The Use Of Hack Into A Single Or Networked Computer

This utilizations two sorts of assaults Dictionary assault and Brute Force Attack for hacking wifi passwords.

Often attacks are based on software bugs that a hacker can use to give himself or herself super-user status. Also one can get a copy of the password file (which stores user names and encrypted passwords and is often publically accessible) and either do a brute-force attack trying all possible combinations, or encrypt a dictionary and compare the results to see if anyone choose a password that is a dictionary word.

18.) Brute force When password guessing, this method is very fast when used to check all short passwords, but for longer passwords other methods such as the dictionary attack are used because of the time a brute-force search takes.

A hacker is a person who breaks into computers, usually by gaining access to administrative controls. There are several types of hackers. The black hat is someone who breaks computer security without authorization or uses technology for credit card fraud, identity theft, and piracy. A security exploit takes advantage of a known security weakness. These are very common in website/domain hacking. A packet sniffer is an application that captures data packets, which can be used to capture passwords and other data in transit over the network. A spoofing attack involves one program, system, or website by pretending to be the real trusted program, system or website and then stealing your usernames and passwords. A keylogger is a tool designed to record every keystroke on an affected machine stealing user's passwords.

Drupal makes brute force attack more difficult because it limits the number of login attempts from a single IP address over a period of time. The

Linton (2011, p.44) stated that hacking of network of common users and attacking their personal computers is one of the most threatening problems at present. It is happening in every second that results in a loss in several ways like loss of credentials, personal information etcetera. Although the use of personal computers and the internet has been increased rapidly, numbers of users who are the expert and have good knowledge to tackle the matters are very rare. In addition, time, as well as required equipment to protect hacking, is also very.

There are many types of hackers in the world. One group of hackers focuses on breaking copy protection schemes. Copy protection schemes prevent the illegal copying of software, music, etc. By cracking these schemes, people are then able to use and copy the item without the copy protection preventing or hindering their use. This process is commonly known as cracking and the hackers involved in the process are known as crackers. Cracking is commonly viewed as an illegal act in many countries as it is typically used to steal copies of the copyrighted item. However, there are benefits to cracking. It can remove the inconveniences the copy protection scheme imposes on users and in some

Guessing passwords: Another common attack is to guess a user's password. This style of attack is manual or automated. Manual attacks are laborious, and only

During this project, we will solve the problem using both parallel and sequential methods. A performance analysis will be carried out on both methods to determine the efficiency and speed of each. The sequential algorithm will be written in both pseudo-code and the C++ language. The parallel method will also be written in pseudo-code but we will be using C and MPI instructions to achieve the parallelism of the operation. We would be using the Midwestern State University Turing cluster and personal Ubuntu virtual machines to implement both the parallel program and the sequential program. We as a group decided to pursue this topic as passwords play a vital part in how the world’s information is secured and verified. Passwords are used for user authentication to prove identity or access approval to gain access to a resource. Passwords remain the single most common point of failure in system security. Ensuring that passwords cannot be efficiently broken is important for encryption algorithms. Due to this, we decided to design a sequential and parallel algorithm that would be successful in cracking a password. Given an opportunity to research any topic where parallel programming may prove useful, we agreed on a brute-force algorithm. In our upcoming project, we would all attempt to design, implement, and analyze the brute-force algorithm.

There are two types of theses but both have their own problems. The first "checks every password possible from the entry site." (1) The second uses a program that goes in and reads the passwords off. The problem with both is that you have to "get the cracker into the site, undetected"(1) You also must cover you trail. Some prefer the manual method first. "There are actually lists of 100(or more) most-used passwords."(2) Hackers have reported that, "a simple password that appears in the English dictionary will take about an hour or less for a hacker to crack."(4) "This is not considered a long time to a hacker."(Brian 2) Third, they use what is called web spoofing. This is the most dangerous because they see what every you are doing. They can get you passwords plus any other information you might have. This web spoofing is caused by a middle man who can redirect information from your page, to his page, to the page you were sending the information to. "The middle man sees all."(How are they getting my password? 3) This is above all the easiest way to get any information that they might want or need. The last method is through Java. Through a program they can hack into a computers hard drive through your Java program. That is why if you can avoid keeping your passwords on your hard drive do it. Some people keep their passwords on three by five cards and store them which is allot safer. The best method to

Another type of cyber-attack that will affect the business is accomplished with brute force. With a brute force attack, an advanced algorithm is devised to do anything and everything to attack the company’s operating system. The attack achieves this by exploring and probing for weaknesses contained by the system, generally through password-protected structures. These cyber-attacks not only influence our business agenda, but they can also trigger a disruption in how our business pursues significant goals and the precedence that have erected our foundation for a balanced organization.

The term “hacking”, as defined by Dictionary.com, is “to cut, notch, slice, chop, or sever (something) with or as with heavy, irregular blows.” This is exactly what cyber criminals are doing today, slicing through counter measures to obtain digital knowledge, which is then sold on the black market or hacking sites with formats similar to eBay. From there, depending on the information, it is used to open up credit card accounts, apply for government benefits, and other forms of identity theft. The means by which they do this is only limited to expertise and creativity. Once inside a computer or network, a hacker may then let loose his/her entire arsenal of destruction including, but not limited to, viruses,

In the computer security context, a hacker is someone who seeks and exploits weaknesses in a computer system or computer network (Wiki).

Intrusion or Hacking : If a computer is used and controlled by unauthorised users then it is called hacking and who does this is called hacker. Main purpose of hacking to steal the private data or alter the actual data.

In addition, another type of experiment is conducted regarding the brute force attack on the
