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...

The research objective of this project is to investigate one possible advanced botnet – honeypotaware peer-to-peer (P2P) botnet: verifying our analysis of the propagation of a honeypot-aware P2P botnet, and then showing the feasibility of developing a such botnet in terms of its propagation effectiveness. A “botnet” is a network composed of compromised computers (“bots”) on the Internet, that a...

A botnet, which is a group of compromised and remotelycontrolled computers (also called bots), poses a serious threat to the Internet. The commonly-used command and control (C&C) channel for a botnet is used by a central server, such as IRC or HTTP. Recently, Storm botnet, a P2Pbased botnet with a decentralized C&C channel has appeared in the wild. In this paper, we propose a distributed approa...

Research on botnet mitigation has focused predominantly on methods to technically disrupt the commandand-control infrastructure. Much less is known about the effectiveness of large-scale efforts to clean up infected machines. We analyze longitudinal data from the sinkhole of Conficker, one the largest botnets ever seen, to assess the impact of what has been emerging as a best practice: national...

In this study, we advance the understanding of botmaster-owned systems in an advanced botnet, Waledac, through the analysis of file-system and network trace data from the upper-tiers in its architecture. The functionality and existence of these systems has to-date only been postulated as existing knowledge has generally been limited to behavioral observations from hosts infected by bot binaries...
