Botnets pose a major problem to Internet security. They can cause various online crimes such as DDoS attacks, identity thefts and spam e-mails. While there have been many attempts to detect botnets, most of these studies have difficulties in detecting botnets due to their evasive techniques to resemble normal traffic. In this paper, we propose a visualization method, BotXrayer, to detect botnet...

Cyber-criminals can distribute malware to control computers on a networked system and leverage these compromised computers to perform their malicious activities inside the network. Botnet-detection mechanisms, based on a detailed analysis of network traffic characteristics, provide a basis for defense against botnet attacks. We formulate the botnet defense problem as a zero-sum Stackelberg secu...

Botnets are now the key platform for many Internet attacks, such as spam, distributed denial-of-service (DDoS), identity theft, and phishing. Most of the current botnet detection approaches work only on specific botnet command and control (C&C) protocols (e.g., IRC) and structures (e.g., centralized), and can become ineffective as botnets change their C&C techniques. In this paper, we present a...

BotNet is a type of malware that has posed serious threats to Internet community and has been a common weapon for committing cybercrimes such as spam generation, stealing sensitive information, click fraud and DDOS attacks. In this document, we propose an approach for BotNet detection at large scale where network traffic is monitored at a central core in the Internet (say a Tier-1 ISP) so that ...
