Trojan (malware)
In computing, a trojan horse (or simply trojan; often capitalized, but see below) is a kind of malware that misleads users as to its true intent by disguising itself as a normal program. Trojans are generally spread by some form of social engineering. For example, a user may be duped into executing an email attachment disguised to appear innocuous (e.g., a routine form to be filled in), or into clicking on a fake advertisement on the Internet. Although their payload can be anything, many modern forms act as a backdoor, contacting a controller who can then have unauthorized access to the affected device. Ransomware attacks are often carried out using a trojan. Unlike computer viruses and worms, trojans generally do not attempt to inject themselves into other files or otherwise propagate themselves. Origins of the term The term is derived from the ancient Greek story of the deceptive Trojan Horse that led to the fall of the city of Troy. It is unclear where and when the comput ...

Computing
Computing is any goal-oriented activity requiring, benefiting from, or creating computer, computing machinery. It includes the study and experimentation of algorithmic processes, and the development of both computer hardware, hardware and software. Computing has scientific, engineering, mathematical, technological, and social aspects. Major computing disciplines include computer engineering, computer science, cybersecurity, data science, information systems, information technology, and software engineering. The term ''computing'' is also synonymous with counting and calculation, calculating. In earlier times, it was used in reference to the action performed by Mechanical computer, mechanical computing machines, and before that, to Computer (occupation), human computers. History The history of computing is longer than the history of computing hardware and includes the history of methods intended for pen and paper (or for chalk and slate) with or without the aid of tables. ...

Botnet
A botnet is a group of Internet-connected devices, each of which runs one or more Internet bot, bots. Botnets can be used to perform distributed denial-of-service attack, distributed denial-of-service (DDoS) attacks, steal data, send Spamming, spam, and allow the attacker to access the device and its connection. The owner can control the botnet using command and control (C&C) software. The word "botnet" is a portmanteau of the words "robot" and "Computer network, network". The term is usually used with a negative or malicious connotation. Overview A botnet is a logical collection of Internet-connected devices, such as computers, smartphones or Internet of things (IoT) devices whose Computer security, security have been breached and control ceded to a third party. Each compromised device, known as a "bot," is created when a device is penetrated by software from a ''malware'' (malicious software) distribution. The controller of a botnet is able to direct the activities of these comp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chaos Computer Club
The Chaos Computer Club (CCC) is Europe's largest association of Hacker (computer security), hackers with 7,700 registered members. Founded in 1981, the association is incorporated as an ''eingetragener Verein'' in Germany, with local chapters (called ''Erfa-Kreise'') in various cities in Germany and the surrounding countries, particularly where there are German-speaking communities. Since 1985, some chapters in Switzerland have organized an independent sister association called the (CCC-CH) instead. The CCC describes itself as "a galactic community of life forms, independent of age, sex, race or societal orientation, which strives across borders for freedom of information…". In general, the CCC advocates more transparency in government, freedom of information, and the human rights, human right to communication.

ANOM
Operation Trojan Shield (stylized TRØJAN SHIELD), part of Operation Ironside, was a collaboration by law enforcement agency, law enforcement agencies from several countries, running between 2018 and 2021. It was a sting operation that intercepted millions of messages sent through the supposedly secure smartphone-based Proprietary software, proprietary messaging app ANOM (also stylized as AN0M or ΛNØM). The ANOM service was widely used by criminals, but instead of providing secure communication, it was actually a trojan horse (computing), trojan horse covertly distributed by the United States Federal Bureau of Investigation (FBI) and the Australian Federal Police (AFP), enabling them to monitor all communications. Through collaboration with other law enforcement agencies worldwide, the operation resulted in the arrest of over 800 suspects allegedly involved in criminal activity in 16 countries. Among the arrested people were alleged members of Australian-based Italian mafia, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supply Chain Attack
A supply chain attack is a cyber-attack that seeks to damage an organization by targeting less secure elements in the supply chain. A supply chain attack can occur in any industry, from the financial sector, oil industry, to a government sector. A supply chain attack can happen in software or hardware. Cybercriminals typically tamper with the manufacturing or distribution of a product by installing malware or hardware-based spying components. Broadcom#Symantec_enterprise_security, Symantec's 2019 Internet Security Threat Report states that supply chain attacks increased by 78 percent in 2018. A supply chain is a system of activities involved in handling, distributing, manufacturing, and processing goods in order to move resources from a vendor into the hands of the final consumer. A supply chain is a complex network of interconnected players governed by supply and demand. Although supply chain attack is a broad term without a universally agreed upon definition, in reference to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Typosquatting
Typosquatting, also called URL hijacking, a sting site, a cousin domain, 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. A user accidentally entering an incorrect website address may be led to any URL, including an alternative website owned by a cybersquatter. The typosquatter's URL will usually be ''similar'' to the victim's site address; the typosquatting site could be in the form of: *A 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 (e.g., .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 doma ...

Sudo
() is a shell (computing), shell command (computing), command on Unix-like operating systems that enables a user to run a program with the security privileges of another user, by default the superuser. It originally stood for "superuser do", as that was all it did, and this remains its most common usage; however, the official Sudo project page lists it as "su 'do. The current Linux manual pages define as "substitute user", making the correct meaning of "substitute user, do", because can run a command as other users as well. Unlike the similar command Su (Unix), su, users must, by default, supply their own password for authentication, rather than the password of the target user. After authentication, and if the configuration file (typically #Configuration, /etc/sudoers) permits the user access, the system invokes the requested command. The configuration file offers detailed access permissions, including enabling commands only from the invoking terminal; requiring a password p ...

Computer Program
A computer program is a sequence or set of instructions in a programming language for a computer to Execution (computing), execute. It is one component of software, which also includes software documentation, documentation and other intangible components. A ''computer program'' in its human-readable form is called source code. Source code needs another computer program to Execution (computing), execute because computers can only execute their native machine instructions. Therefore, source code may be Translator (computing), translated to machine instructions using a compiler written for the language. (Assembly language programs are translated using an Assembler (computing), assembler.) The resulting file is called an executable. Alternatively, source code may execute within an interpreter (computing), interpreter written for the language. If the executable is requested for execution, then the operating system Loader (computing), loads it into Random-access memory, memory and ...

Cloud Computing
Cloud computing is "a paradigm for enabling network access to a scalable and elastic pool of shareable physical or virtual resources with self-service provisioning and administration on-demand," according to International Organization for Standardization, ISO. Essential characteristics In 2011, the National Institute of Standards and Technology (NIST) identified five "essential characteristics" for cloud systems. Below are the exact definitions according to NIST: * On-demand self-service: "A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service provider." * Broad network access: "Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, tablets, laptops, and workstations)." * Pooling (resource management), Resource pooling: " The provider' ...
