Pharming
Pharming is a cyberattack intended to redirect a website's traffic to another, fake site by installing a malicious program on the victim's computer in order to gain access to it. Pharming can be conducted either by changing the hosts file on a victim's computer or by Exploit (computer security), exploitation of a vulnerability (computing), vulnerability in Domain name system, DNS server software. DNS servers are computers responsible for resolving Internet names into their real IP addresses. Compromised DNS servers are sometimes referred to as DNS spoofing, "poisoned". Pharming requires unprotected access to target a computer, such as altering a customer's home computer, rather than a corporate business server. The term "pharming" is a neologism based on the words "farming" and "phishing". Phishing is a type of social engineering (computer security), social-engineering attack to obtain Authentication, access credentials, such as user names and passwords. In recent years, both phar ...

DNS Spoofing
DNS spoofing, also referred to as DNS cache poisoning, is a form of computer security hacking in which corrupt Domain Name System data is introduced into the DNS resolver's cache, causing the name server to return an incorrect result record, e.g. an IP address. This results in traffic being diverted to any computer that the attacker chooses. Put simply, a hacker makes the device think it is connecting to the chosen website, when in reality, it is redirected to a different website by altering the IP address associated with the domain name in the DNS server. Overview of the Domain Name System A Domain Name System server translates a human-readable domain name (such as example.com) into a numerical IP address that is used to route communications between nodes. Normally if the server does not know a requested translation it will ask another server, and the process continues recursively. To increase performance, a server will typically remember (cache) these translations for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Online Identity Theft
Identity theft, identity piracy or identity infringement occurs when someone uses another's personal identifying information, like their name, identifying number, or credit card number, without their permission, to commit fraud or other crimes. The term ''identity theft'' was coined in 1964. Since that time, the definition of identity theft has been legally defined throughout both the UK and the U.S. as the theft of personally identifiable information. Identity theft deliberately uses someone else's identity as a method to gain financial advantages or obtain credit and other benefits. The person whose identity has been stolen may suffer adverse consequences, especially if they are falsely held responsible for the perpetrator's actions. Personally identifiable information generally includes a person's name, date of birth, social security number, driver's license number, bank account or credit card numbers, PINs, electronic signatures, fingerprints, passwords, or any other informat ...

Phishing
Phishing is a form of social engineering and a scam where attackers deceive people into revealing sensitive information or installing malware such as viruses, worms, adware, or ransomware. Phishing attacks have become increasingly sophisticated and often transparently mirror the site being targeted, allowing the attacker to observe everything while the victim navigates the site, and transverses any additional security boundaries with the victim. As of 2020, it is the most common type of cybercrime, with the Federal Bureau of Investigation's Internet Crime Complaint Center reporting more incidents of phishing than any other type of cybercrime. The term "phishing" was first recorded in 1995 in the cracking toolkit AOHell, but may have been used earlier in the hacker magazine '' 2600''. It is a variation of ''fishing'' and refers to the use of lures to "fish" for sensitive information. Measures to prevent or reduce the impact of phishing attacks include legislation, user educa ...

Antivirus Software
Antivirus software (abbreviated to AV software), also known as anti-malware, is a computer program used to prevent, detect, and remove malware. Antivirus software was originally developed to detect and remove computer viruses, hence the name. However, with the proliferation of other malware, antivirus software started to protect against other computer threats. Some products also include protection from malicious URLs, spam, and phishing. History 1971–1980 period (pre-antivirus days) The first known computer virus appeared in 1971 and was dubbed the " Creeper virus". This computer virus infected Digital Equipment Corporation's ( DEC) PDP-10 mainframe computers running the TENEX operating system.From the first email to the first YouTube video: a d ...

Spyware Removal Software
Spyware (a portmanteau for spying software) is any malware that aims to gather information about a person or organization and send it to another entity in a way that harms the user by violating their privacy, endangering their device's security, or other means. This behavior may be present in other malware and in legitimate software. Websites may engage in spyware behaviors like web tracking. Hardware devices may also be affected. Spyware is frequently associated with advertising and involves many of the same criticism of advertising, issues. Because these behaviors are so common, and can have non-harmful uses, providing a precise definition of spyware is a difficult task. History As personal computers and broadband connections became more common, the use of the internet for e-commerce transactions rose. Early retailers included book dealer Amazon.com and CD retailer CDNow, CDNOW.com, which both were founded in 1994. As competition over customers intensified, some e-commerce ...

Desktop Computer
A desktop computer, often abbreviated as desktop, is a personal computer designed for regular use at a stationary location on or near a desk (as opposed to a portable computer) due to its size and power requirements. The most common configuration has a computer case, case that houses the power supply unit (computer), power supply, motherboard (a printed circuit board with a microprocessor as the central processing unit, computer memory, memory, bus (computing), bus, certain peripherals and other electronic components), disk storage (usually one or more hard disk drives, solid-state drives, optical disc drives, and in early models floppy disk drives); a computer keyboard, keyboard and computer mouse, mouse for input (computer science), input; and a computer monitor, monitor, computer speakers, speakers, and, often, a printer (computing), printer for output. The case may be oriented horizontally or vertically and placed either underneath, beside, or on top of a desk. Desktop Comput ...

Laptop
A laptop computer or notebook computer, also known as a laptop or notebook, is a small, portable personal computer (PC). Laptops typically have a Clamshell design, clamshell form factor (design), form factor with a flat-panel computer screen, screen on the inside of the upper lid and an alphanumeric keyboard and pointing device on the inside of the lower lid. Most of the computer's internal hardware is in the lower part, under the keyboard, although many modern laptops have a built-in webcam at the top of the screen, and some even feature a touchscreen display. In most cases, unlike tablet computers which run on mobile operating systems, laptops tend to run on desktop operating systems, which were originally developed for desktop computers. Laptops are used in a variety of settings, such as at work (especially on business trips), in education, for PC game, playing games, Content creation, content creating, web browser, web browsing, for personal multimedia, and for general P ...

Cyberattack
A cyberattack (or cyber attack) occurs when there is an unauthorized action against computer infrastructure that compromises the confidentiality, integrity, or availability of its content. The rising dependence on increasingly complex and interconnected computer systems in most domains of life is the main factor that causes vulnerability to cyberattacks, since virtually all computer systems have bugs that can be exploited by attackers. Although it is impossible or impractical to create a perfectly secure system, there are many defense mechanisms that can make a system more difficult to attack, making information security a field of rapidly increasing importance in the world today. Perpetrators of a cyberattack can be criminals, hacktivists, or states. They attempt to find weaknesses in a system, exploit them and create malware to carry out their goals, and deliver it to the targeted system. Once installed, the malware can have a variety of effects depending on its purpose. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Network Router
A router is a computer and networking device that forwards data packets between computer networks, including internetworks such as the global Internet. Routers perform the "traffic directing" functions on the Internet. A router is connected to two or more data lines from different IP networks. When a data packet comes in on a line, the router reads the network address information in the packet header to determine the ultimate destination. Then, using information in its routing table or routing policy, it directs the packet to the next network on its journey. Data packets are forwarded from one router to another through an internetwork until it reaches its destination node. The most familiar type of IP routers are home and small office routers that forward IP packets between the home computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks to powerful core routers that forward data at high speed along ...

Local Area Network
A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, campus, or building, and has its network equipment and interconnects locally managed. LANs facilitate the distribution of data and sharing network devices, such as printers. The LAN contrasts the wide area network (WAN), which not only covers a larger geographic distance, but also generally involves Leased line, leased telecommunication circuits or Internet links. An even greater contrast is the Internet, which is a system of globally connected business and personal computers. Ethernet and Wi-Fi are the two most common technologies used for local area networks; historical network technologies include ARCNET, Token Ring, and LocalTalk. Cabling Most wired network infrastructures utilize Category 5 cable, Category 5 or Category 6 cable, Category 6 twisted pair cabling with RJ45 (telecommunications), RJ45 compatible terminations. This medium provides physical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Embedded Software
Embedded software is computer software, written to control machines or devices that are not typically thought of as computers, commonly known as embedded systems. It is typically specialized for the particular hardware that it runs on and has time and memory constraints. This term is sometimes used interchangeably with firmware. A precise and stable characteristic feature is that no or not all functions of embedded software are initiated/controlled via a human interface, but through machine-interfaces instead. Manufacturers build embedded software into the electronics of cars, telephones, modems, robots, appliances, toys, security systems, pacemakers, televisions and set-top boxes, and digital watches, for example. This software can be very simple, such as lighting controls running on an 8-bit microcontroller with a few kilobytes of memory with the suitable level of processing complexity determined with a Probably Approximately Correct Computation framework (a methodology ...
