"Flipper Zero can't be used to hijack any car, specifically the ones produced after the 1990s, since their security systems have rolling codes," Flipper Devices COO Alex Kulagin told BleepingComputer.
"Also, it'd require actively blocking the signal from the owner to catch the original signal, which Flipper Zero's hardware is incapable of doing.
Just politicians trying to appear to be doing something so they can keep their jobs.
Yes, but even if the base model hardware is incapable of doing something, someone savvy enough could modify it. It's the same logic they use to ban AR-15s in some states in the US. By default, all civilian ARs are built to fire in semi-auto only, BUT, a knowledgeable individual can make it fire in full auto if they drill a hole in the lower receiver in just the right spot.
Edit: Okay, I'm getting roasted for pointing out that no system is 100% secure against malicious actors? Perhaps you're missing my point that I disagree with banning Flipper Zero and fully believe it's Canadian politicians looking like they're doing something, regardless of whether or not it will actually work.
Good point in general, but, what they're specifically talking about here (rolling codes), perhaps what they should have said is that no one can (feasibly) do it, not just that their hardware isn't capable.
Edit: Oh, for the blocking signal, that part might be functionality that could be added, I see what I think you're saying there. Still, that would be a step towards it, but it would still require serious hardware to crack a private key, as I understand.
Are people downvoting this because you made a fair comparison between something they like (flipper) and something they don’t (guns)? Like are you being downvoted out of cognitive dissonance?
Monoxide means one oxygen which means free radical, which is basically what car thieves are too. So you're right, clearly all this wanton consumption of this chemical must be stopped.
Lol. You better just ban all programmable boards then, because the Flipper doesn't have any special proprietary or differential tech in it. It's just a clever collection of already existing hardware and software. Someone will just make another immediately. Idiots.
I don't disagree with your point, but the flipper zero for sure lowers the bar of entry. Before the flipper came out the, "You must be this tall to ride" required some pretty good knowledge of microcontrollers, hardware peripherals, and software engineering. The people that had that sort of knowledge tended to actually have paying jobs, which is like the biggest factor in not being a street criminal.
The flipper made the barrier of entry at about the level of being able to operate a TV remote which any dipshit can do. However, the fact that the flipper exists at all means that the cat is out of the bag. As you said, someone else is just going to come along and release a similar product. You can't just ban the flipper and expect it to have any impact. My concern is they will decided to make certain code illegal, which gets really stupid.
Barrier to entry to do what? They can't be used for vehicle theft because you can't replay attack a rolling code, which is what all vehicles use.
The current attack is to use a repeater to amplify a fob that's close enough to an outside wall to hijack and open these "get close enough and the doors open" locks.
The Flipper is literally just an ends to a means. An easily accessible action for hardware. Nobody is stopping any random person from buying a number of $3 dongles for their laptop and using it in the exact same way.
Bar for entry wasn’t really that high to begin with. There were already a collection of tools that did the same thing, and could be had for a couple thousand bucks. Yeah, a price point 1/10th the older option is more accessible, but it’s not like criminals are hurting for money just because they are criminals.
I saw this on Mastodon the other day and started digging into it. Seems like a really cool project although the chip they used appears inferior to the ESP32? I found a few similar projects based on the ESP32 but they seem to be limited to wifi/bluetooth captures only with the possibility of other options if you swap out the firmware. This makes me question why the ESP32 with 4MB of flash cannot do much more than the Flipper Zero with its 1MB of flash and a CPU that runs at 1/3 the speed (or less) and only a single core? Anyone have some ideas, and/or have seen other open projects based on the ESP32 that do all and more that the Flipper Zero can do?
Yeah I saw there was the add-on board for wifi testing, but it seemed like this plugs in externally and isn't a normal part of the toolkit? So if the Flipper itself isn't performing the wifi test then I guess I don't see why the ESP32 couldn't just add in everything else the Flipper does? All the other hardware I saw, for IR, NFC, RFID, and one-wire connections... that could all easily also be added to the ESP32 with pins to spare, so what am I missing?
Meshtastic commes to mind, it allows you to set up an offgrid communications network that can mesh with other devices and allow you to send messages through the netork.
Yeah I wasn't too concerned about the hardware side of things, I was just curious about finding software because I don't really know anything about pentesting. Guess I'll keep looking around.
The ESP32s are nice chips, but the STM32s are also really nice to work with and will work fine for this task. Changing to an ESP32 wouldn't make any real difference to the user so the choice is moot really.
I've designed products around both CPUs and they're both pretty nice. The STM32 has somewhat better documentation, has cleaner low power modes and is a bit simpler when delving into the nitty gritty details. The ESP is more powerful and has some nice if complex features but I don't like its low power handling as much.
Overall I think I'd choose the STM32 for this task since it's a little easier to make small, battery powered devices with it.
From the limited reading I've done on the subject, it seemed like a lot of power in the Flipper was based around wireless testing (both wifi and bluetooth) although I also saw a number of things based around other bands. I guess I'm just not following why this was considered an add-on when the ESP32 has all that stuff built in already (and you can certainly shut down the radios to save power when you're not using them)? Plus it also includes native support for other popular busses like I2C, I2S, and CAN so it seems like it could be useful for sniffing out what's attached to a lot of different types of connections. Maybe I'm just straying outside the realm of basic pentesting, the idea just caught my attention about how handy it might be to have a small device that could work with a lot of different types of electronics.
