[tor-talk] Cancelled black hat talk

[Roger Dingledine]

Hi folks,

Journalists are asking us about the Black Hat talk on attacking Tor
that got cancelled. We're still working with CERT to do a coordinated
disclosure of the details (hopefully this week), but I figured I should
share a few details with you earlier than that.

1) We did not ask Black Hat or CERT to cancel the talk. We did (and still
do) have questions for the presenter and for CERT about some aspects
of the research, but we had no idea the talk would be pulled before the
announcement was made.

2) In response to our questions, we were informally shown some
materials. We never received slides or any description of what would
be presented in the talk itself beyond what was available on the Black
Hat Webpage.

3) We encourage research on the Tor network along with responsible
disclosure of all new and interesting attacks. Researchers who have told
us about bugs in the past have found us pretty helpful in fixing issues,
and generally positive to work with.
