Defcon 19: Vulnerabilities of Wireless Water Meter Networks

Security researcher John McNabb presented this talk at the Defcon 19 (2011) conference highlighting vulnerabilities of wireless water meter systems. John managed a small water system for 13 years and draws on his experiences in this presentation covering water security systems and more importantly the hardware, software, topology, and vulnerabilities of wireless water meter networks […]

Defcon 19: Network Monitoring with Arduino

Steve Ocepek, Director of Security Research, Trustwave SpiderLabs presented this talk at Defcon 19 (2011). He harkens back to the days of blinking modem lights, and demonstrates how to create a modern day “blinking light” network monitoring device using the Arduino Uno along with itead Studio’s Color Shield. Dubbed the cerealbox, this design interfaces with […]

Defcon 19: build your own radar system

At the Defcon 19 (2011) conference Michael Scarito demonstrated how to construct your own radar system. The project is based on a design by Dr. Greg Charvat from MIT and uses synthetic aperture techniques to generate a two- or three-dimensional image. (You can read Dr. Charvat’s research paper here.) The hardware operates in the 2.4 […]

Defcon 19: Hacking over power lines

Dave Kennedy (ReL1K) presented this talk at last summer’s Defcon 19 conference demonstrating the relative insecurity of home automation devices, such as X10, HomePlug and ZWave modules, which communicate either locally over power lines or via RF in the ISM bands. The presentation covers usage of the Teensy Arduino-based device to emulate a keyboard when […]

Derbycon/Defcon: battery firmware hacking

We use laptops everyday and as long as the battery isn’t dead we probably don’t give it much thought. It turns out that most laptop batteries contain a smart chip which controls battery charge rate and ensures safety parameters are observed among other purposes. In this video from the recently concluded Derbycon conference in Louisville, […]
