I too would like to know how to make a hog finder
Edit: Okay I think I figured it out. Using an app called BLE Radar (F-Droid Link and Google Play link) you can scan nearby Bluetooth devices passively. You can use the app to setup filters to send notifications when specific devices or addresses are nearby.
Yup, that's it. BLE Radar is the best app I've found so far. Someone go make a PR for playing a sound when a profile matches though...
Tasers, bodycams and holsters among other things made by Taser are constantly spamming advertising packets over BLE in order to be able to link to each other quickly (ie if a taser or gun is drawn, turn on the body cam). These devices are almost all made by one company and per the Bluetooth specification, the manufacturer ID is the first three bytes of the device ID, 00:25:DF: the address for Axon International Torture Devices.

A couple notes in practice: without dedicated hardware BLE advertising packets are very random, your phone can only sense one of the three advertising channels at once and it rotates though them. Additionally local band conditions (how many innocuous BLE devices are also around, WiFi, unrelated ISM stuff, other factors) can change sensitivity. BLE is a chaotic spammy protocol that likes to shout over itself. As a result, detections can happen the instant someone gets within ~100m of you, or they may not be detected for several seconds. Some departments may not even use Axon hardware at all, though the majority seem to. You may be able to use the WiGLE database to get a sense for your locale, but I haven't dug into that yet.
Further research: This has a lot of potential for protest/protected first amendment activities. As stated, the ability to cue an audio alert. Apps that can trigger audio/video recording when cops are very close (high RSSI). Apps that can alert a friend that lots of cops are very close and the user is unable to halt a countdown. Apps that can wipe/lock/turn off a phone if lots of cops are very close or around for an extended period of time (in custody).
This is cyberpunk as hell, and awesome.
Unfortunately apple does not expose mac addresses to apps, so iPhone users can’t do it :(
Is there anything iphones can do besides scroll social media? Every time I hear about some cool new capability of phones this caveat is always present.
Complain about how blurry their 60 second video came through and blame it on android. I constantly explain how iMessage isn't texting, but there are plenty of ways to get the same abilities.
This is why I'm on Lemmy
Unfortunately, this requires your local police department to have the latest axon gear… I’ve actively sat down and listened for signals near my local police and didn’t spot any advertising beacons
@ackshewally There's also D4:2D:C5 for i-PRO & a bunch for Motorola Solutions Inc. (different child company from Motorola, seems to make police hardware). Does anyone know any more OUIs? There are a few other Bluetooth police hardware manufacturers I've found that don't seem to have OUIs.
Also, does using an asterisk like that work? I've been using a regex for it & I would like to turn it into that to make it more readable.
I wish there was something better than BLE Radar for this that could search for things other than just MAC addresses & preset manufacturers.
Wait could I theoretically go to a UK police station or somewhere with a lot of police and pick up their MAC addresses.
Then if I were to be involved in some direct action I could get alerts that the police are nearby?
If so what device do I need to do this mobile? Like a laptop? Or one of those little orange hacker tools which the name is escapes me right now.
Flipper
That’s it. Gone I’m getting old. Flipper Zero init.
Do you have one? I’ve been interested for a minute but not sure if I can loads of fun with it.
I’d be interested in using it to affect digital billboards or taking direct action against companies I don’t think have a moral backbone.
While flipper is very versatile, it's pretty weak compared to dedicated devices with proper antennas for the signal type you're looking at.
Thanks that helps me make the choice.
I do already have some decent antennas from the last time I was playing around with Kali and Airpdump ng so I’ll get into some studying.
Thanks.
I looked into maybe getting a flipper a while back and decided the hackRF would be the way to go. I never got either, but from what I was reading, hackRF let's you do all the things people who own flippers wish the flipper did.
Yeah I think GhostStrats on YouTube did an episode on his toolkit and the HackRF was recommended.
What I really want to do is fuck with digital billboards. I have a hatred for adverts and more so in the real world lol.
