ECDSA smartphone key extraction using $2 magnetic probe

Previous exciting works by the same research group (already discussed on HN):

- Acoustic cryptanalysis : https://www.cs.tau.ac.il/~tromer/acoustic/

- Get Your Hand Off My Laptop : http://www.tau.ac.il/~tromer/handsoff/

I saw a live demo of the latter at the CHES 2014 conference in Busan, it was really impressive.

Now to be honest, I'm less impressed by this new one because I already saw a very similar attack on a smartphone using an EM probe (except maybe it was on the RSA cryptosystem). I'm not entirely sure but it may have been at the CRI demo stand at the CARTES convention in Paris in either 2012 or 2013.

CRI had a demo like that at RSA (the conference) around that time, so I think your recollection is right.
