The history of cybercrime goes back to 1971 and the first computer virus called the Creeper which was created by Bob H. Thomas, who was a BBN engineer (Dalakov, Meltzer, and Phillips). BBN which stands for Bolt, Beranek and Newman, is now Raytheon BBN Technologies (“About”, Dalakov). A computer virus is a program that is created to cause damage to a computer or perform other malicious acts (204). The Creeper virus was designed to infect the ARPANET network. The ARPANET, which stands for Advance Research Projects Agency was set up by the U.S. Government as an agency in 1969 to provide a network of computers that would connect various academic and research organizations; it was the predecessor of the Internet (“Internet”, Morley, and Parker). The creeper was not really nasty, the “infected computers would simply display the message, I'm the creeper: catch me if you can” the computers did not suffer any lasting damage (Benford 112, Meltzer, and Phillips). The Creeper virus was an experiment of a self-replicating program, not designed to damage but to demonstrate a mobile application (Dalakov). Self means doing on its shelf (“Self”). Replicating means repeating over and over again in exact the same way (“Replicate”). Both these words are combined as Self–replicate is to copy itself automatically (“Self-replicating”). A computer program is executable software that runs on a PC or computer system (Christensson). An executable file is a type in a computer file that runs a program when it opens (Christensson). Software is the instructions tell the computer what to do (“Software”). Software is the entire set of programs, procedures, and routines associated with the operation of a computer system, including the operating syst... ... middle of paper ... ... to get user data back (“Ransomware”). This means that criminal is using a computer by locking your computer by passing your permission on the computer. This makes it possible to make millions of dollars by making viruses and scams in less than one hour (ComputerCareClnc). In the computer world we will never find the true answer. Why do people create computer viruses? Why they benefit from it? It is like asking why do people commit crimes? (Why People Create Computer). In the 20th century at the beginning of early computer viruses. They were for experiments, annoyance, and testing. They do not really harm computer systems or computers back then. In the 21st century computer viruses, are changing. They are becoming smarter and more destructive rarely without annoyance but they serve a purpose to cause some harm to a computer or computer systems (Benford).
The malicious software can lock the data in a way that is not difficult for an expert to reverse (Ali 89). Nevertheless, there is a more advanced method that involves the use of cryptoviral extortion to encrypt data and demand a ransom to decrypt the data. In such case, it is difficult for experts to recover files without a decryption key (Ali 89). Ransomware attacks are normally executed using a Trojan or a file that is disguised as an email attachment that seems legitimate to the user. In the last five years, ransomware attackers were able to target multiple computers through the use of a botnet (Ali 88). A botnet enables cyber criminals to attack an entire system by compromising the network. The ability to kidnap multiple systems makes ransomware a significant cyber security threat. The cybercriminals demand ransom in the form digital currencies such as bitcoins and ukash because they are difficult to
A computer virus is designed to self-replicate, self-install, and attack the root functions and system of different programs without authorization or the user’s knowledge. Virusesmainly affect the root of a computer system.Virus can destroy and damage most important part of our hard drive, the boot sector, where information about all files has been stored. Viruses may alter directory paths and may change
What is virus? A computer virus, according to Webster's Collegiate Dictionary, is "a computer program usually hidden within another seemingly innocuous program that produces copies of itself and inserts them into other programs or files, and that usually performs a malicious action (such as destroying data)". Two categories of viruses, macro viruses and worms, are especially common today. Computer viruses are never naturally occurring; they are always man-made. Once created and released, however, their spread is not directly under human control. One example of a virus is the Anna Kournikova virus, which comes in the form of a picture sent through email.
Ransom by definition: a sum of money demanded or paid for the release of a captive. With this, one can somewhat tell what ransomware is - a class of malware which restricts access to the computer system that it infects, and demands a ransom paid to the creator of the malware in order for the restriction to be removed. Standing strong as one of the most destructive and profitable malware till date for the perpetrators, it is reported “Since last couple of weeks we have been seeing 500+ incidents per day of this malware. The incidents are being reported from all over India.” says Mr. Katkar, CTO of India’s leading antivirus software Quick Heal, dated early September.
Most viruses are created out of curiosity. There are those out there who create them out of malice, but far more of the creators are just meeting a challenge, to see if they can do it or not. A common type of virus would be a Trojan Horse, a destructive program disguised as a game, a utility, or an application. When run a Trojan Horse does something harmful to the computer system, while appearing to do something useful. A worm is also a popular type of virus. A worm is a program that spreads itself across computers, usually by spawning copies of itself in each computer’s memory. A worm might duplicate itself in one computers memory so often that it causes the computer to crash. A worm is introduced secretly into a host system either for fun, or with the intent to damage or destroy information. Now I will explain some of the more major viruses, and how they function.
Hacking has been around since the birth of computers. When the term hacking was first used, its meaning was not that of how we think of it today. At the origins of computing, a hacker was considered to be just a "creative programmer (Baase, 2003)." Early forms of computer games as well as the beginnings of operating systems were discovered and created by these original hackers. These hackers plunged into systems as a way of an intellectual challenge and to aspire to gain knowledge (Baase, 2003). Kevin Mitnick believes he falls into this realm of hackers. Hackers in today's era are now looked upon as criminals who invade the privacy rights of individuals and have the ability to deliver worms/viruses. The differences are that hackers today have full intentions of delivering terrible viruses and worms. Mitnick was one of the most infamous hackers during the 1980's. He molded his hacking style around the stupidity of humans and his quest for intellectual knowledge. The ways in which he wiggled his way into computer systems extenuates many of the issues surrounding computer security and privacy.

Erin Heard Fluency in IT Mrs. Murimi October 2nd, 2017 Viruses In 1982, a program called “Elk Cloner” was the first computer virus to appear “in the wild”, that is, outside the single computer or “computer” lab where it was created. It was written in 1981 by Richard Skrenta while in the ninth grade at Mount Lebanon High School near Pittsburg. The virus spread by infecting the Apple DOS 3.3 operating system using a technique now known as a boot sector virus. It was attached to a game which was then set to play.
There is also a set of programs that are related to viruses by virtue of their
In today’s days malware is designated as a software which aims to disturb a computer with the consent or permission of the owner. This term “Malware” is used by computer professionals to describe a varied forms of destructive, annoying and intrusive software code. This word “Malware” is used to indicate all types of malware which include a true set of viruses.
What is the “MALWARE”? A malware refers to software programs designed to damage or do other unwanted actions on a computer system. In Spanish, "mal" is a prefix that means "bad," making the term "bad ware" .Malware includes viruses, worms, Trojan horses, and spyware. Viruses, for example, can cause havoc on a computer's hard drive by deleting files or directory information. Spyware can gather data from a user's system without the user knowing it. This can include anything from the Web pages a user visits to personal information, such as credit card numbers.
Imagine having a computer without running software. Computers would be slightly pointless without programs to run it. There would be no directions in the computer to tell it how to run, where to run, and what to do. A computer would have the ability to turn on, but a blank screen would be the only thing to appear on a monitor. I am sure that the question of "Who creates these programs?" has run through many minds in the past. These programs aid you in typing papers, connect you to the Internet, send information to other computers, or provide an interface for games that help to occupy your time. Computer programmers are the individuals that create and work with these programs. On a broad scale, computer programmers write the programs, test the programs, and then maintain the programs that millions of people use daily (Computer Programming 243-249). The every day duties of a computer programmer include investigating work requests from system analysts, understanding the problem and the desired resolution, choosing an appropriate approach, and planning an outcome that will tell the mechanism what to do to produce the desired results. Programmers must be experienced in high levels of mathematics, computer science, and programming languages. A programmer must also have experience with critical thinking, reading comprehension, and deductive reasoning. Programmers need to master these subjects, since they write in a language different from everyday English or French.
Malicious software, or simply malware, can be described as software that a computer user never authorized to be loaded. This means that the software can be found on user’s computer without his or her knowledge. Furthermore, a malware can be described as software that collects private information from any computer without user’s knowledge and authorization. As the name suggests, this software is malicious and can do great damage to a computer, mobile device, or other related devices. This damage can range from something as slight as altering the author’s name on a document to massive damage like making an entire device fail to function properly (Töyssy and Marko 109). The good news is that malwares can be controlled or prevented. As a matter of fact, it does not cost a fortune to keep a device safe from malware attacks. It also needs enough knowledge about them. In order to be able to do this, however, it is important to understand the various terminologies used to describe malicious software.
One could be the money they can get from selling top secret information, or some may be bitter and want revenge. A script kiddie is someone who is like a cracker because they may have the intentions of doing harm, but they usually lack the technical skills. They are usually silly teenagers that use prewritten hacking and cracking programs. A corporate spy has extremely high computer and network skills and is hired to break into a specific computer or computer network to steal or delete data and information. Shady companies hire these type people in a practice known as corporate espionage. They do this to gain an advantage over their competition an illegal practice. Business and home users must do their best to protect or safeguard their computers from security
A program is a sequence of instructions that tells the hardware of a computer what operations to perform on data. Programs can be built into the hardware itself, or they may exist independently in a form known as software. In some specialized, or "dedicated," computers the operating instructions are embedded in their circuitry; common examples are the microcomputers found in calculators, wristwatches, automobile engines, and microwave ovens. A general-pur pose computer, on the other hand, contains some built-in programs (in ROM) or instructions (in the processor chip), but it depends on external programs to perform useful tasks. Once a computer has been programmed, it can do only as much or as little as the software controlling it at any given moment enables it to do. Software in widespread use includes a wide range of applications programs-instructions to the computer on how to perform various tasks.
