There's been a couple of mentions of hiding things on hardware this
week over at twitter and I thought I might post about it here to get a
better understanding of the situation.
"L3 cache can be disabled on Atom CPUs; malware can hide in cache and
not write-back to RAM"
The running discussion this weekend has been with dragosr and ARM SoCs
"ARM processors do have microcode in display system you can use to
hide a backdoor not in memory"

Will Beri save the day? :)
Are we still completely helpless from the software side if the
hardware we're running on is bad?
