Introduction:
A botnet is basically the collection of the devices that are connected by Internet that
can include servers, PCs, internet of things and mobile devices which are controlled and
infected though a common malware. The users can even unaware of the botnets infecting the
systems of them. The devices that are infected can be remotely controlled by cyber-criminals
and threat actors for some of the specific functions so that the malicious based operations will
be stay hidden for the users [1]. The botnets can be used commonly for sending spam emails,
engaging in clicking the fraud campaigning as well as generating malicious traffic for the
DDoS attack. The botnets impose social and economic costs on the users, network operators,
service providers as well as society as a whole. Without the having effective efforts for
mitigating them the botnets are having the potential to harm social and economic benefits of
Internet. The purpose of this paper is to discuss botnet technology, its effect, architecture and
at last the paper will provide a conclusion on the basis of entire report.
Variations of Botnet:
The botnets can be classified mainly into four type on the basis of C&C channels that
are used. They are:
i. IRC (Internet Relay Chat) botnet
ii. P2P (Peer to Peer) botnet
iii. HTTP (Hyper Text Transfer protocol) botnet
iv. Hybrid botnet.
IRC botnet:
The IRC Botnet is called as the push style model as the commands that are sent to the
botnets that are connected to the IRC channels from the botmaster. On the basis of the
