在你逆向分析**app时,分析分析其数据存储结构绝对是事倍功倍.

下面是我在hook 微信sqlite暗码的分享

知识准备

1：懂的利用xposed框架或Cydia框架hook技术

2 ：jadx工具(定位分析工具)

static public void wechatOpenDatabase(String wechatVersionName, final XC_LoadPackage.LoadPackageParam lpparam) {

/**

*调用生成SQLiteDatabase 重要入口

* //主要第3个参数是sqlite的暗码

public static SQLiteDatabase openDatabase(String paramString1, LockedDevice paramLockedDevice, String paramString2, Arithmetic paramArithmetic, CursorFactory paramCursorFactory, int paramInt1, DatabaseErrorHandler paramDatabaseErrorHandler, boolean paramBoolean, int paramInt2)

{

SQLiteDatabase localSQLiteDatabase = new SQLiteDatabase(paramString1, paramInt1, paramCursorFactory, paramDatabaseErrorHandler);

localSQLiteDatabase.open(paramLockedDevice, paramString2, paramArithmetic, paramBoolean, paramInt2);

return localSQLiteDatabase;

}

try {

if (wechatVersionName.equals("6.3.13.56_r238e8af")){

clazzPalue3 = String.class;

}else {

clazzPalue3 = byte[].class;

}

XposedHelpers.findAndHookMethod(PluginsConfigWechatSqlite.WECHAT_SQLiteDatabase_CLASSE, lpparam.classLoader, "openDatabase",

System.out.println("SQLiteDatabaseObject的类名:"+ EnMicroMsgSQLiteDatabaseObject.getClass().getName());

}

}

@Override

protected void beforeHookedMethod(MethodHookParam param) throws Throwable {

//SQLiteDatabase db = SQLiteDatabase openDatabase(String path, SQLiteDatabase.CursorFactory factory, int flags)

String mm ="";

if (param.args[2] !=null){

String str= param.args[2].getClass().getName();

if (str.equals("[B")){

byte[] mmbytes = (byte[]) param.args[2];

mm = new String(mmbytes,"UTF-8");

}else if (str.equals("java.lang.String")) {

mm =""+param.args[2];

}

}

//Log.i(TAG,"openDatabase String 0参数sqlite全路径和暗码： " +param.args[0]+"参数sqlite暗码：" +param.args[2].toString());

Log.i(TAG,"openDatabase String 0参数sqlite全路径和暗码： " +param.args[0]+"参数sqlite暗码：" +mm);

}

});

} catch (ClassNotFoundException e) {

e.printStackTrace();

}

}

jadx工具分析定位在com.tencent.mmdb.database.SQLiteDatabase

启动**发现微信启动时同时打开的数据库有
