Tech Updates

For the last two years Chapter 18, Smith et al have been studying AKA (authentication and key agreement). One candidate for AKA is MILENAGE which, in 2014 & published 2015, was hacked using DPA (a side channel attack). Having spent 2016 researching through a huge range of document, presentation, test data and scripts etc., it was noted there had been nothing written as to what to look for and

A regular question that arises, "is it possible to bypass a PIN blocked SIM card?"For a quick solution it is best to go to the operator to obtain a PUK code where there has been 3 CHV1 attempts and access is now blocked.If it is 10 CHV1 attempts and blocked ([unless you know and have the test tools to e.g. slow the card]) then the operator may request that you send it to them and they in turn (
