Wikileaks now has an online submission system for the first time since 2010. Accessible only as a Tor hidden service, the new page is available at wlupld3ptjvsgwqw.onion. (The Tor Browser can be downloaded here.) Wikileaks' previous system was brought down when a staffer named Daniel Domscheit-Berg split with Wikileaks founder Julian Assange over security issues. Domscheit-Berg held the encryption keys for all the documents received through the system, and ultimately destroyed thousands of submissions rather than let them be published in a way that might endanger the sources.

The new submission page has a number of fields where visitors can describe the nature of the leaked material, which groups had access to it, and whether the sources are under any threat from the publication. It also gives leakers a chance to control when the material is leaked, either requesting an immediate publication or mark materials as only to be published after a certain date or a certain event has occurred. "If you have any issues talk to WikiLeaks," the organization's Tips for Sources page advises. "We are the global experts in source protection."
