Cult of the Dead Cow
spokesperson and developer for The Tor Project
Jacob Appelbaum is an independent computer security researcher and hacker. He was employed by the University of Washington, and is a core member of the Tor project. Appelbaum is known for representing Wikileaks at the 2010 HOPE conference. He has subsequently been repeatedly targeted by US law enforcement agencies, who obtained a court order for his Twitter account data, detained him 12 times at the US border after trips abroad, and seized a laptop and several mobile phones.
Appelbaum, under the handle "ioerror", has been an active member of the Cult of the Dead Cow hacker collective since 2008, and is the co-founder of the San Francisco hackerspace Noisebridge with Mitch Altman. He has worked for Kink.com, Greenpeace and has volunteered for the Ruckus Society and the Rainforest Action Network. He is also an ambassador for the art group monochrom.
Research and activism
In 2005, Appelbaum gave two talks at the 22nd Chaos Communication Congress, Personal Experiences: Bringing Technology and New Media to Disaster Areas, and A Discussion About Modern Disk Encryption Systems. The former covered his travels to Iraq - crossing the border by foot, the installing of Internet satellites in Kurdistan, and his visit of New Orleans post-Hurricane Katrina. The latter talk discussed the legal and technical aspects of full disk encryption. At the 2006 23rd Chaos Communication Congress, he gave a talk with Ralf-Philipp Weinmann titled Unlocking FileVault: An Analysis of Apple's Encrypted Disk Storage System. The duo subsequently released the VileFault free software program which broke Apple's FileVault security.
He is a contributor to Julian Assange's 2012 book Cypherpunks: Freedom and the Future of the Internet along with Andy Müller-Maguhn and Jérémie Zimmermann.
He regards Tor as a "part of an ecosystem of software that helps people regain and reclaim their autonomy. It helps to enable people to have agency of all kinds; it helps others to help each other and it helps you to help yourself. It runs, it is open and it is supported by a large community spread across all walks of life." 
Detention and investigation
Appelbaum has been detained at airports and had his electronic equipment seized several times. In 2010, the US Department of Justice obtained a court order compelling Twitter to provide data associated with the user accounts of Appelbaum, as well as several other individuals associated with Wikileaks. While the order was originally sealed, Twitter successfully petitioned the court to unseal it, permitting the company to inform its users that their account information had been requested.
Appelbaum is an atheist of Jewish background and identifies himself as bisexual. He also is an anarchist and enjoys photography. He has moved to Berlin, where he has applied for residence authorization, his stated reasons include that he doesn't want to go back to the USA because he doesn't feel safe  and that privacy protections are better in Germany than in the US. In September 2013, he testified before the European Parliament, mentioning that his partner had been spied on by men in night-vision goggles as she slept.
