Welcome to!

Botnets are a network of computers which interconnect after they have been infected with a malicious payload. If a computer is part of a botnetwork, then it will go unnoticed by its owner that remote commands were sent by cyber criminals to be used for distributing Spam or infecting other computers whilst being online.

Botnets function as an infrastructural basis of Internet crime, and are one of the largest illegal sources of income in the Internet. With the Anti-Botnet-Advisory Centre we would like to reduce the number of Botnet infected computers and so withdrawing a cyber criminals foundation.
