But the inventor finds that the Windows system kernel layer also provides the NtUserSetSysColors function corresponding to the SetSysColors function. If a malicious program calls the NtUserSetSysColors function, because this method is relatively hidden, the current security defense software has not yet taken protective measures for this malicious call. In this way, malicious software can modify the system color and damage the system environment

Abstract

The embodiment of the invention discloses a method and a device for preventing system colors from being maliciously modified and electronic equipment and relates to the technical field of computer safety, aiming at effectively preventing the system colors from being modified by malicious programs and improving the safety performance of a system. The method comprises: monitoring an event which is called for modifying system color functions in an operating system by a process; according to the monitored event, obtaining a process path of the process; according to the process path, judging whether the process is a malicious program process or not; if so, rejecting to modify the system colors by the process. The method and the device, disclosed by the invention, are suitable for preventing the system colors from being modified by the malicious programs and the safety performance of the system is improved.

Description

technical field [0001] The invention relates to the technical field of computer security, in particular to a method, device and electronic equipment for preventing system colors from being maliciously modified. Background technique [0002] In the Window system, the SetSysColors function is provided to modify the system colors, including modifying the colors of the system's background, desktop, and windows. Therefore, malicious software can modify the system color by calling this function, such as changing the color of all objects in the system to transparent or black, so that the user cannot see the window or interface displayed by the system or cannot distinguish the displayed content. [0003] At present, in order to protect the system color from being modified maliciously, the usual method is to hook the SetSysColors function of the application layer. In this way, the hook function will monitor the event of calling the SetSysColors function, so as to know that the malici...
