BOSTON, Massachusetts, USA -- Friday, August 22, 2014 -- GNU community members and collaborators have discovered threatening details about a five-country government surveillance program codenamed HACIENDA. The program employs a technology known as port-scanning to map every server in twenty-seven countries and detect vulnerabilities to be exploited.

After making key discoveries about the details of HACIENDA, Julian Kirsch, Dr. Christian Grothoff, Jacob Appelbaum, and Dr. Holger Kenn designed the TCP Stealth system to protect unadvertised servers from port scanning.

According to Heise Online, the intelligence agencies of the United States, Canada, United Kingdom, Australia and New Zealand are involved in HACIENDA. The agencies share the data they collect. The HACIENDA system also hijacks civilian computers, allowing it to leach computing resources and cover its tracks.

Some of the creators of TCP Stealth are also prominent contributors to the GNU Project, a major facet of the free software community and a hub for political and technological action against bulk surveillance. Free software is safer because it is very hard to hide malicious code in a program anyone can read. In proprietary software, there is no way to guarantee that programs don't hide backdoors and other vulnerabilities. The team revealed their work on August 15, 2014 at the annual GNU Hackers' Meeting in Germany, and Julian Kirsch published about it in his master's degree thesis.

Maintainers of Parabola, an FSF-endorsed GNU/Linux distribution, have already implemented TCP Stealth, making Parabola users safer from surveillance. The FSF encourages other operating systems to follow Parabola's lead.

The Free Software Foundation supports and sponsors the GNU Project. FSF campaigns manager Zak Rogoff said, "Every time you use a free software program, you benefit from the work of free software developers inspired by the values of transparency and bottom-up collaboration. But on occassions like these, when our civil liberties are threatened with technological tools, the deep importance of these values becomes obvious. The FSF is proud to support the free software community in its contributions to the resistance against bulk surveillance."

The Free Software Foundation works politically for an end to mass surveillance. Simultaneously, the Foundation advocates for individuals of all technical skill levels to take a variety of actions against bulk surveillance.

About Julian Kirsch, Christian Grothoff, Jacob Appelbaum, and Holger Kenn

Julian Kirsch is the author of "Improved Kernel-Based Port-Knocking in Linux", his Master's Thesis in Informatics at Technische Universitat Munchen.

Dr. Christian Grothoff is the Emmy-Noether research group leader in Computer Science at Technische Universitat Munchen.

Jacob Appelbaum is an American independent computer security researcher and hacker. He was employed by the University of Washington, and is a core member of the Tor project, a free software network designed to provide online anonymity.

Dr. Holger Kenn is a computer scientist specializing in wearable computing, especially software architectures, context sensor systems, human machine interfaces, and wearable-mediated human robot cooperation.

About the Free Software Foundation

The Free Software Foundation, founded in 1985, is dedicated to promoting computer users' right to use, study, copy, modify, and redistribute computer programs. The FSF promotes the development and use of free (as in freedom) software -- particularly the GNU operating system and its GNU/Linux variants -- and free documentation for free software. The FSF also helps to spread awareness of the ethical and political issues of freedom in the use of software, and its Web sites, located at fsf.org and gnu.org, are an important source of information about GNU/Linux. Donations to support the FSF's work can be made at

https://donate.fsf.org. Its headquarters are in Boston, MA, USA.

About the GNU Operating System and Linux

Richard Stallman announced in September 1983 the plan to develop a free software Unix-like operating system called GNU. GNU is the only operating system developed specifically for the sake of users' freedom. See https://www.gnu.org/gnu/the-gnu-project.

In 1992, the essential components of GNU were complete, except for one, the kernel. When in 1992 the kernel Linux was re-released under the GNU GPL, making it free software, the combination of GNU and Linux formed a complete free operating system, which made it possible for the first time to run a PC without non-free software. This combination is the GNU/Linux system. For more explanation, see
