View Full Version : Write IMSI & KI on SIM CARD.
Is it possible to WRITE IMSI & KI on a NORMAL SIMCARD ???
If yes, HOW?!
Someone told me that the SIM card is a PROM ...but i haven't confirmed that yet
No... I don't agree...
They should more probably have used a method similar to the one used by satellite cards manufacturers to assign the ISSUER KEY (that has nothing to do with descrambling) to the card.
That key is writte in a special memory in RAM but that zone is protected by the simple fact that no instruction can read from there..
The problem is that many satellite cards have bugs (buffer under/overflows) that allow to cheat the card and read that key.

P.S.
Most probably they just put it in a even easier way...
security by obscurity :)
if we can read it then we can write it !!
what processor and memory r we dealing with ..
like the gold card is P I C16f84 and 24c16
any idea ???
