Embodiment Construction

[0045] Next, the technical scheme in the present application will be clear and completely, and the embodiments described herein are described herein, and not all of the embodiments of the present disclosure, not all of the embodiments of the present application. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative labor, are the scope of the present application.

[0046] There are still some problems with existing binary code clone vulnerability detection techniques, such as:

[0047] I. Pattern-based matching requires experts to define the cost of human labor costs, and typically produce a high false positive rate or leakage rate.

[0048] Second, code-based similarity detection can only detect code multiplex vulnerabilities, and for the case with different code structures, but there is a similar vulnerability triggering scene, it will lead to higher missing.

[0049] Third, due to the existence of the...

Abstract

The embodiment of the invention provides a vulnerability detection method and device, equipment and a storage medium, and relates to the technical field of network information security, and the method comprises the following steps: firstly, decompiling a binary code of a to-be-detected program into a pseudo code; detecting a dangerous function in a pseudo code, then taking the dangerous function as a slice point, extracting a slice code related to the calling of the dangerous function, then converting the slice code into vector representation, and finally taking the vectorized slice code as input, and judging whether a program to be detected contains vulnerabilities or not by detecting a neural network. The method can be used for cross-architecture and cross-platform binary code vulnerability recognition scenes, fine-grained detection of vulnerabilities is achieved on the binary code level, automatic feature extraction can be effectively achieved, the high false alarm influence caused by different compilation options and patch codes is relieved, and the method has extremely high accuracy and extremely low false alarm rate and missing report rate.

Description

Technical field [0001] In particular, in terms of network information security technology, in particular, there is a vulnerability detection method, apparatus, device, and storage medium. Background technique [0002] There are many current network attacks through vulnerability, so the vulnerability has found a important research direction in the security field. [0003] Since there is a large number of reused code libraries or shared code logics in the software system (for example, similar objects have similar processing logic in different purposes), there is a wide range of similar features in actual procedures but have not been discovered. Vulnerability. Also, many developers do not perform in-depth security analysis when reuse libraries to discover potential vulnerabilities in code. Therefore, repetitive vulnerability detection has been widely popular, especially with the increase in vulnerability. [0004] For existing binary code clone vulnerability detection, it is mainly ...
