is weaker than the importance of what the system is protecting. In this case of DDoS attacks, the usernames and passwords had been hardcoded into the system or used default ones that made security for them weak. By exploiting this vulnerability the botnet was able to infect the system and go into the controls where they made the traffic coming in appear offline. Another vulnerability is the unsecure communication between devices. This essentially comes down to the main principles of cybersecurity.

According to Whitman (2012) “In a denial-of-service (DoS) attack, the attacker sends a large number of connection or information requests to a target. So many requests are made that the target system becomes overloaded and cannot respond to legitimate requests for service.” (P.67). The system could crash or basically become unable to perform normal functions. Most DoS attacks are led by a planning phase in which many systems, perhaps thousands, are compromised. The compromised machines are turned

sequences for the normal and botnet systems are computed. If the observation sequence’s ALL value lies in a particular confidence interval, then it will be considered as normal profile. Similarly confidence interval for botnets is identified. If the observation sequence’s ALL lies within this confidence interval, then it will be considered as botnet communication. 3.4 EXPERIMENTAL RESULTS Using the experimental setup, Spyeye, Blackenergy, Zeus, Athena and Andromeda botnets are installed. Zeus, ZeuS

The United States suffered a blow to the economic infrastructure leading to loss of the use of bank accounts, automated teller machines along with non-access to bank accounts from a large denial of service attack. This poses a clear issue to the United States infrastructure which could lead to identity theft of bank information as well as other critical infrastructure being targeted as a result from this successful attack. Beyond losing the access to the accounts of the citizens of the United States

On development of science and technology, the network technique is more and more advance and important. A lot of malware has appeared on the Internet. Malware is described some unsafe software, such as computer viruses, Trojan horses and spywares. Recently, it uses in order to invade any computer. Malware is exploited by hackers and governments to steal personal, financial or state secrets. Malware is typically used against hackers to gain information like personal identification numbers, credit

this critical piece of cyber equipment, the network would be left undefended and at the mercy of hackers and criminals. Without this crucial piece of cyber equipment, the computers would be left unprotected and would quite possible be enlisted by botnets to become members of their zombie

Hypersexualization of young girls in America and Europe the hyper-sexualization of American youth culture paints a disturbing picture of UggCybercrime trends and courses in Kenya Today we are going to talk about the cybercrime trends and courses in Kenya. As we know that Kenya is a place with literally high rate of crime in almost all regions. This Crime rate is basically from the major places of Kenya like Nairobi, Mombasa, Kisumu, and coastal beach resorts. Cyber security of Kenya is rapidly evolving

component of SDBot connects to an IRC server and lies silently waiting for instructions from the botmaster. This aforementioned code structure, a standard core package attached with customized patches, has made SDBot arguably the most active and popular botnet. As of August 2004, SDBot has been reported to have

Information security is claimed to be a management problem in some aspects. Many businesses and government managers drift away from information security because, they portray it to be a complex task that's out of their reach. Information security is not 100% based on just technology alone, but rather than management itself. Many managers believe that more technology is the solution to technology problems, but that's far from the truth. Management has certain abilities that technology can't do for

With the growth of mobile device, cloud and internet, we are witnessing a rise in cyber-crimes. Cyber-attacks result in breaches to data security and sabotage. Personal data, intellectual property, physiological harm are easy targets. for a data security breach. Attacks can result in commercial losses, disruption of operations and the possibility of extortion. Cyber-attacks may also expose an organization to regulatory action, and damages can occur from loss of trust among customers and suppliers

He explains because the internet is so sufficient at self-regulating there is no need for legislations to effect the internet because it is unpredictable. For example, he explains that at various points throughout the history of the internet, many botnets and viruses have spread through the net, however due to the help of many volunteers co-operating the internet has been very successful of preventing and stopping any domino

Cyber Attacks In the early 1970s the internet was introduced to the world and few people were using it. But now millions of people are using internet all the time either in home, work, driving, or in malls. This discovery has introduced a new type of crimes which called cybercrimes or computer crimes. The people behind cybercrimes are called hackers and what they do is hacking into other computers to steal form them. They can hack into any device that connected into the internet and control it to

black-hat hackers are the unethical hackers and illegal action like hacking into proprietary system, violate computer security of stealing personal information such as stealing the credit card numbers or for pure maliciousness using or creating that botnet to perform DoS attack consists of sending huge amount of traffic to certain websites. From the Appendix I of the Case Study 1 is an example for black-hat hacker because the two suspects

Healthcare is becoming more dependent on technology. From advancements in hardware that help to save lives and cure disease, to software that allows for the transferring and storage of private patient data. Healthcare systems also rely on technology to control costs and ensure an optimal patient experience. The drawback to these innovations is that hospitals have seen a marked increase in the use of electronic information and a resulting increase in the level of exposure to cyberattacks, which target

⅔ of households were hit with identity theft in 2013. (Minnick, 10) Cyber attacks come in many different forms and can be extremely hard to combat. Letters sent through email can be dangerous as well, containing tricks and scams to steal the user’s information. Equally dangerous, when identity theft occurs it can be hard to get rid of. Some cyber attacks seem simple, however the most effective are always the cleverest. Cyber attacks can come in many different forms, but one of the most dangerous

Cyber security is gaining tremendous attention nowadays due to the increasing use of internet, computers by the media and various public and private institutions. They recognize the terrible impacts with the cyber attacks. At present, cyber attacks has resulted in computer based criminal activities which are generating worldwide threat, destruction and disruption. There is no cross border for cyber activities and the increase in the use of internet by the world wide users and lack of international

Barclays is the 7th largest bank in the world having more than 48 million clients around the globe. Since the 1970’s the way of banking began to change worldwide: in 1966 the first credit card (Barclaycard) of Barclays was issued, a year after clients were introduced to the first Barclays’ “robot cashier” which is now better known as ATM. The following events of technological development had sound effect on banking and the way we see it now. With possibility to make almost every transaction, investment

cybercrime victims each day globally, costing the global economy approximately $113 billion per year (“Symantec”). These crimes can be divided into three broad areas including attacks against computer hardware and software. For example, botnets, malware and network intrusion. Financial crimes, such as online fraud, penetration of online financial services. Finally abuse, especially of young people, in the form of bullying over social media (“Interpol”). Cybercrime is a problem in the United

The operation was code name Buckshot Yankee. Operation Buckshot Yankee was the United States response to the terrorist attacks of 2008. Unlike the terrorists’ attack on 9/11, the attack on 2008 was a cyber-attack that affected the U.S Government’s unclassified and classified computer networks. The Deputy Secretary of Defense William J. Lynn III (2010) stated “It was a network administrator 's worst fear: a rogue program operating silently, poised to deliver operational plans into the hands of an
