An Internet leak occurs when a party's confidential information is released to the public on the Internet. Various types of information and data can be, and have been, "leaked" to the Internet, the most common being personal information, computer software and source code, and artistic works such as books or albums. For example, a musical album is leaked if it has been made available to the public on the Internet before its official release date; and is still intended to be confidential.
Source code leaks
Source code leaks are usually caused by misconfiguration of software like CVS or FTP which allow people to get source files by exploiting, by software bugs, or by employees that have access to the sources of part of them revealing the code in order to harm the company.
There were many cases of source code leaks in the history of software development.
For instance, as Fraunhofer IIS released in 1994 only a low quality version of their MP3 encoding software (l3enc), a hacker named SoloH gathered the source code from the unprotected servers of the University of Erlangen and developed a higher quality version, which started the MP3 revolution on the internet.
In 2003 a hacker exploited a security hole in Microsoft's Outlook to get the complete source of the video game Half-Life 2, which was under development at the time. The complete source was soon available in various file sharing networks. This leak was rumored to be the cause of the game's delay, but later was stated not to be.
Also in 2003, source code to Diebold Election Systems Inc. voting machines was leaked. Researchers at Johns Hopkins University and Rice University published a damning critique of Diebold's products, based on an analysis of the software. They found, for example, that it would be easy to program a counterfeit voting card to work with the machines and then use it to cast multiple votes inside the voting booth.
In 2004, a large portion of Windows NT 4.0's source code and a small percentage (reportedly about 15%) of Windows 2000's were leaked online. The Windows 2000 source code leak was analysed by a writer for (now defunct) website Kuro5hin who noted that while the code was generally well written, allegedly "there are a dozen or so 'fucks' and 'shits', and hundreds of 'craps'." The writer also noted that there were a lot of code hacks, with the "uglier" ones mostly being for compatibility with older programs and some hardware. It was feared that because of the leak, the number of security exploits would increase due to wider scrutiny of the source code. It was later discovered that the source of the leak originated from Mainsoft.
Also in 2004, partial (800 MB) proprietary source code that drives Cisco Systems' networking hardware was made available in the internet. The site posted two files of source code written in the C programming language, which apparently enables some next-generation IPv6 functionality. News of the latest source code leak appeared on a Russian security site.
In 2006, Anonymous hackers stole source code (about 1 GiB) for Symantec's pcAnywhere from the company's network. While confirmed in January 2012, it is still unclear how the hackers accessed the network.
In January 2011 the "stolen source code" of Kaspersky Anti-Virus 2008 was published on the Pirate Bay.
End-of-life leaks by developers
Sometimes software developers themselves will leak their source code in an effort to prevent a software product from becoming abandonware after it has reached its end-of-life, allowing the community to continue development and support. Reasons for leaking instead of a proper release to public domain or as open source can include scattered or lost intellectual property rights. An example is the video game Falcon 4.0 which became available in 2000; another one is Dark Reign 2, which was released by an anonymous former Pandemic Studios developer in 2011. Another notable example is an archive of Infocom's video games source code which appeared from an anonymous Infocom source and was archived by the Internet Archive in 2008.
- In late 1998, a number of confidential Microsoft documents later dubbed the Halloween documents were leaked to Eric S. Raymond, an activist in the open-source software movement, who published and commented on them online. The documents revealed that internally Microsoft viewed free and open-source software such as Linux as technologically competitive and a major threat for Microsoft's dominance in the market, and they discussed strategies to combat them. The discovery caused a public controversy. The documents were also used as evidence in several court cases.
- Nintendo's crossover fighting video game series Super Smash Bros. has a history of having unconfirmed content leaked:
- Super Smash Bros. Brawl for the Wii was leaked by a video on the Japanese language wii.com website, revealing unconfirmed playable characters on January 28, 2008 (three days before the game's Japanese release).
- Super Smash Bros. for Nintendo 3DS and Wii U was afflicted in August 2014 by the "ESRB leak", where many screenshots and limited video footage of the 3DS version were leaked by a supposed member of the ESRB. The leak gained traction very quickly due to the screenshots mostly containing elements that the game ratings board would be interested in, such as trophies of suggestively-dressed female characters.
- Recently, several high-profile books have been leaked on the Internet before their official release date, including If I Did It, Harry Potter and the Deathly Hallows, and an early draft of the first twelve chapters of Midnight Sun. The leak of the latter prompted the author Stephenie Meyer to suspend work on the novel.
- On January 31, 2014 the original uncensored version of the South Park episode "201" was leaked, when it was illegally pulled from the South Park Studios servers and was posted online in its entirety without any approval by Comedy Central. The episode was heavily censored by the network when it aired in 2010 against the will of series creators Trey Parker and Matt Stone, and was never formally released uncensored to the public. The episode was the second in a two parter and was censored after the airing of the first part as a result of death threats from Islamic extremists who were angry of the episode's storyline satirizing censorship of depictions of Muhammad.
- In 2015 the unaired Aqua Teen Hunger Force episode "Boston" was leaked online. The episode was set to air during the fifth season, but Adult Swim was forced to pull it to avoid further controversy surrounding the 2007 Boston bomb scare.
- On March 13, 2016, the full list of qualifying teams and first round match-ups for the 2016 NCAA Men's Division I Basketball Tournament leaked on Twitter in the midst of a television special being broadcast by CBS to officially unveil them. The leak exacerbated criticism of a new, two-hour format for the selection broadcast, which was criticized for revealing the full tournament bracket at a slower pace than in previous years.

- The heavenly jukebox on The Atlantic "To show industries how to use the codec, MPEG cobbled together a free sample program that converted music into MP3 files. The demonstration software created poor-quality sound, and Fraunhofer did not intend that it be used. The software's "source code"—its underlying instructions—was stored on an easily accessible computer at the University of Erlangen, from which it was downloaded by one SoloH, a hacker in the Netherlands (and, one assumes, a Star Wars fan). SoloH revamped the source code to produce software that converted compact-disc tracks into music files of acceptable quality." (2000)
