I, recently started to work on Android features and analyzing some RAT (Remote Administration Tools) behaviors. I realized that Live Video Streaming is only supported for activity based on RATs. But I could stream the live video and audio without user notice.
Motivation
I’m working on a research based Android Malware and decided to create a multi function RAT (Remote Administration Tool). I was working on Live Streams which I’ve found some RTMP based open sources projects including:
From my GitHub: https://github.com/mirsamantajbakhsh/LiveHiddenCamera
https://github.com/begeekmyfriend/yasea
https://github.com/ant-media/LiveVideoBroadcaster
https://github.com/TakuSemba/RtmpPublisher
https://github.com/fyhertz/libstreaming which, all have some kind of problems based on the requirements of a RAT. But the common one was that they all need an activity to include aSurfaceView
.
Therefore, I’ve started searching. Finally, I could create Live Hidden Camera which only needs a CONTEXT for stream live video, by combining these two projects:
https://github.com/begeekmyfriend/yasea
https://github.com/kevalpatel2106/android-hidden-camera
The other motivation was that there was not (based on my search) any other library or code for stream live video and ausio. Source: https://github.com/wishihab/Android-RATList .
Therefore I decided to work on a Live Hidden Camera streamer for Android.
What Happens in Camera
Android only permits one application to access the camera hardware simultaneously. And only pass image data if the application (who opened camera) shows a preview to the user.
Bypassing the Preview
I’ve found a library in which bypass the camera preview by creating a fake surface (1*1) but the application has to have permission to alter (overlay) system display.
But problem still exists. I wanted to stream the live audio and video from android camera, and all the existed libraries (based on my search) were used SurfaceView such as:
- https://github.com/begeekmyfriend/yasea
- https://github.com/ant-media/LiveVideoBroadcaster
- https://github.com/TakuSemba/RtmpPublisher
- https://github.com/fyhertz/libstreaming
It Begins
I’ve decided to embed the idea from this library and tried to embed in this live rtmp streamer android application. After lots of effort, finally I could create the Live Hidden Camera library which streams live video and audio from android device without showing any preview to the user.
Download
The library is uploaded to bintray and the source code (+ released aar file) is available in my Live Hidden Camera repository in my GitHub.
There are some problems and TODOs in the project (https://github.com/mirsamantajbakhsh/LiveHiddenCamera#Problems) which you can check.
Any contribution is welcomed.
Happy streaming!
it seems like you know what are you doing im not a coder but i really like this cind of stuff a guy he buikd this for me http://www.andrologger.com and i would really want to know how your program works but i have no idea about his stuff how can i test your program?
Hi and thanks for your interest. I just merged two different ideas from two different libraries:
You can create a project in Android Studio and add the library. The details are in: https://github.com/mirsamantajbakhsh/LiveHiddenCamera
