Embodiment Construction

[0014] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the examples.

[0015] A method for accurately extracting Android WeChat Moments data, the steps are as follows:

[0016] S1. Read the Android WeChat Moments database

[0017] (1) The Android WeChat Moments database is stored in the directory / data / com.tencent.mm / MicroMsg in the user data partition of the Android system. The data of each WeChat account is stored in a folder with an MD5 coded character name consisting of 32 characters. By recursively recursing the folder with a 32-character coded character name in the MicriMsg directory, you can determine the historically logged in mobile phone. The number of WeChat accounts and the data storage path of each WeChat account. (2), read the SnsMicroMsg.db file data through the SQLite library, and judge whether there is a SnsInfo data table. If i...

Abstract

The invention discloses a method for accurately detecting data of an Android WeChat friend circle and belongs to the technical field of information security.The method comprises the steps of reading a database of the Android WeChat friend circle, including the operation of reading a SnsMicroMsg.db database, reading content of a SnsInfo data sheet, obtaining transmission time of a log and obtaining the name of a user sending the log; obtaining basic information of the log of Android WeChat friend circle, including the operation of conducting recursion on the data folder path of the WeChat user and reading the SnsMicroMsg.db database; obtaining the content and number of the log in the Android WeChat friend circle, including the operation of obtaining the internal number of a Wechat account sending the log, obtaining content data of the log, obtaining a connection title of the log and obtaining a connection address of the log.The method has the advantages that by means of the method, the historical data record of the friend circle in an Android Wechat application can be accurately extracted and used for data obtaining and analysis.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method for accurately extracting data from Android WeChat Moments. Background technique [0002] Due to the large increase in users of WeChat applications, user data generated in mobile WeChat applications has become the focus of mobile phone data forensics. In addition to user contact records and chat records, WeChat applications also contain a large number of user log information, that is, WeChat. circle of friends data. The data of WeChat Moments records the mood, photos, videos and other data released by users and their friends. It is particularly important to extract and analyze the data in WeChat Moments in the process of data forensics. However, in the Android WeChat application, the circle of friends data is stored in a data structure developed by Tencent itself, and it must be parsed in order to obtain it accurately. [0003] To sum up, it is particularl...
