According to Heise online, the intelligence agencies of the United States, Canada, United Kingdom, Australia, and New Zealand, have used HACIENDA to map every server in twenty-seven countries, employing a technique known as port scanning. The agencies have shared this map and use it to plan intrusions into the servers. Disturbingly, the HACIENDA system actually hijacks civilian computers to do some of its dirty work, allowing it to leach computing resources and cover its tracks.

But this was not enough to stop the team of GNU hackers and their collaborators. After making key discoveries about the details of HACIENDA, Julian Kirsch, Christian Grothoff, Jacob Appelbaum, and Holger Kenn designed the TCP Stealth system to protect unadvertised servers from port scanning. They revealed their work at the recent annual GNU Hackers' Meeting in Germany.

Please be sure to share this with everyone you know who cares about bulk surveillance.

We must fight the political battle for an end to mass surveillance and reduce the amount of data collected about people in the first place. On an individual level we have to do everything we can to thwart the surveillance programs that are already in place.

No matter your skill level, you can get involved at the FSF's surveillance page.

Ethical developers inside and outside GNU have been working for years on free software that does not keep secrets from users, and programs that anyone can review to remove potential vulnerabilities. These capabilities give free software users a fighting chance against surveillance. Now, our community is turning its attention to uncovering and undermining insidious programs like HACIENDA. Free software and its ideals are crucial to putting an end to government bulk surveillance.

Share this news with your friends, to help make people aware of the importance of free software in fighting bulk surveillance.

Jacob Appelbaum of the TCP Stealth team gave a remote keynote address at the FSF's LibrePlanet conference this year. Watch the recording of "Free Software for freedom: Surveillance and you."
