Botnet is most widespread and occurs commonly in today‘s cyber attacks, resulting in serious threats to our network assets and organization’s properties. Botnets are collections of compromised computers (Bots) which are remotely controlled by its originator (BotMaster) under a common Command-andControl (C&C) infrastructure. They are used to distribute commands to the Bots for malicious activiti...

Bitcoin, a decentralized P2P currency in recent years has gained a tremendous attention due to its ability to create anonymous financial transactions. This leads to bitcoins being the choice of currency for users having privacy as a important issue. Bitcoin mining, a process resulting in the generation of new bitcoins, is performed by miner operators for reception of incentives in the form of B...

Botnets like Kelihos.B consist of infected computers that are used for malicious purposes. A large part of the Kelihos.B botnet was sinkholed and the bots in it send all their requests to controlled servers. All those requests are then stored in log files on the servers. These log files are used in this paper to find characteristics about this Kelihos.B botnet. Two types of analyses were conduc...

Botnet have already made a big impact that need much attention as one of the most emergent threats to the Internet security. More worst when the peer-to-peer (P2P) botnets take the inspiration and underlying P2P technology to exchange files making botnets much harder to detect and shut down. It make botnets are the biggest threat to internet stability and security. Hence, Botnet detection and p...

An automatic Botnet detection and notification system is developed by National Center for High-Performance Computing (NCHC) in Taiwan to efficiently inform users of malware infections on their computers. Due to the involvement with manual work in current notification flow, the notification time may last for 48 to 60 hours. By the aid of our notification system, the infected bot can be notified ...

Botnet ia a collection on network of bots. i.e the collection of zombie computers which are controlled by a single person or group known as bot master or herder. This paper focuses on botnet detection framework and proposed a generic framework for botnet detection. The proposed framework is based on the approach of passively monitoring network traffic. This paer also show the flow chart of Gene...

This paper provides a detailed case study of the architecture of the Clickbot.A botnet that attempted a low-noise click fraud attack against syndicated search engines. The botnet of over 100,000 machines was controlled using a HTTP-based botmaster. Google identified all clicks on its ads exhibiting Clickbot.Alike patterns and marked them as invalid. We disclose the results of our investigation ...

This paper aims to understand empirically the impact of a largescale spamming botnet, and the effectiveness of targeting its core infrastructure – C&C servers – from the viewpoint of several Internet edge sites. We also attempt to study the characteristics of the spamming botnet in the long-term to see how quickly bot masters react and what type of action they take. Our primary target in this p...

Botnets have continuously evolved since they were first created. This evolution is now being fueled by a talent influx generated by the incentive of the monetary gains facilitated by botnet operations. This talent base has allowed new botnet generations to continuously side-step mitigation techniques. This is also due to the fact that computer security has generally reacted to new malware as it...

A botnet is a network of compromised hosts controlled by a single entity, called the botmaster. These compromised hosts can be utilized for malicious activities such as Distributed Denial of Service (DDoS) attacks, SPAM, and information extraction such as the extraction of user authentication via key-logging each of which nets profits to the botmaster. Research in the detection of botnets is ex...
