The collection of infected systems called botnet which is controlled by the one named as bot master. Botnets are capable to initiate many DoS attacks. Denial of Service attack (DoS) is attempted by the attacker to prevent legal user and in Distributed Denial of Service attack (DDoS) the attacker sends more number of unwanted request at the same time to infect particular host. The botnet control...

The Internet of Things has become a cutting-edge technology that is continuously evolving in size, connectivity, and applicability. This ecosystem makes its presence felt every aspect our lives, along with all other emerging technologies. Unfortunately, despite the significant benefits brought by IoT, increased attack surface built upon it more critical than ever. Devices have limited resources...

Remote-controlled malware, organized in so-called botnets, have emerged as one of the most prolific kinds of malicious software. Although numbers vary, in extreme cases such as Conficker, Bredolab and Mariposa, one botnet can span up to several million infected computers. This way, attackers draw substantial revenue by monetizing their bot-infected computers. This thesis encapsulates research o...

Botnet is a network of compromised computers controlled by the attacker(s) from remote locations via Command and Control (C&C) channels. The botnets are one of the largest global threats to the Internet-based commercial and social world. The decentralized Peer-to-Peer (P2P) botnets have appeared in the recent past and are growing at a faster pace. These P2P botnets are continuously evolving fro...

Botnets are recognized as one of the most dangerous threats to the Internet infrastructure. They are used for malicious activities such as launching distributed denial of service attacks, sending spam, and leaking personal information. Existing botnet detection methods produce a number of good ideas, but they are far from complete yet, since most of them cannot detect botnets in an early stage ...

Botnets are now recognized as one of the most serious security threats. In contrast to previous malware, botnets have the characteristic of a command and control (C&C) channel. Botnets also often use existing common protocols, e.g., IRC, HTTP, and in protocol-conforming manners. This makes the detection of botnet C&C a challenging problem. In this paper, we propose an approach that uses network...
