Julian Assange is the founder of WikiLeaks.org, a Web site that "collect[s] documents and imagery that governments and other institutions regard as confidential and publish[es] them." He is profiled by Raffi Khatchadourian in the June 7, 2010 issue of The New Yorker.

Assange is an international trafficker, of sorts. He and his colleagues collect documents and imagery that governments and other institutions regard as confidential and publish them on a Web site called WikiLeaks.org. Since it went online, three and a half years ago, the site has published an extensive catalogue of secret material, ranging from the Standard Operating Procedures at Camp Delta, in Guantánamo Bay, and the "Climategate" e-mails from the University of East Anglia, in England, to the contents of Sarah Palin's private Yahoo account. The catalogue is especially remarkable because WikiLeaks is not quite an organization; it is better described as a media insurgency. It has no paid staff, no copiers, no desks, no office. Assange does not even have a home. He travels from country to country, staying with supporters, or friends of friends–as he once put it to me, "I'm living in airports these days." He is the operation's prime mover, and it is fair to say that WikiLeaks exists wherever he does. At the same time, hundreds of volunteers from around the world help maintain the Web site's complicated infrastructure; many participate in small ways, and between three and five people dedicate themselves to it full time. Key members are known only by initials–M, for instance–even deep within WikiLeaks, where communications are conducted by encrypted online chat services. The secretiveness stems from the belief that a populist intelligence operation with virtually no resources, designed to publicize information that powerful institutions do not want public, will have serious adversaries.
