Hacker (computer security)

Hacker (computer security)
Bruce Sterling traces part of the roots of the computer underground to the Yippies, a 1960s counterculture movement which published the Technological Assistance Program (TAP) newsletter.[citation needed] TAP was a phone phreaking newsletter that taught techniques for unauthorized exploration of the phone network. Many people from the phreaking community are also active in the hacking community even today, and vice versa. Several subgroups of the computer underground with different attitudes use different terms to demarcate themselves from each other, or try to exclude some specific group with which they do not agree. According to Ralph D. A grey hat hacker is a combination of a black hat and a white hat hacker. A neophyte, "n00b", or "newbie" is someone who is new to hacking or phreaking and has almost no knowledge or experience of the workings of technology and hacking.[10] Intelligence agencies and cyberwarfare operatives of nation states.[17] Vulnerability scanner Password cracking

2600: The Hacker Quarterly Data mining Data mining is the process of discovering patterns in large data sets involving methods at the intersection of machine learning, statistics, and database systems.[1] Data mining is an interdisciplinary subfield of computer science and statistics with an overall goal to extract information (with intelligent methods) from a data set and transform the information into a comprehensible structure for further use.[1][2][3][4] Data mining is the analysis step of the "knowledge discovery in databases" process or KDD.[5] Aside from the raw analysis step, it also involves database and data management aspects, data pre-processing, model and inference considerations, interestingness metrics, complexity considerations, post-processing of discovered structures, visualization, and online updating.[1] Etymology[edit] In the 1960s, statisticians and economists used terms like data fishing or data dredging to refer to what they considered the bad practice of analyzing data without an a-priori hypothesis.

White hat One of the first instances of an ethical hack being used was a "security evaluation" conducted by the United States Air Force of the Multics operating systems for "potential use as a two-level (secret/top secret) system." Their evaluation found that while Multics was "significantly better than other conventional systems,"[citation needed] it also had "... vulnerabilities in hardware security, software security and procedural security"[citation needed] that could be uncovered with "a relatively low level of effort."[citation needed] The authors performed their tests under a guideline of realism, so that their results would accurately represent the kinds of access that an intruder could potentially achieve. While penetration testing concentrates on attacking software and computer systems from the start – scanning ports, examining known defects and patch installations, for example – ethical hacking, which will likely include such things, is under no such limitations. Ethical Hacking

Anonymous (group) Anonymous (used as a mass noun) is a loosely associated international network of activist and hacktivist entities. A website nominally associated with the group describes it as "an internet gathering" with "a very loose and decentralized command structure that operates on ideas rather than directives". The group became known for a series of well-publicized publicity stunts and distributed denial-of-service (DDoS) attacks on government, religious, and corporate websites. Anonymous originated in 2003 on the imageboard 4chan, representing the concept of many online and offline community users simultaneously existing as an anarchic, digitized global brain.[3][4] Anonymous members (known as "Anons") can be distinguished in public by the wearing of stylised Guy Fawkes masks.[5] In its early form, the concept was adopted by a decentralized online community acting anonymously in a coordinated manner, usually toward a loosely self-agreed goal, and primarily focused on entertainment, or "lulz".

How To Understand Programs for Password Hacking | How To Do Things Password hacking may sound like an ominous thing to most people, who also believe that someone who may know how to do it can't possibly be up to any good. On the contrary, it can actually be most useful for you or potential clients. You wouldn't know when you would need to hack your own email account in case you forgot your password, or an important client needs your help to crack a program password. Dictionary attacks. Password hacking is still a skill that not everyone can do. Research and development Cycle of research and development The research and development (R&D, also called research and technical development or research and technological development, RTD in Europe) is a specific group of activities within a business. The activities that are classified as R&D differ from company to company, but there are two primary models. In one model, the primary function of an R&D group is to develop new products; in the other model, the primary function of an R&D group is to discover and create new knowledge about scientific and technological topics for the purpose of uncovering and enabling development of valuable new products, processes, and services. Under both models, R&D differs from the vast majority of a company's activities which are intended to yield nearly immediate profit or immediate improvements in operations and involve little uncertainty as to the return on investment (ROI). Background[edit] Business[edit] Present-day R&D is a core part of the modern business world.

Australian spies buying computer bugs David Sancho, from Trend Micro, says buying bugs from reseachers encourages them to find more. Photo: Alex Schelbert The Australian government is buying computer security weaknesses found by hackers before they are sold on the black market, as part of its defence strategy, claim those at the coal face of cyber security. "The Australian government has developed these capabilities as part of ASIO, DSD [Defence Signals Directorate], CSOC [Cyber Security Operations Centre] and possibly others. He says while the government won't admit it, buying vulnerabilities is an obvious part of "gathering intelligence". Trading in vulnerabilities is a moot point in technology circles. Advertisement "There is a trade in weaponised exploits being provided by hackers to the security vendors," confirms another source, a hacker, who spoke to Fairfax's IT Pro on the condition of anonymity. "These exploits are then sold on to governments after being packaged into one of the many exploitation frameworks."

Chaos Computer Club 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 right to communication. Supporting the principles of the hacker ethic, the club also fights for free universal access to computers and technological infrastructure.[2] History[edit] The CCC was founded in Berlin on September 12, 1981 at a table which had previously belonged to the Kommune 1 in the rooms of the newspaper die tageszeitung by Wau Holland and others in anticipation of the prominent role that information technology would play in the way people live and communicate. The CCC became world famous when they drew public attention to the security flaws of the German Bildschirmtext computer network by causing it to debit DM 134,000 in a Hamburg bank in favor of the club.

Welcome to | Penetration test A penetration test , occasionally pentest , is a method of evaluating the computer security of a computer system or network by simulating an attack from external threats and internal threats. [ 1 ] The process involves an active analysis of the system for any potential vulnerabilities that could result from poor or improper system configuration, both known and unknown hardware or software flaws, or operational weaknesses in process or technical countermeasures. [ citation needed ] This analysis is carried out from the position of a potential attacker and can involve active exploitation of security vulnerabilities. [ citation needed ] Security issues uncovered through the penetration test are presented to the system's owner. [ citation needed ] Effective penetration tests will couple this information with an accurate assessment of the potential impacts to the organization and outline a range of technical and procedural countermeasures to reduce risks.
