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”

I don't know why you're getting downvoted for this. It's 100% correct advice. The person you're replying to is a sysadmin so they are probably okay in this situation but cloning access cards without permission would be a serious breach no matter how well intentioned or how easy.

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 investment in something like HackRF+PortaPack clone is far better, IMHO.

I really resent the marketing of this product. It's as if they invented the cheap RF chips they're using and are the exclusive distributors of it. It's rubbed me as thoroughly dishonest and fraudulent. I know this is currently a minority position, that's why I took the time to state it.

Really? I like mine. Learned a lot about RFID and was able to successfully copy and clone some hotel prox card. Sure, they didn't "invent" the chips inside, but they put the hardware and software in a nice package, included software, and grew a nice community of hackers around it. Because of the popularity of the device, there are third parties, some less reputable than others, trying to ride their coattails. Perhaps…

I was able to clone my apartment fob using a tool I got for $30 on Amazon, and it even came with extra blank fobs and cards to clone to. Flipper Zero can more than just clone RFID keys, but my point is that the tools exist to do all the things it does and do them cheaper, and they're just as easy to use.

If you really need a tool that can do them all, though, I can't really argue with the utility; but I do kind of agree with the GP comment that Flipper didn't exactly do anything that hasn't been done before.

They made a product that’s really easy to use out of a bunch off of the shelf components. What’s fraudulent about that? I haven’t seen them claim any features that the device doesn’t have. They literally have the chip product numbers they use for each module on their home page! They’re not hiding it!

If only issuing clone-able key cards were the infraction instead...

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.
