Abstract: Smart-phones are becoming so popular these days because of their extra features and their extraordinary capabilities compared to regular phones. They are very similar to PCs and laptops; therefore they are vulnerable to security problems and even worse with respect to memory and space limitations. Since smartphones are connected to the internet so chances of security attacks are more to them along with GSM network Attacks. Lots of attractive games and applications are developed which intends to install suspicious software which can control our mobile phones by STK attacks. These applications can steal the secure information from our phone by STK attacks - send automatic SMS or make automatic calls.Smart-phones Vs simple mobile phones use different technologies, so they are more exposed to different attacks. In addition, they are interoperating devices which work between the Internet and telecom networks, so they can bring Internet security threats to the telecom networks and cause serious damages. In this thesis STK-SMS attacks against Smartphone’s are presented and some countermeasures against the attack are introduced. In addition, some solutions internet-side defense and telecom-side defense and coordination mechanism in order to make these threats ineffective are discussed.
