    Smartphones are susceptible to malware and carriers have enabled NSA snooping, but the prevailing wisdom has it there’s still one part of your mobile phone that remains safe and un-hackable: your SIM card.

    Yet after three years of research, German cryptographer Karsten Nohl claims to have finally found encryption and software flaws that could affect millions of SIM cards, and open up another route on mobile phones for surveillance and fraud.

    Wonder if sim cards use similar encryption to the "chip" cards in Europe...

    Consumers using SIM cards more than three years old should request new cards from their carriers.

    Yeah "our" unique problem is the SIM cards that you purchase overseas when traveling, or the ones from carriers that are not really good at using newer technology.

    The option to use AES or even the older triple DES for encryption, a lot of the SIM cards still use DES, which is crackable in days using FPGA clusters and minutes using rainbow tables (a similar exploit was used to break the GSM A5/1 cipher a while back)

    Its not that odd to have a sim from 3 years ago. Mine is .. 7 years old I think? been through a lot of phone in those 7 years, and even cut the chip to mini, but its still 'working'

    might finally get retired now.

    my two main cards would be that old, but I was able to replace both when I went to mini.
