Black Hat 2009: Breaking SSL with null characters

Update: The video of [Moxie]‘s presentation is now online.

[Moxie Marlinspike] appeared on our radar back in February when he showed sslstrip at Black Hat DC. It was an amazing piece of software that could hijack and rewrite all SSL connections. The differences between a legitimate site and the hijacked ones were very hard to notice. He recently stumbled across something thing that makes the attack even more effective.

1-Wire HVAC monitoring system

1-wire hvac control

The 1-Wire HVAC monitoring system is for residential Geothermal HVAC systems. This project utilizes the so called 1-wire temperature sensor. A single board computer handles the brunt of the work including web accessible trend data. With access to the underling temperatures, the over all system performance may be gauged. Earlier this year we covered a HVAC web enabled monitor that adds an element of control. As the industry adopts modern control architectures, we hope to see more HVAC hacks around.

Music Visualizer (oscilloscope)

The Music visualizer is actually a second build based on an earlier design[Thanks Roger]. The build was influenced by Zyra’s How to make an oscilloscope out of a television. The hack is quite simple, patch the output of an amplifier into the vertical deflection coils of the CRT. This is a good use for that old TV you may have laying around  but don’t want to recycle it just yet. While on the subject we had covered the Mac SE/30 audio visualizer in 2006. For those looking for something a little more hard core, here is a bit about Homemade cathode ray tubes.

Perpetual Ball Roller

This interesting little sculpture caught our eye. Called the Perpetual Ball Roller, it simply rolls a ball on a track. It has both manual and automatic modes with variations in the automatic mode to keep it amusing. This is very elegant, and would be fun to have sitting around to play with. The only problem is the noise. The servo that he is using is quite loud. What could he do to make it function silently?

IntoGrafix: portable TurboGrafix

[Bacteria] tipped us off to his latest portable system mod called IntoGrafix. The TurboGrafix-16 was awesome when it was released. the graphics were, compared to Nintendo, astonishing. Its games were these little cards, like a thick credit card. [Bacteria] wanted to revive his old one in a more portable fashion.  He designed a custom case to fit the whole thing into, which is pretty impressive itself. The screen is the trusty old PSone screen.  The last time we saw a TurboGrafix, it was in a mini Arcade cabinet.
