초록
사람들과 소통하면서 동시에 프라이버시를 보호하기 위하여 일부 초대받은 사람들과 소통할 수 있는 SNS (Social Network Service) 서비스인 폐쇄형 SNS를 이용하는 사람들이 많다. 하지만 이를 악용하여 조직적으로 불법 촬영물을 유통, 공유하거나 마약을 유통 및 판매하는 등 악성 행위들이 발생하는 만큼 폐쇄형 SNS에 대한 디지털 포렌식은 더욱 중요해질 것이다. 해당 논문에서는 네이버 밴드에서 제공하는 기능을 간단히 소개하고 안드로이드 환경에서 네이버 밴드 어플리케이션을 통해 확보할 수 있는 의미 있는 데이터 및 로컬 아티팩트로 확인할 수 있는 악성 행위와 안티 포렌식 행위를 살펴보고, 요청 API (Application Programming Interface) 재구성을 이용해 로컬 아티팩트에서는 확인할 수 없는 정보를 수집하는 방안을 제시한다.
Abstract
Many people use closed SNS (social network service) that allows them to communicate with some invited people at the same time to protect their privacy. However, digital forensics for closed SNS will become more important as malicious acts such as distributing and sharing illegal filming or distributing and selling drugs systematically occur by exploiting this. In this paper, we briefly introduce the functions provided by Naver Band, look at meaningful data that can be obtained through Naver Band applications and anti-forensics behaviors that can be identified by local artifacts in Android environments, and suggest ways to collect information that cannot be found in local artifacts by using API(Application Programming Interface) reconstruction.
