Same as any other area in computer science, viruses become a great deal indeed throughout the years. Return to the origin of computer viruses, although there were no viruses or worms developed, Mathematician John Von Neumann had described the theories of self-replicating programs in 1949. In 1971, Bob Thomas has developed “The Creeper Virus”. It was an experimental self-replicating program. It infected DEC PDP-10 Computers to run the TENEX Operating System. The Reaper program was later developed to delete this virus. In 1974, a virus called the Rabbit (or Wabbit) is written. The Rabbit virus made multiple copies of itself at a high speeds until it clogs the system and finally crashing the computer system. In 1975, John Walker has developed the ANIMAL for the UNIVAC. It spread to others multi-user UNIVACs when computer users discovered the game due to overlapping permissions when tapes were shared. John Brunner has published the novel called “Snockwave Rider” that coining the word “worm” to explain a program that circulates itself via a computer network. In 1981, a program called “Elk Cloner” has created by Richard Skrenta for Apple II System. The Apple DOS 3.3 was infected and propagates to others computers by floppy disk transfer. “Elk Cloner” was the first computer virus outbreak in history. In 1983, Frederick Cohen has coined the word “virus” in explaining self-replicating computer programs. In 1986, a path to displace the executable code found in the floppy disk was found by two programmers from Pakistan. On January, the Brain boot sector virus which also known as Lahore, Pakistani, Pakistani Brain, and Pakistani flu is released. In 1987, Yale University has developed a virus called Lehigh. It infected command.files and was i... ... middle of paper ... ...as found in a digital photo frame. Another Trojan horse known as Torpig affects Windows by turning off anti-virus applications. In July of 2009, cyber attacks occur and the W32.Dozer attack the United States and South Korea. Passwords for online games were steeled by the Daprosy Worm. It intercepts all keystrokes and sends to its author which is a very dangerous worm that can affect business-to-business systems. In June of 2010, a Windows Trojan called Stuxnet was found. It was the first worm to attack the SCADA systems. In September, the Kenzero virus spreads online form peer to peer. In 2011, SpyEye and Zeus merged was appear. It uses to attack mobile phones to obtain banking information. A Trojan horse called Anti-Spyware 2011 attacks newer Windows versions like Vista and XP. It disables the access of internet for virus updates and security for antivirus programs.
Bob is at the skate park, showing off his skills as a skateboarder. With one wrong move, he fell off of his skateboard, and his knee scrapped on the concrete, causing a big gash on his knee. A virus enters in the knee, and it has a mission. Its mission is to infect every organ in Bob's body.
On August 12, 2003, a computer worm was released called MSBlaster.B, which was distributed through two files “teekids.exe” ( which included code that directs compromised computers to attack the Microsoft domain name www.windowsupdate.com and a backdoor file “Lithium” ( which allows a way into a password protected system without use of a password and remote control a system). The worm itself targeted mostly Windows 2000 & Windows XP systems. If Windows NT or Windows 2003 servers do not have the appropriate patches, they too may be vulnerable. The function of the worm is to exploit the DCOM RPC vulnerability.
The ones who would like to publish this virus and the ones who do not both reasonable reasons for their thoughts. Anthony S.Fauci, mentioned in The Deadliest Virus, says that publishing this can help scientists to determine if the existing vaccines or drugs will be enough to cure this virus. Publication of this can help us to develop better cures for worse viruses. In addition, people will know how deadly it is and if they get the virus, they will know what it is. On the other hand, Michael Specter gave an example of Clinton’s speech about bioterrorism. Hilarity Clinton says, “Evidence in Afghanistan...Al Queda in the Arabian Peninsula made a call to arms for – and I quote – ‘brothers with degrees in microbiology or chemistry to develop a weapon of mass destruction”. Clinton’s speech brings up the concerns of some scientists about the publication of the virus. Her speech shows that if the virus is open to the public, other countries will find a way to get this virus and might develop it as weapon for
Beal, V. (2011, March 29). The difference between a computer virus, worm, and Trojan horse.
Bill Gates may also be responsible for one of the first computer viruses. While working for a company called the Computer Center he discovered the machine was connected to a national network of computers called the Cybernet. He invaded the network and installed a program on the main computer that sent itself to the rest of the networks computers, making the main computer crash. When he was found out, he was punished severely by being banned from computer use the rest of his junior year. That is when he began to focus on college and law school. By the next year he was back to helping write a class scheduling program for the schools computer.
At the Aim Higher College there have been recently discovered malware on the campus systems that are due to many recent attacks. I used an Anti-virus protection software called AVG on the computer systems on campus and ran a whole computer scan. The results came back very quick of numbers of malware being high and medium priorities that these should not be taken lightly. Furthermore, the scan found many viruses, Trojans, and malicious software and applications.
As the timeline for Stuxnet is still being researched, we understand that the main Stuxnet code was discovered around June 2010, by a security com...
Having first appeared in Russia in 2005, referred as Winlock, that successfully scammed over £10m from unsuspecting victims before the Russian authorities arrested 10 individuals for involvement in such hackings in 2010, however it hasn’t stop the growing number of the problem. With such profitable money to obtain, perpetrators have discovered new ways to spread the malware and to cash-in at the expense of victims.
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.
In this globalized arena, with the proliferating computer users as well as computer networks, risks associated like Malware attacks are also multiplying. As the proverb
Malicious code, also known as malware, installed on a computer provides an attacker with the control over this machine. Therefore, malware can be defined as “a set of instructions that run on your computer and make your system do something that an attacker wants to do”. It is more common to see malicious code to be implemented in binary executable files. However, it can be implemented in almost any computer language. Attackers have used a huge number of scripting languages, word processing macro languages and a h...
Virus is one of the most common malware. Unlike spyware, virus is largely designed to harm useful programs or wreck down an entire operating system. There are many ways through which virus may enter a computer. The most common way is via email attachments. A...
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.
A cyber crime called 'Bot Networks', wherein spamsters and other perpetrators of cyber crimes remotely take control of computers without the users realizing it, is increasing at an alarming rate. Computers get linked to Bot Networks when users unknowingly download malicious codes such as Trojan horse sent as e-mail attachments. Such affected computers, known as zombies, can work together whenever the malicious code within them get activated, and those who are behind the Bot Networks attacks get the computing powers of thousands of systems at their disposal.
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.
