Abstract

The invention discloses an inter-android application attack-based automatic patching system and method. The method comprises a configuration initialization step, a path extraction step, a key point locating step and an inter-application attack patching step. According to the automatic patching system and method, the system runs in an application layer, upper-layer semanteme can be captured very accurately to identify a malicious behavior, and automatic patching is performed for the behavior; two-way control is used, relatively rich attack types can be identified, and relatively good analytic protection capability is achieved; a mode of combining static analysis with dynamic protection is adopted, so that the deficiency of a conventional method for the malicious behavior in an application is overcome; and a protective method for inter-application malicious attack is provided, so that a protective effect is comprehensive and effective.

Description

technical field

[0001] The invention belongs to the technical field of computer security protection, and in particular relates to an automatic patching method applied to an Android platform and a system for realizing the method. Background technique

[0002] In recent years, with the continuous improvement of the functions of smart phones, the penetration rate of smart phones is getting higher and higher. As an open source operating system, Android has already occupied 83% of the market share in 2015. Due to its absolute dominance and its open source nature, Android devices have also become the target of many malicious attackers. The imperfection of the Android platform or the unintentional exposure of the interface by the developer will lead to inter-application attacks. As a type of attack method on the Android platform, inter-application attacks have been used in many attack scenarios recently. However, there are currently no good defenses against such attacks, leaving...
