GSM
The aim of the project is to improve functionality of OpenBTS software. USRP hardware is quite expensive.But our friends PiSec Hackerspace have one and we have possible remote access. It would be a good idea to share it between more people. Hackerspace could be ideal place to do that.
Goals of the Project
- improve our knowledge of GSM networks at all ;)
- security research in GSM area
Status and Plan
The project is currently in the active stage.
- [DONE] gsmbox - 8 osmocom compatible phones in one box with only USB as I/O.
- [DONE] Run Kraken so we will be able to crack A5/1
- Tune utilities for data capture
- Tune Kraken (speedup, hardware, …)
- GUI ?;)
GSM Shield
This shield is used in combination with FT4232HQMiniModule to attach 4 Motorola C series GSM phones to computer using 4 serial connections.
Material recomended:
- FT4232HQMiniModule (sos.sk, farnell.com)
- 4x 2.5mm audio-jack (ges.cz)
- tip - TX, 2nd ring - RX, rest - GND
- Standard 2.5 mm jacks are just too big ;(
- FT4232H Shield - git repo
- This shield is not necessary, but makes whole construction much more robust.
When assembled, it should look somehow like this:
GSM box
Basic idea is to put multiple (8) phones into 3,5” HDD box. Only one usb cable as interface.
TODO:
- assign a separate page to it
- design & make “holder” for phones inside the box (use rep-rap) ⇒ use smaller box.
- remove filters from phones, so we can sniff upstream better
