A hacker is a person skilled in information technology who achieves goals by non-standard means. The term has become associated in popular culture with a security hacker – someone with knowledge of bugs or exploits to break into computer systems and access data which would otherwise be inaccessible to them. In a positive connotation, though, hacking can also be utilized by legitimate figures in legal situations. For example, law enforcement agencies sometimes use hacking techniques to collect evidence on criminals and other malicious actors. This could include using anonymity tools to mask their identities online and pose as criminals.
Software cracking is an act of removing copy protection from a software. Copy protection can be removed by applying a specific crack. A crack can mean any tool that enables breaking software protection, a stolen product key, or guessed password. Cracking software generally involves circumventing licensing and usage restrictions on commercial software by illegal methods. These methods can include modifying code directly through disassembling and bit editing, sharing stolen product keys, or developing software to generate activation keys. Examples of cracks are: applying a patch or by creating reverse-engineered serial number generators known as keygens, thus bypassing software registration and payments or converting a trial/demo version of the software into fully-functioning software without paying for it. Software cracking contributes to the rise of online piracy where pirated software is distributed to end-users through filesharing sites like BitTorrent, One click hosting (OCH), or via Usenet downloads, or by downloading bundles of the original software with cracks or keygens.
L0pht Heavy Industries was a hacker collective active between 1992 and 2000 and located in the Boston, Massachusetts area. The L0pht was one of the first viable hackerspaces in the US, and a pioneer of responsible disclosure. The group famously testified in front of Congress in 1998 on the topic of ‘Weak Computer Security in Government’.
A key generator (key-gen) is a computer program that generates a product licensing key, such as a serial number, necessary to activate for use of a software application. Keygens may be legitimately distributed by software manufacturers for licensing software in commercial environments where software has been licensed in bulk for an entire site or enterprise, or they may be developed and distributed illegitimately in circumstances of copyright infringement or software piracy.
Howard Rheingold is an American critic, writer, and teacher, known for his specialties on the cultural, social and political implications of modern communication media such as the Internet, mobile telephony and virtual communities.
In cryptanalysis and computer security, password cracking is the process of guessing passwords protecting a computer system. A common approach is to repeatedly try guesses for the password and to check them against an available cryptographic hash of the password. Another type of approach is password spraying, which is often automated and occurs slowly over time in order to remain undetected, using a list of common passwords.
Out of the Inner Circle: A Hacker's Guide to Computer Security is a book by Bill Landreth and Howard Rheingold, published in 1985 by Microsoft Press and distributed by Simon & Schuster (ISBN 0-671-30942-0). The book was created to provide insight into the ways and methods of the hacking community in the days before Internet became prevalent. Although largely outdated and nostalgic, it does show what brought on many of the current trends we see in network security today.
Peiter C. Zatko, better known as Mudge, is an American network security expert, open source programmer, writer, and hacker. He was the most prominent member of the high-profile hacker think tank the L0pht as well as the computer and culture hacking cooperative the Cult of the Dead Cow.
A security hacker is someone who explores methods for breaching defenses and exploiting weaknesses in a computer system or network. Hackers may be motivated by a multitude of reasons, such as profit, protest, information gathering, challenge, recreation, or evaluation of a system weaknesses to assist in formulating defenses against potential hackers.
Crack is a Unix password cracking program designed to allow system administrators to locate users who may have weak passwords vulnerable to a dictionary attack. Crack was the first standalone password cracker for Unix systems and the first to introduce programmable dictionary generation as well.
Thomas Anderson is an American technology entrepreneur and co-founder of the social networking website Myspace, which he founded in 2003 with Chris DeWolfe.

An advanced persistent threat (APT) is a stealthy threat actor, typically a state or state-sponsored group, which gains unauthorized access to a computer network and remains undetected for an extended period. In recent times, the term may also refer to non-state-sponsored groups conducting large-scale targeted intrusions for specific goals.
Kristoffer Wilhelm von Hassel is an American boy known for being the world's youngest known hacker and notable for being the youngest "security researcher" listed on Microsoft's Security Techcenter as having exposed a security vulnerability. At the age of five, Hassel exposed security lapses in the Microsoft Live Xbox system, prompting wide media coverage, with some journalists highlighting the dropping age of hackers and their technology mastery.
CrowdStrike Holdings, Inc. is an American cybersecurity technology company based in Austin, Texas. It provides endpoint security, threat intelligence, and cyberattack response services.
EternalBlue is a computer exploit software developed by the U.S. National Security Agency (NSA). It is based on a vulnerability in Microsoft Windows that allowed users to gain access to any number of computers connected to a network. The NSA knew about this vulnerability but did not disclose it to Microsoft for several years, since they planned to use it as a defense mechanism against cyber attacks. In 2017, the NSA discovered that the software was stolen by a group of hackers known as the Shadow Brokers. Microsoft was informed of this and released security updates in March 2017 patching the vulnerability. While this was happening, the hacker group attempted to auction off the software, but did not succeed in finding a buyer. EternalBlue was then publicly released on April 14, 2017.
Cryptojacking is the act of exploiting a computer to mine cryptocurrencies, often through websites, against the user's will or while the user is unaware. One notable piece of software used for cryptojacking was Coinhive, which was used in over two-thirds of cryptojacks before its March 2019 shutdown. The cryptocurrencies mined the most often are privacy coins—coins with hidden transaction histories—such as Monero and Zcash.
