Bloomberg is reporting that WikiLeaks may have used music- and photo-sharing networks to obtain and publish classified documents. “WikiLeaks, which has said it doesn’t know who provides it with information, may seek out secret data itself, using so-called “peer-to-peer” networks” according to Tiversa Inc. Tiversa estimates that as much as half of the postings by WikiLeaks could originate from information siphoned from peer-to-peer users.

Bloomberg and Reuters both report that Rudolph Elmer, the banker who gave data to WikiLeaks, was arrested late Wednesday for possible violations of Swiss bank law.
