Automated bot/botnet detection is a difficult problem given the high level of attacker power. We propose a systematic approach for evaluating the evadability of detection methods. An evasion tactic has two associated costs: implementation complexity and effect on botnet utility. An evasion tactic’s implementation complexity is based on the ease with which bot writers can incrementally modify cu...

Botnet continue to be a significant threat to Internet. Accordingly, the present research of botnet traffic detection mainly based on the assumption that communication or attack flows between a botnet tend to have space-time similarities. However, in order to bypass existing detection systems, attackers begin to add some randomness to the process of botnet propagation and control to make the fe...

Botnet phenomenon in smartphones is evolving with the proliferation in mobile phone technologies after leaving imperative impact on personal computers. It refers to the network of computers, laptops, mobile devices or tablets which is remotely controlled by the cybercriminals to initiate various distributed coordinated attacks including spam emails, ad-click fraud, Bitcoin mining, Distributed D...

As a lot of sophisticated duties are being migrated to mobile phones, they are gradually becoming hot targets of hackers. Actually, during the past few years, It has appeared many malware targeting mobile phones and the situation is getting worse. Under this circumstance, we may ask a serious question: whether can those infected phones be organized to a botnet? In this paper, we present a desig...

As evidenced by the recent botnet turf war between SpyEye and Zeus, the cyber space has been witnessing an increasing number of battles or wars involving botnets among different groups, organizations, or even countries. One important aspect of a cyber war is accurately estimating the attack capacity of the enemy. Particularly, each party in a botnet war would be interested in knowing how many c...

The results of botnet detection methods are usually presented without any comparison. Although it is generally accepted that more comparisons with third-party methods may help to improve the area, few papers could do it. Among the factors that prevent a comparison are the difficulties to share a dataset, the lack of a good dataset, the absence of a proper description of the methods and the lack...

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 ...

this paper presents the results obtained from the life cycle assessment (lca) of the productionof sicilian artichokes (cynara scolymus) with the aim of reducing impacts, interpreting the results, suggesting possible improvements and enriching the sustainability knowledge already existing in the agro food field. artichokes represent one of the excellent italian agricultural products even if stil...
