When I extract some file from the android application, I found tons of PNG files, however the png viewer cannot recognize the picture from what i have found.
When I check the HEX of the file, they have the following common code.
6F 70 6C 78 78 7A 64 30 37 66 38 6E 30 78 67 73
The following header is common for all sort of those PNG files.
Here are some of the example files.
Please guide if there is any encryption technique among those PNG files...
I had attempt to incorporate these png into typical framework, it showed the dimension but no images. Screen Capture
