Abstract

A malicious code positioning device of an Android repackaging application comprises a position determining unit suitable for determining the position of a sensitive API in the Android repackaging application when it is determined that the preset sensitive API is called in the Android repackaging application; a code determining unit suitable for determining suspicious codes existing in the Androidrepackaging application based on the determined position of the sensitive API in the Android repackaging application and a calling path of the sensitive API determined in the Android repackaging application; and a detection unit suitable for independently executing the determined suspicious codes so as to detect whether the suspicious codes are malicious codes or not. According to the scheme, themalicious code existing in the Android repackaging application can be accurately determined.

Description

technical field [0001] The invention relates to the technical field of computer security, in particular to a device for locating malicious codes of Android repackaged applications. Background technique [0002] Mobile Internet combines mobile communication and the Internet into one, and is a general term for activities that combine and practice Internet technologies, platforms, business models and applications with mobile communication technologies. In recent years, with the continuous development of Internet technology and the reduction of manufacturing costs, mobile terminal devices represented by smart phones have gradually penetrated into people's lives. [0003] While mobile Internet technology brings us convenience, it also brings various hidden dangers. Especially after the launch of the Android operating system, with its openness and ease of development, it quickly occupied half of the mobile operating system, but this also made it a target for malicious program att...
