Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] figure 1 For the flow chart of the method for injecting DLL files provided by the embodiment of the present invention, refer to figure 1 , the method can include:

[0029] Step S100, acquire the running status information of the target application program.

[0030] The target application program can be any application program installed on a user terminal device (such as a computer, a mobile phone, etc.) that needs to be run on a network, such as a gam...

Abstract

The invention provides a method and device for implanting a DLL file. The method comprises the steps that running state information of a target application program is obtained; whether a process of the target application program is started or not is judged according to the running state information of the target application program; when the running state information of the target application program shows that the process of the target application program is started, a mechanism responsible for network access operation of the target application program in an operation system is adopted for implanting the target DLL file into the process of the target application program, wherein the target DLL file meets the mechanism responsible for network access operation of the target application program in the operation system. The method and device for implanting the DLL file are free of the influence of the shelled application program or safety software, and high in implanting success rate.

Description

technical field [0001] The invention relates to the technical field of network communication, and more specifically, relates to a method and a device for injecting a DLL file. Background technique [0002] Injection (Inject) refers to placing a piece of third-party logic code into the application program memory and executing it. At present, most of the third-party logic codes commonly used in the industry are DLL (Dynamic Link Library, dynamic link library) files. It uses DLL injection technology. In the prior art, mainstream DLL injection technologies used by major security vendors mainly include registry injection DLL and remote thread injection DLL. [0003] However, at present, many application program clients will pack the executable programs after they are released, and many security software will be installed on the terminal devices where the application program clients are installed. In this case, the DLL injected into the registry or the DLL injected by the remote...
