Method and device for intercepting malicious advertisements of application program

[0020] figure 1 The flow of the method for blocking application malicious advertisements provided by the first embodiment of the present invention is shown, and only the parts related to the embodiment of the present invention are shown for convenience of description.

[0021] The method for blocking application malicious advertisements provided in this embodiment includes the following steps:

[0022] Step S101, scanning the application programs installed on the mobile terminal.

[0023] This step does not limit the specific time for scanning the application program. It can be to scan the application program while the application program is installed, or after being triggered by the user's button, start to uniformly scan each application program on the mobile terminal, preferably after the application program is installed. Program scanning is performed at the same time as the program.

[0024] Step S102 , judging whether there is malicious advertising platform code embedded in

[0029] figure 2 The flow of the method for blocking application malicious advertisements provided by the second embodiment of the present invention is shown, and only the parts related to the embodiment of the present invention are shown for convenience of description.

[0030] The method for blocking application malicious advertisements provided in this embodiment includes the following steps:

[0031] Step S201, updating the software development kit of the malicious advertisement platform in the malicious advertisement database.

[0032] The advertising content that the malicious advertising platform needs to push is not constant, so advertisers will upgrade and change the SDK content of the malicious advertising platform from time to time, and may also add new advertising platforms, so we need to provide a mechanism in the system , these malicious advertising platform SDKs can be dynamically collected and added, so in this step, the collected malicious advertising platform S

[0042] image 3 The structure of the application program malicious advertisement blocking device provided by the third embodiment of the present invention is shown, and only the parts related to the embodiment of the present invention are shown for the convenience of description.

[0043] The application malicious advertisement blocking device provided in this embodiment includes:

[0044] A program scanning unit 301, configured to scan the application programs installed on the mobile terminal;

[0045] Malicious code judging unit 302, configured to judge whether malicious advertising platform code is embedded in the application program;

[0046]The malicious advertisement isolation unit 303 is configured to isolate the malicious advertisement platform in the application program when the judgment of the malicious code judging unit is yes, so that the code of the malicious advertisement platform becomes invalid and cannot run.
