Internet activism, hacktivism, or hactivism, is the use of computer-based techniques such as hacking as a form of civil disobedience to promote a political agenda or social change. With roots in hacker culture and hacker ethics, its ends are often related to free speech, human rights, or freedom of information movements.

Kleptography is the study of stealing information securely and subliminally. The term was introduced by Adam Young and Moti Yung in the Proceedings of Advances in Cryptology – Crypto '96. Kleptography is a subfield of cryptovirology and is a natural extension of the theory of subliminal channels that was pioneered by Gus Simmons while at Sandia National Laboratory. A kleptographic backdoor is synonymously referred to as an asymmetric backdoor. Kleptography encompasses secure and covert communications through cryptosystems and cryptographic protocols. This is reminiscent of, but not the same as steganography that studies covert communications through graphics, video, digital audio data, and so forth.
SSLeay is an open-source SSL implementation. It was developed by Eric Andrew Young and Tim J. Hudson as an SSL 3.0 implementation using RC2 and RC4 encryption. The recommended pronunciation is to say each letter s-s-l-e-a-y and was first developed by Eric A. Young ("eay"). SSLeay also included an implementation of the DES from earlier work by Eric Young which was believed to be the first open-source implementation of DES. Development of SSLeay unofficially mostly ended, and volunteers forked the project under the OpenSSL banner around December 1998, when Hudson and Young both commenced working for RSA Security in Australia.
The Joint Worldwide Intelligence Communication System is the United States Department of Defense's secure intranet system that houses top secret and sensitive compartmented information.

Apache Taverna was an open source software tool for designing and executing workflows, initially created by the myGrid project under the name Taverna Workbench, then a project under the Apache incubator. Taverna allowed users to integrate many different software components, including WSDL SOAP or REST Web services, such as those provided by the National Center for Biotechnology Information, the European Bioinformatics Institute, the DNA Databank of Japan (DDBJ), SoapLab, BioMOBY and EMBOSS. The set of available services was not finite and users could import new service descriptions into the Taverna Workbench.
A Sybil attack is a type of attack on a computer network service in which an attacker subverts the service's reputation system by creating a large number of pseudonymous identities and uses them to gain a disproportionately large influence. It is named after the subject of the book Sybil, a case study of a woman diagnosed with dissociative identity disorder. The name was suggested in or before 2002 by Brian Zill at Microsoft Research. The term pseudospoofing had previously been coined by L. Detweiler on the Cypherpunks mailing list and used in the literature on peer-to-peer systems for the same class of attacks prior to 2002, but this term did not gain as much influence as "Sybil attack".
WikiLeaks is a media organisation and publisher of leaked documents. It is a non-profit and is funded by donations and media partnerships. It has published classified documents and other media provided by anonymous sources. It was founded in 2006 by Julian Assange, an Australian editor, publisher, and activist, who is currently challenging extradition to the United States over his work with WikiLeaks. Since September 2018, Kristinn Hrafnsson has served as its editor-in-chief. Its website states that it has released more than ten million documents and associated analyses. WikiLeaks' most recent publication of original documents was in 2019 and its most recent publication was in 2021. From November 2022, numerous documents on the organisation's website became inaccessible. In 2023, Assange said that WikiLeaks is no longer able to publish due to his imprisonment and the effect that US government surveillance and WikiLeaks' funding restrictions were having on potential whistleblowers.
A decision stump is a machine learning model consisting of a one-level decision tree. That is, it is a decision tree with one internal node which is immediately connected to the terminal nodes. A decision stump makes a prediction based on the value of just a single input feature. Sometimes they are also called 1-rules.

On July 12, 2007, a series of air-to-ground attacks were conducted by a team of two U.S. AH-64 Apache helicopters in Al-Amin al-Thaniyah, New Baghdad, during the Iraqi insurgency which followed the invasion of Iraq. On April 5, 2010, the attacks received worldwide coverage and controversy following the release of 39 minutes of classified gunsight footage by WikiLeaks. The video, which WikiLeaks titled Collateral Murder, showed the crew firing on a group of people and killing several of them, including two Reuters journalists, and then laughing at some of the casualties, all of whom were civilians. An anonymous U.S. military official confirmed the authenticity of the footage, which provoked global discussion on the legality and morality of the attacks.
