Re: [tor-talk] Harvard student used Tor to send bomb threats, gets caught by old-fashioned policework

[tor@xxxxxxxxxxxxx]

This student did some really stupid things and in many ways is a "bad
example" of Tor use, but when Harvard students--even the ones who seem to
have come unhinged and clearly made reprehensible decisions--don't realize
that their university (or other institution's network administration)
probably can and does retain DHCP and/or other information, it's hard not
think that a significant user education and communication opportunity
exists for other Tor users.

I'm not defending this person or what they did in any way, but it does
seem like an example of why offerring more conspicuous, detailed warnings
and feedback to users could help prevent
activists/whistleblowers/journalists/people using Tor to do positive
things from being de-anonymized through similar means. Tor has made huge
strides in this respect (e.g. better update notifications in TBB) over the
past six months, but perhaps there are still some further improvements
that could be made.

In the spirit of Jake's 29c3 talk, I think we can decide as a community
not to brush off high-profile attacks against people using Tor with
arguments like "oh, it was an old Firefox vulnerability and some users
weren't running the latest available code" or "oh, obviously universities,
companies, and maybe ISPs retain enough data to make 'standard police
work' enough to de-anonymize someone using Tor." Instead of these kinds of
"not my department" arguments, we can *instead* conclude that at least in
some cases, making information more visible, accessible, and
understandable to users in more and different ways might still ultimately
be better for Tor users.

A community as innovative as this one can probably figure out ways to
present useful information to users in ways that don't interfere with
their autonomy, too. I realize that media portrayals--especially this past
year--have mischaracterized Tor and its community unfairly, but in
addition to making it clear whether Tor "still works" on technical
grounds, I think we can also choose to be constructive and up our game so
that especially for all the people using Tor who *aren't* jerks, Tor users
will have to be even more thoughtless in order to be de-anonymized through
similar means in the future.
