When news broke recently that the US Justice Department is preparing criminal charges against WikiLeaks founder Julian Assange, the story reverberated across not only London, where Assange is holed up in the Ecuadorian embassy, but also in Iceland, where a bit player in the WikiLeaks story has been living for five years.

Six years ago, during a military hearing over the actions of Wikileaks source Chelsea Manning, a government witness testified that someone named "Jason Katz" helped WikiLeaks try to crack the password on a particular file. This file contained a video Manning allegedly leaked to the group (she was later acquitted of this charge). Katz has never spoken publicly about the matter and aside from his name and a few details presented in court, the story of his role in the incident has long remained a mystery.
