Jeez, I have a flipper zero and it’s amazingly boring. I use it as a sensor for WiFi to determine strength and other metrics to improve my home WiFi. I used it once to fix a tire sensor, or rather to determine which one was bad. It’s not some hacker tool, it has a bright white case with a fluorescent orange wrap and only useful for debugging and testing things. It’s great, but not dangerous.



Just because you aren't clever enough to use it as a hacking tool doesn't also mean that others aren't. You can easily do basic things like snatch NFC data. Or duplicate the RF transmit signal for someone else's garage doors. I think if you exercise a little imagination you can see how it could be used nefariously.

And even still I would never support banning the device.


you could say the same for RPis, arduinos, or even just 555 timers -- it's still ridiculous to ban something that provides functionality that is trivial to replicate elsewhere.

the gimmick of the flipper is that it does a lot of things in one unit -- every one of those singular functions is easy to do elsewhere, and often less hobbled by the intrinsically low-power nature of the flipper.


That’s an unhelpfully overly-reductive position. Nobody is hacking garage doors with a 555.

In the same vein - AirTags are considerably easier to covertly place on someone else than other asset tracking systems. Yes you can accomplish something similar with either but the likelihood of it being used for unintended purposes increases with the convenience and ease of doing so.


> Nobody is hacking garage doors with a 555.

I'd honestly be surprised if no one has made a device to open garage doors with a 555 timer in it somewhere.


Don't garage doors use rotating keys, like car fobs?


There is alternative firmware that allows you to do some things with rolling codes. Most of the cool stuff the flipperzero can do can be found here - https://github.com/djsime1/awesome-flipperzero


Modern ones do, old ones do not


yes they do


It depends on the garage door opener.


Sure but most use rolling codes. Y'all can downvote all you like, it's still true, and downvotes won't change that.


The parent's comment was reasonably stated, and you haven't challenged its factuality. Also, you don't know that they downvoted you.

Regardless, what you said implies that no more than a negligible amount of garage doors don't use rolling codes, since the reason for my question was security related. If that's not true, I therefore wouldn't say your comment was strictly true.

All this is to say, votes up or down aren't that important. The attitude seems unwarranted.


> It’s not some hacker tool, it has a bright white case with a fluorescent orange wrap...

Sorry, but how do these aesthetics prevent it from being a hacking tool? Some cool history rebuts the notion: https://telephone-museum.org/telephone-collections/capn-crun...



It's pretty easy to use it for naughty things like brute forcing gates/garages, cloning NFC/RFID badges, turning off other people's TVs/aircons, messing with car key fobs, cloning iButton keys, etc


Some unofficial firmware forks allow replaying signals that shouldn't be replayed like signals from medical devices. You can also desync some car fobs in some cases causing someone a bit of pain to get it fixed


You can use a phone app for measuring WiFi strength.


First, a flipper zero doesn't even have built-in wifi. Only the dev board has that, and it's sketchy as well.

An android phone running Wigle or WIFIAnalyzer is plenty good for wifi.

As to "dangerous", it is unequivocally a hacker tool. Or are you arguing that this is a "testing tool"? https://github.com/UberGuidoZ/Flipper/tree/main/Sub-GHz/Gas_...
