SRLabs' works are covered and extended in the new paper by Adrian, a
very good read.

I agree. I was asked to review and test a CryptoPhone (and I still use
it daily). The warnings err on the cautious side of things and single
events only rarely/never mean a real attack. Unless we see more data,
this is completely marketing bullshit.

As someone who tries to move forward an Open Source implementation of
something like their (quite limited) Baseband Monitor (misleadingly
called Baseband Firewall), I am pretty annoyed by their patent:

especially given that Frank Rieger, the owner of the patent, is official
speaker for the CCC and should know better.

bullshit, since they use unmodified Samsung S3 hardware)
