Submission + - Cellphone interception at Defcon (tombom.co.uk)

Submitted by ChrisPaget on Sunday July 25, 2010 @09:08PM

ChrisPaget writes: 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.

Submission + - AT&T breach worse than initially thought? (tombom.co.uk)

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 buying an almost-new Alienware laptop on eBay, I've spent the last week trying to get hold of a Smart Bay caddy to connect a second hard drive (about $150 for $5 of bent metal). 4 different Alienware teams have refused to even give me a price on this accessory, instead accusing me of stealing the machine since I didn't buy it directly from them. Details here. All I have to do is persuade the seller to add me as an authorized user of *his* Alienware account — they have no concept of "ownership transfer" and instead assume that if you're not in their system, you must be a thief."

The shield that comes with the passport card is effective, at least as far as my research so far has suggested. It's worth mentioning though that according UW / RSA, the shields supplied with the electronic drivers license in Washington are ineffective at preventing reads (although they do reduce range somewhat) - http://www.rsa.com/rsalabs/node.asp?id=3557

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! :)
