It turned out the most critical trick of Jikto is Google Translate. Using Google Translate for this purpose has already mentioned but this is a good example, definitely. I'm not quite sure about real world impact of this since it should be quite slow because of Google Translate.
There is another gossip and discussion going on about publishing source code of Jikto. It's quite funny. If we really believe a blackhat guy is not able to write such a similar tool after this presentation we should re-consider everything we know about security.
