Dexter (malware)
Dexter is a computer virus or Point-of-sale malware, point of sale (PoS) malware which infects computers running Microsoft Windows and was discovered by IT security firm Seculert, in December 2012. It infects Point of sale, PoS systems worldwide and steals sensitive information such as credit and debit card information. Function When Dexter infects a machine it injects itself into iexplore.exe, the Executable, executable file that runs Internet Explorer. It also changes Windows Registry, Windows registry entries to allow the malware to run on startup of the machine. The malware parses memory dumps by using a Windows function called ReadProcessMemory. Dexter uploads the contents of the memory it parses from PoS machines to a server located in the Seychelles. The information Dexter can collect includes credit and debit card information, user names and host names, operating system data, a list of running processes, and Key (cryptography), encryption keys so the data it collects can ...

Computer Virus
A computer virus is a type of malware that, when executed, replicates itself by modifying other computer programs and Code injection, inserting its own Computer language, code into those programs. If this replication succeeds, the affected areas are then said to be "infected" with a computer virus, a metaphor derived from biological viruses. Computer viruses generally require a Computer program, host program. The virus writes its own code into the host program. When the program runs, the written virus program is executed first, causing infection and damage. By contrast, a computer worm does not need a host program, as it is an independent program or code chunk. Therefore, it is not restricted by the Computer program, host program, but can run independently and actively carry out attacks. Virus writers use social engineering (security), social engineering deceptions and exploit detailed knowledge of vulnerability (computing), security vulnerabilities to initially infect systems an ...

Cyberwarfare
Cyberwarfare is the use of cyberattack, cyber attacks against an enemy State (polity), state, causing comparable harm to actual warfare and/or disrupting vital computer systems. Some intended outcomes could be espionage, sabotage, propaganda, Internet manipulation, manipulation or economic warfare. There is significant debate among experts regarding the definition of cyberwarfare, and even if such a thing exists. One view is that the term is a misnomer since no cyber attacks to date could be described as a war. An alternative view is that it is a suitable label for cyber attacks which cause physical damage to people and objects in the real world. Many countries, including the United States, United Kingdom, Russia, China, Israel, Iran, and North Korea, have active cyber capabilities for offensive and defensive operations. As states explore the use of cyber operations and combine capabilities, the likelihood of physical confrontation and violence playing out as a result of, or p ...

2012 In Computing
1 (one, unit, unity) is a number, numeral, and glyph. It is the first and smallest positive integer of the infinite sequence of natural numbers. This fundamental property has led to its unique uses in other fields, ranging from science to sports, where it commonly denotes the first, leading, or top thing in a group. 1 is the unit of counting or measurement, a determiner for singular nouns, and a gender-neutral pronoun. Historically, the representation of 1 evolved from ancient Sumerian and Babylonian symbols to the modern Arabic numeral. In mathematics, 1 is the multiplicative identity, meaning that any number multiplied by 1 equals the same number. 1 is by convention not considered a prime number. In digital technology, 1 represents the "on" state in binary code, the foundation of computing. Philosophically, 1 symbolizes the ultimate reality or source of existence in various traditions. In mathematics The number 1 is the first natural number after 0. Each natural numb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proactive Cyber Defence
Proactive cyber defense means acting in anticipation to oppose an attack through cyber and cognitive domains. Proactive cyber defense can be understood as options between offensive and defensive measures. It includes interdicting, disrupting or deterring an attack or a threat's preparation to attack, either pre-emptively or in self-defence. Proactive cyber defense differs from active defence, in that the former is pre-emptive (does not waiting for an attack to occur). Furthermore, active cyber defense differs from offensive cyber operations (OCO) in that the latter requires legislative exceptions to undertake. Hence, offensive cyber capabilities may be developed in collaboration with industry and facilitated by private sector; these operations are often led by nation-states. Methods and aims Common methods of proactive cyber defense include cyber deception, attribution, threat hunting and adversarial pursuit. The mission of the pre-emptive and proactive operations is to conduc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Cyber Attack Threat Trends
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. D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cyber Security Standards
Information security standards (also cyber security standards) are techniques generally outlined in published materials that attempt to protect a user's or organization's cyber environment. This environment includes users themselves, networks, devices, all software, processes, information in storage or transit, applications, services, and systems that can be connected directly or indirectly to networks. The principal objective is to reduce the risks, including preventing or mitigating cyber-attacks. These published materials comprise tools, policies, security concepts, security safeguards, guidelines, risk management approaches, actions, training, best practices, assurance, and technologies. History Cybersecurity standards have existed over several decades as users and providers have collaborated in many domestic and international forums to effect the necessary capabilities, policies, and practices – generally emerging from work at the Stanford Consortium for Research on Informa ...

Antimalware
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 ...
