Decap of a Cell Phone SIM card [video]

If you want to understand more about what the glitching protection is about Scanlime recently made a very good video where she grabs firmware from a drawing tablet using such an attack.<p><a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=TeCQatNcF20" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=TeCQatNcF20</a>

sim cards are as capable as 80s computers and run the JVM.<p><a href="http:&#x2F;&#x2F;www.extremetech.com&#x2F;computing&#x2F;161870-the-humble-sim-card-has-finally-been-hacked-billions-of-phones-at-risk-of-data-theft-premium-rate-scams" rel="nofollow">http:&#x2F;&#x2F;www.extremetech.com&#x2F;computing&#x2F;161870-the-humble-sim-c...</a>

Hmm so even if you can ever buy a secure phone you trust, you need to put another, completely opaque, computer into it to make it function (on cell networks anyway.)

There was a talk on blackhat or defcon about the abilities of these controllers, running mini java applications and other cool things. I remember it being said finding necessary SDK&#x27;s were very difficult and sometimes secretive. Makes me wonder.

That is a very well-made video.<p>Like the video creator, I&#x27;m very surprised the humble SIM card has been made so capable!

Honest question, why there is a need for a ARM based processor on that SIM card? AFAIK, the role of the SIM is to securely store all kind of IDs and PINs and contacts.<p>I am quite sure that my first SIM card, 20 years ago, didn&#x27;t have such setup and worked, quite the same.
