Internet leak

Last updated

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.

Confidentiality involves a set of rules or a promise usually executed through confidentiality agreements that limits access or places restrictions on certain types of information.

Internet Global system of connected computer networks

The Internet is the global system of interconnected computer networks that use the Internet protocol suite (TCP/IP) to link devices worldwide. It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing. Some publications no longer capitalize "internet".

Software non-tangible executable component of a computer

Computer software, or simply software, is a collection of data or computer instructions that tell the computer how to work. This is in contrast to physical hardware, from which the system is built and actually performs the work. In computer science and software engineering, computer software is all information processed by computer systems, programs and data. Computer software includes computer programs, libraries and related non-executable data, such as online documentation or digital media. Computer hardware and software require each other and neither can be realistically used on its own.


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.

In computing, source code is any collection of code, possibly with comments, written using a human-readable programming language, usually as plain text. The source code of a program is specially designed to facilitate the work of computer programmers, who specify the actions to be performed by a computer mostly by writing source code. The source code is often transformed by an assembler or compiler into binary machine code understood by the computer. The machine code might then be stored for execution at a later time. Alternatively, source code may be interpreted and thus immediately executed.

The Concurrent Versions System (CVS), also known as the Concurrent Versioning System, is a free client-server revision control system in the field of software development. A version control system keeps track of all work and all changes in a set of files, and allows several developers to collaborate. Dick Grune developed CVS as a series of shell scripts in July 1986.

The File Transfer Protocol (FTP) is a standard network protocol used for the transfer of computer files between a client and server on a computer network.

There were many cases of source code leaks in the history of software development.

MP3 is a coding format for digital audio. Originally defined as the third audio format of the MPEG-1 standard, it was retained and further extended—defining additional bit-rates and support for more audio channels—as the third audio format of the subsequent MPEG-2 standard. A third version, known as MPEG 2.5—extended to better support lower bit rates—is commonly implemented, but is not a recognized standard.

Fraunhofer l3enc was the first public software able to encode PCM (.wav) files to the MP3 format. The first public version was released on July 13, 1994. This commandline tool was shareware and limited to 112 kbit/s. It was available for MS-DOS, Linux, Solaris, SunOS, NeXTstep and IRIX. A licence that allowed full use cost 350 Deutsche Mark, or about 250 US$.

Electronic Arts American interactive entertainment company

Electronic Arts Inc. (EA) is an American video game company headquartered in Redwood City, California. It is the second-largest gaming company in the Americas and Europe by revenue and market capitalization after Activision Blizzard and ahead of Take-Two Interactive and Ubisoft as of March 2018.

End-of-life leaks by developers

Sometimes software developers themselves will intentionally 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 [31] [32] which became available in 2000; another one is Dark Reign 2 , [33] [34] 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. [35]

Abandonware is a product, typically software, ignored by its owner and manufacturer, and for which no support is available. Although such software is usually still under copyright, the owner may not be tracking copyright violations.

"End-of-life" (EOL) is a term used with respect to a product supplied to customers, indicating that the product is in the end of its useful life, and a vendor stops marketing, selling, or rework sustaining it. In the specific case of product sales, a vendor may employ the more specific term "end-of-sale" (EOS). The time-frame after the last production date depends on the product and relates to the expected product lifetime from a customer's point of view. Different lifetime examples include toys from fast food chains, mobile phones and cars.

The public domain consists of all the creative works to which no exclusive intellectual property rights apply. Those rights may have expired, been forfeited, expressly waived, or may be inapplicable.

The Halloween documents comprise a series of confidential Microsoft memoranda on potential strategies relating to free software, open-source software, and to Linux in particular, and a series of media responses to these memoranda. Both the leaked documents and the responses were published by Eric S. Raymond in 1998.

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)
