1/5 Another significant capture in #Ukraine. Reported discovery today of a #SIMBox being used to relay Voice calls & SMS and other info to Russian forces (including top leadership of Russian army) & other individuals in #Ukraine. I will explain what this is and how it works.

First the system is comprised of 3 main parts,
1) the SIM Box server - in this case a Hypertone SMB-128 . This handles the control of up to 128 SIM Cards, cycles them when detected etc , and co-ordinates interaction with the #GSM Gateways

- There are 3x GoIP 8 - VoIP Gateway for 8 Channels being used,
- along with 1x GoIP-4 4 SIM VoIP GSM Gateway.
Both can be used for SMS or Voice
