스마트폰은 언제 어디서나 이용 가능한 소형 컴퓨터로 진화함으로써, 해커들의 주요 공격 타깃이 되고 있다. 해커는 스마트폰에 설치된 악성코드를 통해 개인정보를 탈취할 수 있을 뿐만 아니라, 휴대폰 소액 결제 및 프리미엄 SMS 서비스를 이용하여 금전적 이득을 취할 수 있다. 악성코드에 감염된 스마트폰으로부터 얻을 수 있는 이러한 이득과 함께 모바일 악성코드는 그 수가 급속히 증가하고 있다. 특히, 안드로이드 마켓의 개방성과 안드로이드 단말의 높은 시장 점유율은 악성코드의 유포를 용이하게 하며, 이러한 이유로 모바일 악성코드의 대부분은 안드로이드 단말을 공격 대상으로 삼고 있다. 본고에서는 이렇게 급속히 증가하고 있는 안드로이드 기반 모바일 악성코드의 특징을 살펴보고, 이들을 탐지하기 위하여 연구되고 있는 다양한 보안 기법들을 소개하고자 한다.
