Since the number of compromised computers, or botnet, continues to grow, the cyber security problem has become increasingly important and challenging to both academic researchers and industry practitioners. A respect to combat botnet propagation is to understand the attacker’s behaviors based on the whole operation of a system that can be modeled with population models used in epidemiological s...

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...

With the increasing importance of Internet in everyone’s daily life, Internet security poses a serious problem. Now-a-days, botnets are the major tool to launch Internet-scale attacks. A “botnet” is a network of compromised machines that is remotely controlled by an attacker. In contrast of the earlier hacking activities (mainly used to show off the attackers’ technique skills), botnets are bet...

Email has become an integral part of everyday life. Without a second thought we receive bills, bank statements, and sales promotions all to our inbox. Each email has hidden features that can be extracted. In this paper, we present a new mechanism to characterize an email without using content or context called Email Shape Analysis. We explore the applications of the email shape by carrying out ...

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...

The cyber world provides an anonymous environment for criminals to conduct malicious activities such as spamming, sending ransom e-mails, and spreading botnet malware. Often, these activities involve textual communication between a criminal and a victim, or between criminals themselves. The forensic analysis of online textual documents for addressing the anonymity problem called authorship anal...
