Is there any relation between specific hardware (like specific kind of CPU etc) or laptop manufacturing brands and the hacked environments run on? Can this be measured in any way like stolen data or get owned by sending any exploit to an owner of such a hardware?
My first thought - should be not since the OS system is the hub for exploits etc. I guess there is no way to run BIOS execution code from the layer of Windows OS or OS X, neither Linux (supposing exploit took control over our system)?
But what about hidden exploits built in by manufacturers? Has anyone in this field been caught red-handed? Should I avoid any particular manufacturer if privacy and security is my priority?
