Apart from access control systems, it hardly has any good uses in the real world as a pen-testing device. If it was a pocket carry, true SDR, capable of recording RF signals as I/Q, performing actions on them, replaying them, etc, it would have justified its cost. But, with a limited set of modulations supported by the used RF chips, it is more like a toy for hacker wanna-be teenagers than a serious tool. An investme…

Totally agree that this isn't a good full pentesting device, but I also think that such a device doesn't need to be in order to be popular. Just look at the IM-ME when Samy Kamkar showed it off [0] and it sold out.

Most people don't need a full SDR like a HackRF in order to explore their RF devices and a Flipper gives that too them without the headache of software and the bulk of a full PortaPack.

(I love my HackRF and PortaPack for the record. The Flipper can't complete with the features and low-level access when you need it)
