I think they really missed an opportunity to call their network "SimShady".
-
one of these defcon talks popped up in my suggested videos, hours later I'm deep down the YouTube rabbit hole.

Gotta respect speaker 2. He was clearly uncomfortable with public speaking, but he dropped a huge load of interesting information.
-
Very complicated but interesting to watch. I never realised that the SIM card was a smart CPU based card. I thought it was just a EEPROM.
-
This put me on the road to becoming one of the few open-source JavaCard developers. What a talk. They reside in smartcards now, including implants, which I help build.
-
I would love to see a talk about actually running the GSM network. That would be interesting.
-
I was thinking this talk was out of date, then I saw it was from three years ago and realised these guys were the ones who pioneered sim apt
-
I used to work at a mobile service provider, where we had these little card reader/writers with which you could program these. From what I remember, we wrote our own little apps.

TIL that SIM cards have much more computational power than the Apollo 11 computer. Most people know that the Apollo 11 computer was primitive in contrast to today's technology, that even a £1 calculator has more power than it did, but it's amazing that SIM cards have up to 250kb of storage, 64kb ram and run at 30mhz while the Apollo 11 computer ran at 0.043mhz and had 4kb ram and a 32kb hard disk.

the shot gave big man confidence

Absolutely fantastic work guys. You're an inspiration to us all.
-
And here am I, 6 years later with my dual SIM phone...

"This is used by the ISIS competitor, Google Wallet" LOL

In the 2000s in Australia Vodafone sim cards could be used for gprs data (dial up speed pre 3g) without any activation of the card just chuck it in and set the connection to Vodafone and off you go. just used to get $2 sims from the piles in shops. You would get about a week to 2 weeks before the card stopped working then you would use another $2 card. you always got your free calls from a payphone and a straw. useless info now :(

How quickly my inner nerd has come out after finding defcon!
-
I'm so glad to see this talk back. Ugh censorship.
-
Memories...I used to do this back in the early 2000...I still have java cards and the card readers laying around.
-
Big dude with the glasses might seem soft spoken but he's a technological beast
-
I want to know more about how they set up their own mobile network out in the middle of nowhere!
-
Fug guys that's a lot of work and we'll prepped
