@delroth_ You can MITM your SIM + pressure provider to fix your card. You can test if the cracker I wrote can break it at #OHM @Linuzifer
So, any counter-measures to avoid people sending crafted OTA to my SIM card? Karsten's talk at #OHM2013 made me really worried.

@delroth_ change your SIM card for USIM. -
@FlUxIuS are USIM not broken by this attack? I think they can still be OTA reprogrammed via SMS. - 1 more reply
