During an engagement last year, I was able to perform some Indala badge cloning for access.
macOS Indala Badge Cloning – Introduction
Unlike my last post, I wanted to get everything working in macOS.
The Proxmark Wiki has a guide for getting everything working, so that was helpful.
Also, I love playing the dongle game with my MBP!
Installing the Proxmark Project
First, I added the Proxmark tap to my homebrew.
rays-mbp:cpscam doyler$ brew tap proxmark/proxmark3 Updating Homebrew... ==> Auto-updated Homebrew! Updated 2 taps (caskroom/cask, homebrew/core). ==> Updated Formulae apache-geode node wireguard-tools ==> Tapping proxmark/proxmark3 Cloning into '/usr/local/Homebrew/Library/Taps/proxmark/homebrew-proxmark3'... remote: Counting objects: 6, done. remote: Compressing objects: 100% (6/6), done. remote: Total 6 (delta 0), reused 3 (delta 0), pack-reused 0 Unpacking objects: 100% (6/6), done. Tapped 2 formulae (32 files, 27.7KB)
Then, with that completed, I ran “brew install proxmark3”, and installed the software.
With the software installed, I found the usbmodem device and started proxmark.
rays-mbp:cpscam doyler$ ls /dev/cu* /dev/cu.Bluetooth-Incoming-Port /dev/cu.lpss-serial1 /dev/cu.lpss-serial2 /dev/cu.usbmodem14121 rays-mbp:cpscam doyler$ proxmark3 proxmark3 proxmark3-flasher rays-mbp:cpscam doyler$ proxmark3 /dev/cu.usbmodem14121 #db# Prox/RFID mark3 RFID instrument #db# bootrom: svn 756 2013-07-13 08:11:47 #db# os: svn 756 2013-07-13 08:11:52 #db# FPGA image built on 2012/ 1/ 6 at 15:27:56 proxmark3>
Once the software was running, I ran the “hw version” command to verify that it was working and that the version information was correct.
proxmark3> hw version #db# Prox/RFID mark3 RFID instrument #db# bootrom: svn 756 2013-07-13 08:11:47 #db# os: svn 756 2013-07-13 08:11:52 #db# FPGA image built on 2012/ 1/ 6 at 15:27:56
Reading and Cloning the Badge
With everything configured, it was time to read my badge.
Note that this is how the badge actually looked, with no real photograph. I mentioned this to the client as well, but they were already aware.
proxmark3> lf read #db# buffer samples: 44 92 43 92 43 92 43 92 ... Reading 39999 bytes from device memory Data fetched proxmark3> data samples 2000 Reading 2000 bytes from device memory Data fetched proxmark3> lf indala demod proxmark3> lf indala read #db# buffer samples: 5f b0 5f b1 5f b0 5f b0 ... BitLen: 64 Indala UID=0000000000000000 0000000000000111 0111100000110001 0100001000010101 (778314215)
Once I had the badge’s UID, I wrote it to a blank card.
proxmark3> lf indala clone 778314215 Cloning 64bit tag with UID 778314215 #db# DONE!
Finally, I verified that the cloning was successful by reading the card blank!
proxmark3> lf indala read #db# buffer samples: 8f 5b 8e 5a 8f 5b 8f 5b ... BitLen: 64 Indala UID=0000000000000000 0000000000000111 0111100000110001 0100001000010101 (778314215)
Testing the Clone
Finally, with everything completed, it was time to test my badge.
I went up to a room that I knew I already had access to, and approached the reader.
As expected, it beeped, the light turned green, and I was able to get access to the room!
OSX Indala Badge Cloning – Conclusion
While cloning this badge wasn’t necessary to complete my engagement, it was good to learn about this card type as well.
The client thought it was pretty funny, and they were happy when I mentioned it to them.
I’m glad that I have the software running in macOS now, as that is my primary engagement laptop.
Finally, I hope that I am able to clone some more badges in the future!
