I'm planning a pretty significant demonstration of GSM insecurity at Defcon next week, where I'll intercept and record cellular calls made by my attendees, live on-stage, no user-input required. As you can imagine, intercepting cellphones is a Very Big Deal in the eyes of the law; this blog post is an attempt to reassure everyone that their privacy is being taken seriously despite the nature of the demo. I'm not just making it up either — the EFF have helped significantly with the details.

I'm somewhat of an authority on GSM security, having given presentations on it at Shmoocon and CCC (I'm also scheduled to talk about GSM at this year's Defcon). This is my take on the iPad ICCID disclosure — the short version is that (thanks to a bad decision by the US cell companies, not just AT&T) ICCIDs can be trivially converted to IMSIs, and the disclosure of IMSIs leads to some very severe consequences such as name and phone number disclosure, global tower-level tracking, and making live interception a whole lot easier. My recommendation? AT&T have 114,000 SIM cards to replace and some nasty architectural problems to fix.

After my legal skirmishes with HID a while back, The Register has coverage of my latest RFID work — cloning Passport Cards and Electronic Drivers Licenses from a moving vehicle. Full details will be released at Shmoocon this weekend, but in the meantime there's video of the equipment and articles all over the place. Buy me a beer if you see me at the con! :)
