Short for
Global Threat bot, a GTbot is a renamed
mIRC client (usually temp.
exe)
running in stealth mode. It uses the HideWindow program to enable it to run
stealth, and can contain any number of Mirc bot
scripts. This
Trojan is usually
downloaded by users on
IRC networks when they are tricked into thinking it is a
cleaner utility program. Once installed the Trojan launches the stealth mIRC and joins a
channel on an IRC network and awaits commands of the bot master.
These bots are one of the key instruments in launching DDOS attacks to users on
IRC.
