Exploiting GSM Vulnerabilities: An Experimental Setup And Procedure To Map TMSI And Mobile Number
sanjeev saharan, Jitender Kumar · International Journal of Advanced Research in Computer Science · 2017
This research paper aims to correlate mobile phone number and TMSI in the GSM cellular network by incorporating advantage of mobile network operator not updating TMSI so frequently with each new service.Silent call procedure is implemented using Arduino board with gsm module sim900.For each network silent call timing is calculated by measuring call completion time and ringing time.So without alerting on the phone of the victim, its phone is forced to receive paging request and this paging request contains TMSI or IMSI.These silent calls will map to TMSI and TMSI can be used to calculate frame number which further leaks Kc using Kraken and the GSM privacy will be exploited.
