      NB this is likely caused by some ransomware using a unique .onion domain per user.https://twitter.com/martijn_grooten/status/700606320874020865 …

      @lorenzoFB @martijn_grooten no way to know what the traffic is - that's Tor for you. My conclusions are based on best correlation I can find

      @ProfWoodward @lorenzoFB My source: https://lists.torproject.org/pipermail/tor-talk/2016-February/040318.html … It'd be nice if it were Richochet, but do people really care about audits?

      @martijn_grooten @lorenzoFB looks very plausible as like Ricochet each instance crates an onion service. Whatever it is, it's unprecedented.

      @ProfWoodward @lorenzoFB I remember two previous cases of sharp increase of Tor traffic. First time was botnet, second time measuring bug.

      @martijn_grooten @lorenzoFB very interesting that Locky is obscuring criminals by creating .onion & bitcoin address for each infection.

      @ProfWoodward @lorenzoFB FTR: I have not been able to find confirmation Locky does that.

      @HowellONeill Most likely the recent influx of crypto-ransomware. See also @BleepinComputer's news articles lately.

          @bartblaze @martijn_grooten @ProfWoodward @lorenzoFB plausible given there is a unique .onion for every new infection regardless of payment.

          @bartblaze @martijn_grooten @lorenzoFB key question is has anyone confirmed unique .onion address for each infection?

          @ProfWoodward @bartblaze @lorenzoFB It's suspicious that all stories I find mention the same 6dtxgqam4crv6rr6[.]onion domain name.
