AI Technical Summary

Problems solved by technology

The rule-based vulnerability detection method needs to rely on manual expert experience to extract rules, which is labor-intensive and has a large number of false negatives
The learning-based Android application vulnerability detection method lacks research on the vulnerabilities caused by the operating mechanism of Android itself.
In other words, the efficiency and accuracy of the existing two vulnerability detection methods are low

Abstract

The present disclosure provides a vulnerability detection method for Android applications and related devices, including: constructing a control flow graph of the target Android application; building a program dependency graph of the target Android application based on the control flow graph; The vulnerability characteristics of the target Android application; use the vulnerability characteristics to train the pre-built machine learning model, obtain the vulnerability detection model, and detect the vulnerability of the target Android application based on the vulnerability detection model. The vulnerability detection method and related devices for Android applications provided by the present disclosure, according to the acquired vulnerability characteristics of Android applications with semantics, train a vulnerability detection model with context awareness, which can quickly and effectively detect vulnerabilities of Android applications .

Description

technical field [0001] The present disclosure relates to the technical field of information security, and in particular to a vulnerability detection method and a related device for Android application programs. Background technique [0002] In recent years, the number of Android applications has been growing rapidly, but with the increase there are also vulnerabilities generated by Android applications. As stated in the "Overview of my country's Internet Network Security Situation in 2020", the number of security vulnerabilities collected by the National Information Security Vulnerability Sharing Platform (CNVD) accounted for 8.0% of the total number of security vulnerabilities collected in the whole year. Compared with 2019, the year-on-year increase was 37.1% %. The vulnerabilities of all Android applications have the potential to be exploited by attackers. Therefore, a more comprehensive understanding of vulnerabilities, so as to discover vulnerabilities and fix them, is ...
