In this talk Bogdan Alecu shows how to make a phone send an SMS message without the user’s consent and how to make the phone not to receive any message. The method used works on any phone, no matter if it’s a smartphone or not and also on any GSM/UMTS network. Bogdan presents how you can take advantage of sending a special crafted SIM Toolkit command message in order to achieve all that. Finally, you will see the results and their impact on the user and mobile networks security.
This talk was held at DeepSec 2011 conference.
