What Does Global Threat Bot Mean?
The global threat bot, commonly known as GTbot, is an IRC bot and backdoor trojan. The GTbot is mIRC-based and spreads when a user is tricked into downloading what appears to be a software utility (such as a disk cleaner).
GTbot is also known as Aristotles or IRC Trojan Aristotles.
Techopedia Explains Global Threat Bot
After a computer is infected with GTbot, the trojan runs a stealth mIRC client without the user’s knowledge. The attacker can then gain information about the infected computer, as well as use the infected computer to launch a denial-of-service (DoS) attack.
Popular files names for GTbot are as follows: temp.exe, miri.inc, script.inl, temp.scr and WHVLXD.DAT.
