From the program's website:
This software allow you to make hundreds of functions stealthly and remotely without any kind of autorisation in the remote process.
Real administrators have had this functionality for years, it's called "ssh" with public key authentication. (There's absolutely no legitimate use for remote access with zero authentication.)
DarkComet is design with the latest IDE of Delphi
No one uses Delphi for writing serious software.
Works in chinese systems : The client is coded in a full natif Unicode environement then it can easily use and traduce in China, also since version 2.1 it works in all kind of Chinese operating system and display the correct Unicode characters.
Congratulations, welcome to the 21st century! Unicode has been supported by pretty much all mainstream operating systems for years. The fact that they have to mention it is indicative of poor software quality.
Oh yeah, and the UI looks like it was designed by a 10-year-old in Visual Basic 6.
tl;dr, this program isn't worth bothering with for *any* operating system for any use. It's just so poorly written that it'll probably break while being used.
