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...

Botnets, i.e., networks of compromised machines under a common control infrastructure, are commonly controlled by an attacker with the help of a central server: all compromised machines connect to the central server and wait for commands. However, the first botnets that use peer-to-peer (P2P) networks for remote control of the compromised machines appeared in the wild recently. In this paper, w...

Unlike other types of malware, botnets are characterized by their command and control (C&C) channels, through which a central authority, the botmaster, may use the infected computer to carry out malicious activities. Given the damage botnets are capable of causing, detection and mitigation of botnet threats are imperative. In this paper, we present a host-based method for detecting and differen...

Botnets are security threat now days, since they tend to perform serious internet attacks in vast area through the compromised group of infected machines. The presence of command and control mechanism in botnet structure makes them stronger than traditional attacks. Over course of the time botnet developer have switched to more advanced mechanism to evade each of which new detection methods and...

The usefulness ofemail has been tempered by its role in the widespread distribution ofspam and malicious content. Security solutions have .focused on filtering out malicious payloads and weblinksfrom email; the potential dangers of email go past these boundaries: harmless-looking emails can carry dangerous, hidden botnet content. In this paper, we evaluate the suitability ofemail communicationf...

Black hat search engine optimization (SEO) campaigns attract and monetize traffic using abusive schemes. Using a combination of Web site compromise, keyword stuffing and cloaking, a SEO botnet operator can manipulate search engine rankings for key search terms, ultimately directing users to sites promoting some kind of scam (e.g., fake antivirus). In this paper, we infiltrate an influential SEO...

They are continuously developing with regard to protocols, structure and quality of attacks. Many botnet detection programs ...

It’s increasingly difficult to detect botnets since the introduction of P2P communication. The flow characteristics and behaviors can be easily hidden if an attacker exploits the common P2P applications’ protocol to build the network and communicate. In this paper, we analyze two potential command and control mechanisms for Parasite P2P Botnet, we then identify the quasi periodical pattern of t...

The botnet is a group of hijacked computers, which are employed under command and control mechanism administered by a botmaster. Botnet evolved from IRC based centralized botnet to employing common protocols such as HTTP with decentralized architectures and then peer-to-peer designs. As Botnets have become more sophisticated, the need for advanced techniques and research against botnets has gro...

As technology has been developed rapidly, botnet threats to the global cyber community are also increasing. And the botnet detection has recently become a major research topic in the field of network security. Most of the current detection approaches work only on the evidence from single information source, which can not hold all the traces of botnet and hardly achieve high accuracy. In this pa...
