Go to part 2<\/a><\/p>\n

Since the investigation until now has not given any concrete hints as to how to achieve the main goals:<\/p>\n

    \n
  1. Make the socket associate and connect to my own Wifi network<\/li>\n
  2. Make the socket turn on and off<\/li>\n<\/ol>\n

    another approach was needed.<\/p>\n

    The next most obvious option to me, was to try to intercept the network-communication between the Maginon SP-2 app and a WIFI network. To do this, the app has to believe that it is connecting to a real socket. So I set a router up to imitate the Maginon socket – with the same SSID and WPA password that the socket uses. The router did not allow for modifying its MAC-address.<\/p>\n

    Sadly, although I, a few brief times, was able to see my “fake” WIFI from the app, I was never able to make the app believe it was the real socket enough to make it try to associate with it. This was a bommer, since I have read about several other sockets, where this was trivially easy. I still do not know why the app did not believe it was a real sockets WIFI.<\/p>\n

    Next option – decompile the Android app and look for hints. There are several free sites which will decompile an APK file.<\/p>\n

    With the Maginon app decompiled, you can search for a lot of interesting things in the .java files (eg. using ‘find’ in Linux or something like WinGrep on Windows)<\/p>\n
