Problems solved by technology

Since the executable file with the virus is downloaded after the application program is installed, and the application program does not carry the executable file before installation, the above-mentioned security detection method cannot identify whether these application programs are based on the file feature information. Applications with security risks

Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] First, some terms involved in the embodiments of the present invention are explained.

[0028] Hot patch technology: also known as plug-in technology, applications include host APP and patch APP, both of which are executable files. When the application program is released, the installation package of the application program may only include the host APP. After the application is installed, the host APP has the ability to download any specified patch APP from the server to install and run without the consent of the user. The developer of the application program can dynamically increase or modify the function of the application program through the hot patch technology.

[0029] Hot repair technology: The application program incl...

Abstract

The invention discloses an application security detection method and device, belonging to the field of information security. The method comprises the steps of acquiring an executable file in an application, wherein the application comprises at least one executable file; detecting whether the executable file uses a predetermined application programming interface (API), wherein the API is an API used for dynamically loading the executable file in running of the application; and if the executable file uses the predetermined API, determining the application as an application with a security risk.Through adoption of the application security detection method and device, a problem in the prior art that security risks of some applications cannot be identified through file characteristic information is solved; and when an application is an application supporting a hot patch technology or a hot fix technology, the application is determined as an application with a security risk, so that a usercan be warned of installing the application selectively.

Description

technical field [0001] The embodiments of the present invention relate to the field of information security, and in particular to a method and device for detecting the security of an application program. Background technique [0002] In a terminal running an operating system, various applications (English: Application) can be installed to achieve different functions. function. But with the development of technology, there are more and more malicious applications with viruses. [0003] The prior art provides a method for detecting the security of an application program, including: computer extraction of file feature information of the application program, such as file name or message digest algorithm fifth edition (English: Message Digest Algorithm, abbreviated: MD5); Whether the file feature information of the application program matches the virus feature information in the virus database; if the feature information of the application program matches the virus feature info...
