In previous lectures and videos I've talked about safes and vaults and tried to always impress upon my audience that no storage solution is meant to be impenetrable, but rather that the job of secure storage is to slow down a potential attacker -- costing them time and effort -- such that they either give up or get detected and the proper response is put into effect quickly.
Thus, I'm a fan of safe and vault monitoring tools. Many installations include door sensors and shake sensors mounted external to a safe or vault. The use of cameras and the like in the room or just outside the area is also typical. But all of those systems (a) have a certain level of effort associated with installation and (b) often require a lot of ongoing fiddling and maintenance, especially when it comes to preventing nuisance alerts. There's also (c) the up-front and ongoing costs of operation.
For those reasons, I am feeling optimistic about this little device from Simtek. Called the StealthAlert, this tiny package includes sensors that monitor light, motion, vibration, humidity, temperature, and (by way of the included cellular connection) relatively accurate location data.
Place it in your safe, your vault, your secure room, or even your gun case (either at home or on the road) and you've got an easily-deployed way to get quick SMS alerts if anyone disturbs your items. With all the praise I'm offering here, I should remind everyone (as I do in the video) that this is not an ad and I'm not sponsored by Simtek. I bought this with my own money and I just wanted to try it out. Thus far, I like it quite a bit.
I'll report later on about things like battery life and overall performance, but for now... yeah. Looks pretty decent. This is a link if you want to know more... simtek.io/products/stealthalert
Enjoy! 👍😁👍

![Proxmark3 Blueshark-to-Android How-To-Guide, part 1: Hardware Install
There are three videos in this series. To make the details in the doobly-doo more useful Im simply replicating all my notes and links across all three. Enjoy! 👍😁👍
-
[= Video One: Hardware Install =]
1. Install the BlueShark Module
Pop open the Proxmark case, connect the Bluesharks ribbon cable, and optionally dim your LED lights if covert pocket carry is of interest to you.
You can acquire a Blueshark module either from Hacker Warehouse or from my own retail site that I dont mention on my channel because its cringe to do that shit. 😂
[= Video Two: Update Proxmark Firmware. =]
2. Flash your Proxmark to the latest firmware with the BT addon
The easiest way to go about if youre on Windows is by grabbing the latest pre-compiled bluetooth-enabled build from Gators site...
https://proxmarkbuilds.org/fileviewer.html#rdv4_bt/
If you want to fully compile from source, you can pull that from the RfidResearchGroups GitHub repo...
https://github.com/RfidResearchGroup/proxmark3
...and edit the Makefile.platform file to uncomment one line...
# If you want more than one PLATFORM_EXTRAS option, separate them by spaces:
#PLATFORM_EXTRAS=BTADDON
#PLATFORM_EXTRAS=FLASH
#PLATFORM_EXTRAS=SMARTCARD
PLATFORM_EXTRAS=BTADDON FLASH
#STANDALONE=LF_SAMYRUN
... notice how that fifth line is uncommented, thus enabling the BTADDON flash line. But for real, the precompiled binaries are a way easier choice here.
Connect your Proxmark to your laptop and run the pm3-flash-all.bat script to ensure that your device is fully up to date and that youre now running firmware that will play well with the Blueshark that youve installed.
[= Video Number Three: Connect Your Proxmark to your Android Device =]
3. You will need two tools:
Termux...
https://f-droid.org/packages/com.termux/
(yes this involves trusting an app outside of the Play Store)
Bluetooth TCP Bridge
https://play.google.com/store/apps/details?id=masar.bb
(i recommend spending the $3 for the pro version)
4. Install the Proxmark software from within Termux
There is also a guide here...
https://github.com/RfidResearchGroup/proxmark3/blob/master/doc/termux_notes.md#install-proxmark3-package-which-follows-tagged-releases
But this command should install the latest stable release...
pkg install proxmark3
You can also run this if youve re-flashed your Proxmark device elsewhere and now youre back on your phone again and want to make sure all software versions are the latest release...
pkg upgrade proxmark3
5. Pair your proxmark with your phone
Go to your Bluetooth interface in phone
Make sure the Proxmark and BlueShark are powered on (BT light should be flashing)
Add new device
Pairing with code 1234. Remember, pairing is not the same as connecting. If your Proxmark is listed in saved devices then it is paired.
6. Use the BT/TCP bridge to actually make the connection
Start Bluetooth TCP Bridge
Set the Proxmark as Device A using Connect to classic Bluetooth device
Set a TCP Server as Device B on an unused port (e.g. 4321)
Ensure Retransmission is set to both ways
(It is possible to record the config as autostart script under Settings. Hence why i like the Pro version)
7. from Termux you should now be able to connect to your proxmark
proxmark3 tcp:localhost:4321
8. Setting home screen icons, etc
If you are doing a little bit of polish and cleanup on your phones home screen, this is the link to the Blueshark icon that I have created...
https://deviating.net/stuff/Blue_Shark.png
... enjoy running your Proxmark3 device without the need for a laptop now, everybody! Keep in mind, that while loads of the usual functions that you are used to performing should work just fine, there is a slight communications lag when you are bridging over bluetooth. A few of the more advanced functions which involve very fast and timing-depending interrogation of certain credentials, readers, etc. may fail to work if youre operating in Bluetooth bridge mode like this. I have found that this is particularly true if youre in an environment with a lot of noise in the Bluetooth radio spectrum.
Good luck and Happy Pride! 👍😁👍🌈🦈
