SIGNAL.EXE REVERSE / DECOMPILATION

Image
Hello everyone! Recently i have got installed signal and u have probably know it as a secure messaging app.  As any software which comin to my pc i has tried to decompile it and the final result is different. Firstly, i have tried to analyze it but the obfuscation level is heavy, so the result is incomplete. Despite analysis failure i still have some data in strings, probably names of functions. And the functions strange. We can see somthin named screenshot, prob a function which making a screenshot, but the secure messaging app shouldn't acquire such functionality doesn't it? Next is somthin related to debugger is ok, but signal strength and mac address definitely doesn't. Also i got something related to virtualbox VM detection. As a quick report i unable to advise this messenger to use, in my own software i never use something similliar to this, but i have only protection from debugger.
