The proxmark3 doesn’t have any chameleon mini like functionality for HID formats out of the box, so I wrote a new standalone mode to fill the gap.
You can use it with a proxmark3 and the blueshark module to quickly cycle through any number of predefined raw HID 26 Bit (H10301) UIDs offline. Check it out here (LF_MULTIHID):
Proxmark3 RFID Research Group (RRG) - Iceman Fork.
Setting a New Standalone Mode
To flash a new standalone mode:
- Copy Makefile.platform.sample to Makefile.platform
- Edit the STANDALONE variable inside Makefile.platform. Uncomment it and chose a standalone mode. For example:
PLATFORM=PM3RDV4
PLATFORM_EXTRAS=BTADDON
STANDALONE=LF_MULTIHID
- After setting the standalone mode, build and flash to the Proxmark3:
make clean
make -j
./pm3-flash-fullimage
for more information on the other standalone modes available refer to the Proxmark3 Standalone Wiki.
