What do you guys use for extracting and looking at the hex of a SIM?

USIM Detective has the capability to record the APDU requests sent to the card and the data that is returned. All in hex too !

Where is the usual location of the PIN and PUK code please on a SIM Card?

The SIM is a logical device, so when you are "reading" the card, you are sending requests to the SIM and it is replying.

It isn't a "hex dump" where you're seeing all the data from start to finish. You'll have to ask the SIM for its PIN. I have a feeling that it won't tell you!

triran, I think you may have read the threads below before but overlooked them - have a read

http//www.forensicfocus.com/index.php?name=Forums&file=viewtopic&t=3349

I also started a student library of images at FF dotted about the threads in the mobile phone forensics forum. If you look at the images of Proactive SIM you will see some answers to your question

Lastly, three other points

- Not every SIM Manufacturer reveals the EF containing the address for PIN validation; not every SIM reader reveals all the EFs in tree under the Master File on SIM / USIM.

- AlexC makes good observations relating to PIN. I do use a bit-nibbler also when needed.

- Lastly, if your question is leading to "is it possible during a read to reveal the PIN of a SIM or does the EF file header assist?" then of course you are asking for the answer to the SIM PIN Challenge connected with the first link above.
