Who we are and what we do
We are a group of international hackers.
We do IT security work. We are not for hire. All of our work is for the public.
We research and publish tools and academic papers to expose fishy IT security that just isn’t secure. We also develop and publish tools to help the IT Security movement.

Beside our public work we engage with some leading IT Security companies to push security into the right and meaningful direction. We have been editor in chief of the Phrack Magazine and occasionally we speak at conferences. We have contributed to various Internet Standards through our engagement with the Internet Engineering Task Force and other organizations. We are a major donor to the EFF.
The best way to meet us is at one of the IETF meetings or a hacker convention such as HITB or the CCC Congress.
Since 1995, three of our members got arrested (0 convicted), one got raided, two received visits by the BKA (Germany’s FBI) and BND (Germany’s NSA) and one got blackmailed by the British GCHQ. Yet the very same organizations listen when we speak at conferences. And use our tools. We see ourselves as artists. We believe in Freedom, Diversity, Privacy, Security and rights for the citizens.
(We are not anti-government. We are anti-stupidity. Unfortunately there seems to be considerable overlap.)
Only once did we allow an interview of two of our members: 30 years of hacking for fun and no profit
