On the last day, I started off by listening to some of the lightning talks, and then:
- Christian Louis -Sicherheit bei VoIP-Systemen, eine Einführung (cache): as the title suggests, a quite high-level overview on security protocols in common VoIP implementations. Mildly interesting.
- Emmanuel Goldstein - Protesting in the new Millenium (cache): uhm, don't remember much of this talk, although I was in the room all the time.
- Dan Kaminsky - MD5 To Be Considered Harmful Someday (cache): another Dan-Kaminsky-the-rockstar - show, with a few novel ideas on how to make use of MD5 collisions. Went out early, because (again) I couldn't stand his presentation style, which makes every normal sentence sound as if something important was just said.
- phar - Secure Instant Messaging (cache): some infos on IM security (and attacks on AIM), and thoughts on how to improve instand messaging security for business applications
- Fravia - How to find *anything* on the Web (cache): This was more or less the same talk as he held on 19C3, with some additional information. Unfortunately, the presentation style was very unorganized - and at the same time, he would have enough material for a half-day session. Fortunately, there's all the info on his searchlores.org website (cache), with the 21C3 workshop data here (cache).
- Major Malfunction - Old Skewl Hacking: Infra Red (cache): some funny stuff on infra red devices like garage door openers, and on how to hack hotel room TV appliances through additional IR signals not present on the standard remote.
- Frank Rieger, Ron - Security Nightmares 2005 (cache): The traditional session with remarks on last year's predections and new stuff from the patented security nightmare crystal globe. Quite funny and entertaining, as always, but a bit light on content.
- Tim Pritlove - Closing Event (cache): yes. we've all been there, see you next year.
