aminos and the worst is that it only costs around 3000$ to be able to build the package needed to crack GSM calls in less than 15 minutes!!! we are way behind :P this issue is solved in 3G nshalla eza 7ada biy3abberna :P :D
aminos Hey Jad, Exactly 3G operates under GSM but the encryption algorithm under 3G is A5\3 which uses solid 128 bit encryption(not crackable) while the 2G we have in Leb uses A5\1 uses 64 bit encryption which is vulnerable.
