Greg Smith at TrewMTE has posted an interesting challenge. If you've ever done in-depth work on a SIM card, this may be right up your alley.

So does that mean a particular EF under the MF in SIM with a logical address 3F00 0000 is always going to be the CHV1 file and would the raw data from that EF reveal a user's PIN number?
.
Below are raw data extracts from three phases of SIM cards - Phase 1, Phase 2 and Phase 3 (2+) and harvested from the Master File (MF) 3F00 and an unnamed EF immediately under the MF with an addess 3F00 0000.
.
Your challenge, if you are interested, is to examine the raw data and corroborate whether the data reveals a user's CHV1 (PIN number) or not.
