writes A presentation on a low-budget method to unmask users of a popular online privacy tool Tor will no longer go ahead at the Black Hat security conference early next month. The talk was nixed by the legal counsel with Carnegie Mellon's Software Engineering Institute after a finding that materials from researcher Alexander Volynkin were not approved for public release, according to a notice on the conference's website.
Tor project leader Roger Dingledine said, "I think I have a handle on what they did, and how to fix it. ... Based on our current plans, we'll be putting out a fix that relays can apply
that should close the particular bug they found. The bug is a nice bug, but it isn't the end of the world." Tor's developers were "informally" shown materials about the bug
, but never saw any details about what would be presented in the talk.
