Abstract

The invention discloses an anti-debugging method based on a signal processing mechanism. The anti-debugging method and device are used for solving the problem that in the prior art, application program attackers can use a debugger for attacking and breaking a targeted application program. The debugging method includes the steps that a monitoring process is created through a host process of the application program; a state signal is captured through the monitoring process, wherein the state signal includes the process state of the main process; if it is determined that the process state included in the state signal is a preset state, the host process is terminated, wherein the preset state is a state that an application program is debugged or attempted to debug through an external process. The invention further discloses the anti-debugging device based on the signal processing mechanism.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to an anti-debugging method and device based on a signal processing mechanism. Background technique [0002] With the rapid development of the mobile Internet industry, mobile applications are exploding, and more and more Android applications are developed based on the Android system. For the convenience of description, Android applications are referred to as applications in the following. [0003] Due to the open source nature of the Android system itself, applications are very vulnerable to Trojan attacks and piracy, and applications are gradually replacing computer-side programs as the main target of hacker attacks. [0004] In the prior art, an application attacker can use a debugger to track the running of the application, view and modify the memory code and data of the application, and analyze the program logic of the target application, thereby attacking and crack...
