Dark Comet RAT - Quote :
- control a computer from anywhere in the world
this is a RAT (remote administration tool) this allows you to run basic commands on another computer
the commands can be almost anything; keylogging, download/upload files from infected computers, use computers to DDoS.
Warning by law you may only use this on your computer or on a computer in witch the user has given consent to the use of this tool
please only download this if you know what you are doing, RATs can be very dangerous if not used correctly.
if you do not know much about RATs please look up more information on viruses, Trojans, and RATs.
the next thing stronger and far more complicated than a RAT would be a "BOT.NET"
Download Note: this will show up as a virus because it makes RATs, in its simple explanation can be considered a Virus (more specifically Trojan/dropper).
