...Abstract—Nowadays, Botnets pose a major threat to the security of online ecosystems and computing assets. A Botnet is a network of computers which are compromised under the influence of Bot (malware) code. This paper clarifies Botnet phenomenon and discusses Botnet mechanism, Botnet architecture and Botnet detection techniques. Botnet detection techniques can be categorized into six classes: honey pot based, signature-based, mining-based, anomaly-based, DNS-based and network-based. It provides a brief comparison of the above mentioned Botnet detection techniques. Finally, we discuss the importance of honeypot research to detect the infection vector and dealing with new Botnet approaches in the near future. Keywords- Botnet; Bot; Malware; Malicious code; P2P; Honeypot functions programmed by the Bot-master in automated way. Bots can receive commands from the Bot-master and work according to those commands to perform many cyber crimes for example phishing [26], malware dissemination, Distributed Denial of Service attack (DDoS) attack, identity theft etc. The process of Botnet can be broadly divided into three parts: (1) Searching: searching for vulnerable and unprotected computers. (2) Distributing: the Bot code is distributed to the computers (targets), so the targets become Bots. (3) Sign-on: the Bots connect to Botmaster and become ready to receive command and control traffic...

...Botnets are computer programs that are designed to take control of your computer without your knowledge. They are designed to infect computers and allow hackers to remotely control your computer via an Internet connection. Most users are unaware their computer has been hijacked because little evidence can be found that the computer is not working as expected. Once a computer has been compromised it is sometimes referred to as a bot or zombie. Having antivirus or other security software on your computer can help reduce the risk of being compromised by botnets but hackers are constantly developing new ways to circumvent these measures. Updating antivirus software regularly is one way to minimize the likelihood that computers can be used for malicious purposes (“What are Bots, Botnets and Zombies?” n.d.). The impact of botnets on business functions can be profound. Not only can computers be made to perform tasks without the users awareness but software like GameOver Zeus, or GOZ, can be used to steal financial or any other type of data from consumers or businesses. Business owners should be very concerned about programs like GOZ because they have sophisticated techniques to compromise other computers on a network, therefore an entire corporate network could be compromised if just one computer were to become infected with GOZ. Also, businesses should be concerned about botnets because they can be used to perform distributed-denial-of-service (DDoS) attacks using hundreds of thousands...

... Internet bots, also known as web robots, WWW robots or simply bots, are software applications that run automated tasks over the Internet. Typically, bots perform tasks that are both simple and structurally repetitive, at a much higher rate than would be possible for a human alone. The largest use of bots is in web spidering, in which an automated script fetches, analyzes and files information from web servers at many times the speed of a human. Each server can have a file called robots.txt, containing rules for the spidering of that server that the bot is supposed to obey. In addition to their uses outlined above, bots may also be implemented where a response speed faster than that of humans is required for example, gaming bots and auction-site robots or less commonly in situations where the emulation of human activity is required, for example chat bots. Recently bots have been used for search advertising, such as Google AdSense. (Juusi, 2012) Internet bots are also commonly used in games such as RuneScape, despite the fact that it's not allowed. RuneScape has now known bots as illegal and you will receive a fine of $500-$2,500. Another, more malicious use of bots is the coordination and operation of an automated attack on networked computers, such as a denial-of-service attack by a botnet. Internet bots can also be used to commit click fraud and more recently have seen usage around MMORPG games as computer game bots. A spambot is an internet bot that attempts to...

...CAPTCHA CAPTCHAs (completely automated public Test to tell computers and humans apart) are in common use today as a method for performing automated human verification online. The most popular type of CAPTCHA is the text recognition variety. However, many of the existing printed text CAPTCHAs have been broken by web-bots and are hence vulnerable to attack. We present an approach to use human-like handwriting for designing CAPTCHAs. A synthetic handwriting generation method is presented, where the generated textlines need to be as close as possible to human handwriting without being writer-specific. Such handwritten CAPTCHAs exploit the differential in handwriting reading proficiency between humans and machines. Test results show that when the generated textlines are further obfuscated with a set of deformations, machine recognition rates decrease considerably, compared to prior work, while human recognition rates remain the same. CAPTCHA is now almost a standard security technology. The most widely used CAPTCHAs rely on the sophisticated distortion of text images rendering them unrecognisableto the state of the art of pattern recognition techniques and these text-based schemes have found widespread applications in commercial websites. The state of the art of CAPTCHA design suggests that such text-based schemes should rely on segmentation resistance to provide security guarantee, as individual character recognition after segmentation can be solved with a high...

...DCIT 65 - Web Development Botnet Edrilyn R. Fortuno BS IT 3 - 1 February 7, 2013 Botnet A botnet is a collection of computers that connected to the internet that interact to accomplish some distributed task. A bot is a type of malware that enables a network attacker to gain control over a computer and utilize it to launch third party attacks on the Internet. Software agents, or robots, that run autonomously and automatically. A group of computers running a computer application controlled and manipulated only by the owner or the software source. In the past, the concept of bots did not include harmful behavior by default.Bots can be very bene cial programs when they are designed to assist a human user, either by automating a simple task, or by simplifying a user's control over various programs or systems. Botnets are used for malicious activity like distributed denial of service attacks, identity theft, sending spams and phishing attacks. Typically botnets used for illegal purposes. Botnets are seen to be one of the main sources of malicious activity. Rapidly growing botnets and new methods for spreading malicious codes and launching attacks. Bots sneak into a persons computer in many ways. Bots often spread themselves across the Internet by searching for vulnerable, unprotected computers to infect. When they nd an exposed computer, they quickly infect the machine and then report back to their master. Their goal is then to stay hidden until they are instructed to carry...

I would like to thank my supervisor Dr Hatem Ahriz for his guidance throughout the writing of this report. I would like to thank Richboy and Ete Akumagba for their guidance and for proof reading this report. I would like to thank my family for their support and love. ii Abstract This era of explosive usage of networks have seen the rise of several opportunities and possibilities in the IT sector. Unfortunately, cybercrime is also on the rise with several forms of attack including, but not limited to botnet attacks. A Botnet can simply be seen as a network of compromised set of systems that can be controlled by an attacker. These systems are able to take malicious actions as needed by the attacker without the consent of the device owner and can cause havoc. This paper is the first part of a two-part report and discusses on several reportedly known botnets and describes how they work and their mode of infection. Several historic attacks and the reported damage have been given to give a good picture and raise the bar on the capabilities of botnets. Several existing tools have been considered and examined which are useful for detecting and terminating botnets. You would find that each tool has its own detection strategy, which may have an advantage on some end than others. iii Table of Contents Declaration ................

...Botnet’s The term bot is short for robot. Criminals distribute dangerous software known as malware that can turn your computer into a bot, also known as a zombie. When this happens your computer can perform automated tasks over the internet without you knowing it Criminals use bots to infect large numbers of computers. These infected computers form a network or a botnet. Which is a large number of infected computers Criminals use botnets to send out spam email messages, spread viruses, attack computers and servers, and commit other kinds of crime and fraud. Botnet is a good reason to have a very good viruses protection on your computer.

...Nowadays it seems like every chef or restaurateur is selling burgers. Bobby Flay has Bobby's Burger Palace; Danny Meyer has his uber-popular Shake Shack. Gabrielle Hamilton at Prune throws a little ground lamb into her burger to make it gamier. And that's not to mention all the chain burger joints creeping up around the country, from Umami Burger out west to Five Guys out east. The first and most obvious answer to the question of why we're so obsessed with burgers is: burgers are cheap. If you're going out to dinner and the entrees cost $33, the burger almost always costs half. It fills you up just as much as the filet of trout would (if not more) and it almost always comes with a generous pile of fries. So it's an economical, filling option. That's appealing. But I think the answer is a little more complicated than that. It's not just that burgers are cheap, it's that they're easy to eat. Because the meat is ground up, you don't have to do much chewing. Because it's served on a bun, it's easy to eat. There's no cutting, only lifting. And because burgers come with an array of sides, you can build yours to your own taste. That's appealing too. Another factor may be familiarity. Sometimes, when we go out to eat, we don't want to be challenged. We want the taste of the familiar and nothing's more familiar, at least to Americans, than the taste of a burger. Specifically the char that appears on the exterior of the meat after it hits the hot flame; that specific smell and taste...

...English 1157 Professor Tom Kiczula 28 November 2011 Burger King Family Bundle I have had a few bad experiences with fast food in the past – from raw chicken nuggets from McDonald’s to Popeyes chicken with hair, to people throwing my drink at me at Burger King – so I gave up eating fast food for almost two years. Finally, I came to college and with no time to cook I resorted back to fast food. I began slowly by just eating a burrito from time to time from Taco Bell, then I got a few salads from Wendy’s, and finally some onion rings from Burger King. As a child I would always beg my mother to take me to Burger King for onion rings, they were as good as I remembered. On this particular visit to Burger King I noticed a huge sign advertising the Family Bundle. I did not read much about it. I just noticed there seemed to be a lot of food for only $9.99, and I was intrigued. Later on I went online to do a bit of research about the family bundle. I learned that the family bundle consists of food for parents and a child: one Whopper, one Whopper Jr., two small fries, two small drinks and one of its boxed kid’s meals [containing a kids fries, four chicken nuggets, a kid’s drink, and a Happy Feet toy]. Burger King used the Family Bundle name in August as part of its national coupon drop. At that time the Family Bundle gathered a Whopper, Whopper Jr., 10 Chicken Tenders, three small fries, three small drinks and two pies for $9.99.

...goodwill and consumer trust, they must deal with various events and forces in the environment. This paper deals with the major forces in the environment as they affect McDonalds. Competitive Forces McDonalds is the world’s number one fast-food company by sales, with more than 31,800 flagship restaurants serving burgers and fries in more than 100 countries. Almost 30% of its locations are company-owned; the others are run by franchisees. Sales in 2005 were $20,460.2 million and 447,000 people were employed world wide. [i] McDonalds’ major competitors are Burger King, the number two hamburger chain, and Wendy’s, number three. McDonalds also competes with Yum Brands, Inc., “which actually is the largest fast-food operator in the world in terms of number of locations, with more than 34,000 outlets in more than 100 countries. Yum Brands restaurants include the number 1 chicken fryer, KFC (with more than 13,500 units), top pizza joint Pizza Hut (about 12,500), and quick-service Mexican leader Taco Bell (more than 6,000). Yum Brands also operates the Long John Silver’s seafood chain, along with several hundred A&W root beer and burger stands”[ii] Economic Forces McDonalds is an elastic good and has many substitutes, from the competitors mentioned above to food cooked at home. Given that it is less expensive to cook at home, people whose incomes are squeezed may decide to avoid fast food all...

...Organizational culture Many researchers and practitioners have been interested in organization culture. Although much confusion and discussion about the concept still exists, organization culture has not disappeared from literature and practice. De Witte, Van Muijen. (1999). To shed light on the basic idea of culture and culture being widely used in the context of organizations, Culture is relatively stable set of beliefs and values that are generally held by a society (Lim, 2008). Considering this view of culture, Organization culture can be defined as “a pattern of basic assumptions – that has worked well enough to be considered valid and, therefore, to be taught to new members as the correct way to perceive, think and feel.” (Schein, 1985). The basic assumptions guide decision makers in dealing with problems of the external environment and integrating the behaviours of organizational members. Considering the relationship of culture with performance Considering what makes culture strong, According to Chatman and Eunyoung (2003) “strong cultures are based on two characteristics which are high levels of agreement about what is been valued and high intensity about these values”. If both are high a strong culture exists and if both are low the culture is not that strong at all. Though strong organizational cultures have been considered as critical to bottom-line performance of larger organizations (Collins, Porras,2002)., newer evidence suggests that developing a strong and...

...Burger King Introduction Burger King is the world’s largest flame broiled fast food restaurant chain. As of 2011, Burger King operates restaurants in 12,300 locations serving over 11 million guests daily in 76 countries and territories worldwide (Burger King , 2011). Burger King’s core competency is its unique flame-broiled burgers. This process is difficult to imitate and helps differentiates Burger King from other fast food chains that fry their burgers instead. So much so in fact, no other fast food provider flame broils their burgers. In addition, Burger King allows and encourages consumers to customize the unique flame-broiled burgers with options to their liking. This creates a win-win situation for both Burger King and the consumer. Burger King has the benefit of offering a different product and the consumer benefits by having numerous burger options. Although Burger King has expanded its menu selections, they have remained true to their original flame-broiled burgers. This product gives them an advantage over other fast food chains. Facing intense competition and limited growth opportunities domestically, Burger King hopes strengthen their competitive stance through international expansion. By mid 2009, Burger King was not in any of the following countries: France, India, Nigeria, Pakistan and South Africa. Compare these countries as possible future locations for Burger King. In looking for new countries to enter, Burger King needs to identify countries that...
