colinneagle writes "If you use the Z-Wave wireless protocol for home automation then you might prepare to have your warm, fuzzy, happiness bubble burst; there will be several presentations about attacking the automated house at the upcoming Las Vegas hackers' conferences Black Hat USA 2013 and Def Con 21. For example, CEDIA IT Task force member Bjorn Jensen said, 'Today, I could scan for open ports on the Web used by a known control system, find them, get in and wreak havoc on somebody's home. I could turn off lights, mess with HVAC systems, blow speakers, unlock doors, disarm alarm systems and worse.' Among other things, the hacking Z-Wave synopsis adds, 'Zigbee and Z-wave wireless communication protocols are the most common used RF technology in home automation systems...An open source implementation of the Z-wave protocol stack, openzwave, is available but it does not support the encryption part as of yet. Our talk will show how the Z-Wave protocol can be subjected to attacks.'"
