Spear Phishing
Phishing is a type of Social engineering (security), social engineering where an attacker sends a fraudulent (e.g., spoofed, fake, or otherwise deceptive) message designed to trick a person into revealing sensitive information to the attacker or to deploy malicious software on the victim's infrastructure like ransomware. Phishing attacks have become increasingly sophisticated and often transparently mirror the site being targeted, allowing the attacker to observe everything while the victim is navigating the site, and transverse any additional security boundaries with the victim. As of 2020, phishing is by far the most common attack performed by cybercriminals, the FBI's Internet Crime Complaint Center, Internet Crime Complaint Centre recording over twice as many incidents of phishing than any other type of computer crime. The first recorded use of the term "phishing" was in the Security hacker#Cracker, cracking toolkit AOHell created by Koceilah Rekouche in 1995; however, it i ...

Voice Over IP
Voice over Internet Protocol (VoIP), also called IP telephony, is a method and group of technologies for the delivery of speech, voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. The terms Internet telephony, broadband telephony, and broadband phone service specifically refer to the provisioning of communications services (voice, fax, Short Message Service, SMS, voice-messaging) over the Internet, rather than via the public switched telephone network (PSTN), also known as plain old telephone service (POTS). Overview The steps and principles involved in originating VoIP telephone calls are similar to traditional digital telephony and involve signaling, channel setup, digitization of the analog voice signals, and encoding. Instead of being transmitted over a circuit-switched network, the digital information is packetized and transmission occurs as IP packets over a packet-switched network. They transport media streams using spec ...

Pointer (user Interface)
In human–computer interaction, a cursor is an indicator used to show the current position on a computer monitor or other display device that will respond to input from a text input or pointing device. The mouse cursor is also called a pointer, owing to its resemblance in usage to a pointing stick. Etymology ''Cursor'' is Latin for 'runner'. A cursor is a name given to the transparent slide engraved with a hairline used to mark a point on a slide rule. The term was then transferred to computers through analogy. On 14 November 1963, while attending a conference on computer graphics in Reno, Nevada, Douglas Engelbart of Augmentation Research Center (ARC) first expressed his thoughts to pursue his objective of developing both hardware and software computer technology to "augment" human intelligence by pondering how to adapt the underlying principles of the planimeter to inputting X- and Y-coordinate data, and envisioned something like the cursor of a mouse he initially called ...

Subdomain
In the Domain Name System (DNS) hierarchy, a subdomain is a domain that is a part of another (main) domain. For example, if a domain offered an online store as part of their website example.com, it might use the subdomain shop.example.com . Overview The Domain Name System (DNS) has a tree structure or hierarchy, which includes nodes on the tree being a domain name. A subdomain is a domain that is part of a larger domain. Each label may contain from 1 to 63 octets. The full domain name may not exceed a total length of 253 ASCII characters in its textual representation.RFC 1035, ''Domain names--Implementation and specification'', P. Mockapetris (Nov 1987) Subdomains are defined by editing the DNS zone file pertaining to the parent domain. However, there is an ongoing debate over the use of the term "subdomain" when referring to names which map to the Address record A (host) and various other types of zone records which may map to any public IP address destination and any type ...

Typosquatting
Typosquatting, also called URL hijacking, a sting site, or a fake URL, is a form of cybersquatting, and possibly brandjacking which relies on mistakes such as typos made by Internet users when inputting a website address into a web browser. Should a user accidentally enter an incorrect website address, they may be led to any URL (including an alternative website owned by a cybersquatter). The typosquatter's URL will usually be one of five kinds, all ''similar to'' the victim site address: *A common misspelling, or foreign language spelling, of the intended site *A misspelling based on a typographical error *A plural of a singular domain name *A different top-level domain: (i.e. .com instead of .org) *An abuse of the Country Code Top-Level Domain (ccTLD) (.cm, .co, or .om instead of .com) Similar abuses: *Combosquatting - no misspelling, but appending an arbitrary word that appears legitimate, but that anyone could register. *Doppelganger domain - omitting a period or inserting ...

Uniform Resource Locator
A Uniform Resource Locator (URL), colloquially termed as a web address, is a reference to a web resource that specifies its location on a computer network and a mechanism for retrieving it. A URL is a specific type of Uniform Resource Identifier (URI), although many people use the two terms interchangeably. URLs occur most commonly to reference web pages (HTTP) but are also used for file transfer (FTP), email (mailto), database access (JDBC), and many other applications. Most web browsers display the URL of a web page above the page in an address bar. A typical URL could have the form http://www.example.com/index.html, which indicates a protocol (http), a hostname (www.example.com), and a file name (index.html). History Uniform Resource Locators were defined in in 1994 by Tim Berners-Lee, the inventor of the World Wide Web, and the URI working group of the Internet Engineering Task Force (IETF), as an outcome of collaboration started at the IETF Living Documents birds of a ...

Watering Hole Attack
Watering hole is a computer attack strategy in which an attacker guesses or observes which websites an organization often uses and infects one or more of them with malware. Eventually, some member of the targeted group will become infected. Hacks looking for specific information may only attack users coming from a specific IP address. This also makes the hacks harder to detect and research.Symantec. Internet Security Threat Report, April 2016, p. 38 https://www.symantec.com/content/dam/symantec/docs/reports/istr-21-2016-en.pdf The name is derived from predators in the natural world, who wait for an opportunity to attack their prey near watering holes. Defense techniques Websites are often infected through zero-day vulnerabilities on browsers or other software. A defense against known vulnerabilities is to apply the latest software patches to remove the vulnerability that allowed the site to be infected. This is assisted by users to ensure that all of their software is running ...

Framing (World Wide Web)
In the context of a web browser, a frame is a part of a web page or browser window which displays content independent of its container, with the ability to load content independently. The HTML or media elements shown in a frame may come from a different web site as the other elements of content on display, although this practice, known as framing, is today often regarded as a violation of same-origin policy. In HTML, a frameset is a group of named frames to which web pages and media can be directed; an iframe provides for a frame to be placed inside the body of a document. Since the early 2000s, the use of framesets has been considered obsolete due to usability and accessibility concerns, and the feature has been removed from the HTML5 standard. Tags and attributes The frames in HTML are created using the tag pair. The tag is a container tag for all other tags that are used to create frames. The tag replaces the tag in frameset documents.The tag defines how to divide t ...

MPack (software)
In computer security, MPack is a PHP-based malware kit produced by Russian crackers. The first version was released in December 2006. Since then a new version is thought to have been released roughly every month. It is thought to have been used to infect up to 160,000 PCs with keylogging software. In August 2007 it was believed to have been used in an attack on the web site of the Bank of India which originated from the Russian Business Network. Unusual for such kits, MPack is sold as commercial software (costing $500 to $1,000 US), and is provided by its developers with technical support and regular updates of the software vulnerabilities it exploits. Modules are sold by the developers containing new exploits. These cost between $50 and $150 US depending on how severe the exploit is. The developers also charge to make the scripts and executables undetectable by antivirus software. The server-side software in the kit is able to customize attacks to a variety of web browser ...

Cross-site Scripting
Cross-site scripting (XSS) is a type of security vulnerability that can be found in some web applications. XSS attacks enable attackers to inject client-side scripts into web pages viewed by other users. A cross-site scripting vulnerability may be used by attackers to bypass access controls such as the same-origin policy. Cross-site scripting carried out on websites accounted for roughly 84% of all security vulnerabilities documented by Symantec up until 2007.During the second half of 2007, 11,253 site-specific cross-site vulnerabilities were documented by XSSed, compared to 2,134 "traditional" vulnerabilities documented by Symantec, in XSS effects vary in range from petty nuisance to significant security risk, depending on the sensitivity of the data handled by the vulnerable site and the nature of any security mitigation implemented by the site's owner network. Background Security on the web depends on a variety of mechanisms, including an underlying concept of trust know ...

Exploit Kit
An exploit kit is a tool used for automatically managing and deploying exploits against a target computer. Exploit kits allow attackers to deliver malware without having advanced knowledge of the exploits being used. Browser exploits are typically used, although they may also include exploits targeting common software, such as Adobe Reader, or the operating system itself. Most kits are written in PHP. Exploit kits are often sold on the black market, both as standalone kits, and as a service. History Some of the first exploit kits were WebAttacker and MPack, both created in 2006. They were sold on black markets, enabling attackers to use exploits without advanced knowledge of computer security. The Blackhole exploit kit was released in 2010, and could either be purchased outright, or rented for a fee. Malwarebytes stated that Blackhole was the primary method of delivering malware in 2012 and much of 2013. After the arrest of the authors in late 2013, use of the kit sharply ...
