We just released a new paper on iPhone Malware paradigm in CrossTalk Journal.
Abstract:The sphere of malware attacks is expanding to engulf the compact world of smartphones. This paper sheds light on exploitation tactics used by malware writers in designing iPhone applications that exploit the integrity of the victim’s phone. Our interest is in the harder problem of malware on iPhones that are not jailbroken.
