SIM Scan

Author: Dejan Kaljevic

SIM Scan analyzes the ATR, commands, and file structure of smart cards, and for GSM SIM cards determines the IMSI and Ki. The obtained IMSI and Ki can be written to a Gold Wafer with PIC16F84 and 24LC16.

Ki extraction repeatedly runs the A3/A8 algorithm. On SIM cards with a limit on the number of runs, this can irreversibly disable the card's authentication.
