Botnets are one of the most serious threats to internet security. A botnet is a network of computers on internet which are under the influence of a malware code, oblivious to the owner of that computer and sends out transmissions (virus or spam) to other computers on internet. Botnet can be utilized for DoS attacks, phishing, spamming and many other fraudulent activities. Therefore, it is impor...

A “botnet” is a network of compromised computers (bots) that are controlled by an attacker (botmasters). Botnets are one of the most serious threats to today’s Internet; they are the root cause of many current Internet attacks, such as email spam, distributed denial of service (DDoS) attacks , click fraud, etc. There have been many researches on how to detect, monitor, and defend against botnet...

The botnet is controlled by an attacker, which is formed by a lot of vulnerable hosts. The botnet is one of the biggest threats on the Internet. The attacker usually uses it to attack, such as: spam, distributed denial of service attacks, fraud and so on. In this paper, we mainly study the control channel of the botnet, including the IRC protocol, the P2P protocol and the HTTP protocol. At the ...

Botnets, overlay networks built by cyber criminals from numerous compromised network-accessible devices, have become a pressing security concern in the Internet world. Availability of accurate mathematical models of population size evolution enables security experts to plan ahead and deploy adequate resources when responding to a growing threat of an emerging botnet. In this paper, we introduce...

With the raise in practice of Internet, in social, personal, commercial and other aspects of life, the cybercrime is as well escalating at an alarming rate. Such usage of Internet in diversified areas also augmented the illegal activities, which in turn, bids many network attacks and threats. Network forensics is used to detect the network attacks. This can be viewed as the extension of network...

Botnets are considered one of the most dangerous and serious security threats facing the networks and the Internet. Comparing with the other security threats, botnet members have the ability to be directed and controlled via C&C messages from the botmaster over common protocols such as IRC and HTTP, or even over covert and unknown applications. As for IRC botnets, general security instances lik...

Botnets have evolved to become one of the most serious threats to the Internet and there is substantial research on both botnets and botnet detection techniques. This survey reviewed the history of botnets and botnet detection techniques. The survey showed traditional botnet detection techniques rely on passive techniques, primarily honeypots, and that honeypots are not effective at detecting p...

The recent evolution of Internet to new paradigms such as network function virtualization and software defined networking poses new relevant challenges to the detection of Botnet attacks, calling for innovative approaches. In this work we propose a detection mechanism based on an Artificial Neural Net classifier trained by available data sets collected in conventional networks. We apply such de...

A botnet is a network of compromised computers, termed bots that are used for malicious purposes. When a computer becomes compromised typically through a drive-by download, that has embedded malicious software, that computer becomes a part of a botnet. A bot typically runs hidden and uses a covert channel to communicate with its command and control server. Botnets are controlled through protoco...

A recent emerging trend in the underground economy is malware dissemination as a service. Complex botnet infrastructures are developed to spread and install malware for third-party customers. In this research work, a botnet forensic investigation model is proposed to investigate and analyze large-scale botnets. The proposed investigation model is applied to a real-world law-enforcement investig...
