Thanks for sharing the link Bjørn!
This is concerning me :
https://media.defcon.org/DEF%20CON%2023/DEF%20CON%2023%20presentations/DEFCON-23-Mickey-Shkatov-Jesse-Michael-Scared-poopless-LTE-and-your-laptop-UPDATED.pdf
So does that mean that there is nothing to do from the host perspective
to "secure" the system?
If an internal Linux is run inside the chip and that this Linux can be
rooted or externally executed some commands...
Does that mean that if the chip/baseband is compromised then the whole
host system is as well? No way to protect the host against this?
I am very interested to heard about any info as now I am in doubt to buy
a laptop with a chip like this included...(if I spend time to enforce my
system and one little piece destroy all the rest :-(
many thanks
