MalwareTech
Marcus Hutchins (born 1994), also known online as MalwareTech, is a British computer security researcher known for stopping the WannaCry ransomware attack. He is employed by cybersecurity firm Kryptos Logic. Hutchins is from Ilfracombe in Devon. Early life Hutchins is the elder son of Janet Hutchins, a Scottish nurse, and Desmond Hutchins, a Jamaican social worker. Around 2003, when Hutchins was nine years old, the parents moved the family from urban Bracknell, near London, to rural Devon. Hutchins had shown early aptitude with computers and learned simple hacking skills early on such as bypassing security on school computers to install video game software. In addition, he spent time learning to be a surf lifeguard. He became involved with an online forum that promoted malware development, more as a means to show off their skills to each other rather than for nefarious purposes. When he was about 14 years old, he created his own contribution, a password stealer based on Inter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WannaCry
The WannaCry ransomware attack was a worldwide cyberattack in May 2017 by the WannaCry ransomware cryptoworm, which targeted computers running the Microsoft Windows operating system by encrypting data and demanding ransom payments in the Bitcoin cryptocurrency. It propagated by using EternalBlue, an exploit developed by the United States National Security Agency (NSA) for Windows systems. EternalBlue was stolen and leaked by a group called The Shadow Brokers a month prior to the attack. While Microsoft had released patches previously to close the exploit, much of WannaCry's spread was from organizations that had not applied these, or were using older Windows systems that were past their end-of-life. These patches were imperative to organizations' cyber security but many were not implemented due to ignorance of their importance. Some have claimed a need for 24/7 operation, aversion to risking having formerly working applications breaking because of patch changes, lack of pers ...

Kronos (malware)
Kronos was a type of banking malware first reported in 2014. It was sold for $7,000. It was developed as a followup to the UPAS Kit which has been released in 2012. Similar to Zeus, it was focused on stealing banking login credentials from browser sessions via a combination of keylogging and web injection. In 2015, its attacks were focused on British banks. In August 2017, British security researcher Marcus Hutchins (aka 'MalwareTech'), previously notable for his involvement stopping the May 2017 WannaCry ransomware attack, was arrested by the FBI whilst visiting the United States. He was alleged to have created the software in 2014, and to have sold it in 2015 via the AlphaBay forums. Hutchins later admitted to being paid to work on Kronos and its predecessor UPAS Kit (named after the toxic Upas tree ''Antiaris toxicaria'' is a tree in the mulberry and fig family, Moraceae.

Bracknell
Bracknell () is a large town and civil parish in Berkshire, England, the westernmost area within the Greater London Urban Area and the administrative centre of the Borough of Bracknell Forest. It lies to the east of Reading, south of Maidenhead, southwest of Windsor and west of central London. Originally a market village and part of the Windsor Great Forest, Bracknell experienced a period of huge growth during the mid-20th century when it was declared a new town.

Dark Web
The dark web is the World Wide Web content that exists on '' darknets'': overlay networks that use the Internet but require specific software, configurations, or authorization to access. Through the dark web, private computer networks can communicate and conduct business anonymously without divulging identifying information, such as a user's location. The dark web forms a small part of the deep web, the part of the Web not indexed by web search engines, although sometimes the term ''deep web'' is mistakenly used to refer specifically to the dark web. The darknets which constitute the dark web include small, friend-to-friend peer-to-peer networks, as well as large, popular networks such as Tor, Freenet, I2P, and Riffle operated by public organizations and individuals. Users of the dark web refer to the regular web as Clearnet due to its unencrypted nature. The Tor dark web or onionland uses the traffic anonymization technique of onion routing under the network's top-level ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mirai (malware)
Mirai (from the Japanese word for "future", 未来) is a malware that turns networked devices running Linux into remotely controlled bots that can be used as part of a botnet in large-scale network attacks. It primarily targets online consumer devices such as IP cameras and home routers. The Mirai botnet was first found in August 2016 by MalwareMustDie, a white hat malware research group, and has been used in some of the largest and most disruptive distributed denial of service (DDoS) attacks, including an attack on 20 September 2016 on computer security journalist Brian Krebs' website, an attack on French web host OVH, and the October 2016 Dyn cyberattack. According to a chat log between Anna-senpai and Robert Coelho, Mirai was named after the 2011 TV anime series '' Mirai Nikki''. The software was initially used by the creators to DDoS ''Minecraft'' servers and companies offering DDoS protection to ''Minecraft'' servers, with the authors using Mirai to operate a prote ...

Necurs Botnet
The Necurs botnet is a distributor of many pieces of malware, most notably Locky. Reports Around June 1, 2016, the botnet went offline, perhaps due to a glitch in the Command and control (malware), command and control server running Necurs. However, three weeks later, Jon French from AppRiver discovered a spike in spam emails, signifying either a temporary spike in the botnet's activity or return to its normal pre-June 1 state. In a 2020 report, it was noted to have particularly targeted India, Southeast Asia, Turkey and Mexico. Distributed malware * Bart * Dridex * Locky Locky is ransomware malware released in 2016.

Kelihos Botnet
The Kelihos botnet, also known as Hlux, is a botnet mainly involved in spamming and the theft of bitcoins. History The Kelihos botnet was first discovered around . Researchers originally suspected having found a new version of either the Storm or Waledac botnet, due to similarities in the modus operandi and source code of the bot, but analysis of the botnet showed it was instead a new, 45,000- infected-computer-strong, botnet that was capable of sending an estimated spam messages a day. In Microsoft took down the botnet in an operation codenamed "Operation b79". At the same time, Microsoft filed civil charges against Dominique Alexander Piatti, dotFREE Group SRO and 22 John Doe defendants for suspected involvement in the botnet for issuing 3,700 subdomains that were used by the botnet. These charges were later dropped when Microsoft determined that the named defendants did not intentionally aid the botnet controllers. In January 2012 a new version of the botnet was discovered ...

Blog
A blog (a truncation of "weblog") is a discussion or informational website published on the World Wide Web consisting of discrete, often informal diary-style text entries (posts). Posts are typically displayed in reverse chronological order so that the most recent post appears first, at the top of the web page. Until 2009, blogs were usually the work of a single individual, occasionally of a small group, and often covered a single subject or topic. In the 2010s, "multi-author blogs" (MABs) emerged, featuring the writing of multiple authors and sometimes professionally edited. MABs from newspapers, other media outlets, universities, think tanks, advocacy groups, and similar institutions account for an increasing quantity of blog traffic. The rise of Twitter and other " microblogging" systems helps integrate MABs and single-author blogs into the news media. ''Blog'' can also be used as a verb, meaning ''to maintain or add content to a blog''. The emergence and growth of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cold Turkey
"Cold turkey" refers to the abrupt cessation of a substance dependence and the resulting unpleasant experience, as opposed to gradually easing the process through reduction over time or by using replacement medication. Sudden withdrawal from drugs such as alcohol, benzodiazepines, and barbiturates can be extremely dangerous, leading to potentially fatal seizures. For long-term alcoholics, going cold turkey can cause life-threatening delirium tremens, rendering this an inappropriate method for breaking an alcohol addiction. In the case of opioid withdrawal, going "cold turkey" is extremely unpleasant but less dangerous.Opiate withdrawal Medline Plus — NIH. Life-threatening issues are unlikely unless one has a pre-existing medical condition. |
Drug Addiction
Addiction is a neuropsychological disorder characterized by a persistent and intense urge to engage in certain behaviors, one of which is the usage of a drug, despite substantial harm and other negative consequences. Repetitive drug use often alters brain function in ways that perpetuate craving, and weakens (but does not completely negate) self-control. This phenomenon – drugs reshaping brain function – has led to an understanding of addiction as a brain disorder with a complex variety of psychosocial as well as neurobiological (and thus involuntary) factors that are implicated in addiction's development. Classic signs of addiction include compulsive engagement in rewarding stimuli, ''preoccupation'' with substances or behavior, and continued use despite negative consequences. Habits and patterns associated with addiction are typically characterized by immediate gratification (short-term reward), coupled with delayed deleterious effects (long-term costs). Exam ...

Higher Education
Higher education is tertiary education leading to award of an academic degree. Higher education, also called post-secondary education, third-level or tertiary education, is an optional final stage of formal learning that occurs after completion of secondary education. It represents levels 6, 7 and 8 of the 2011 version of the International Standard Classification of Education structure. Tertiary education at a non-degree level is sometimes referred to as further education or continuing education as distinct from higher education. The right of access to higher education The right of access to higher education is mentioned in a number of international human rights instruments. The UN International Covenant on Economic, Social and Cultural Rights of 1966 declares, in Article 13, that "higher education shall be made equally accessible to all, on the basis of capacity, by every appropriate means, and in particular by the progressive introduction of free education".
