Just a thought, but can't the OS prevent applications from knowing anything about other applications? Rather than isolating apps by flushing/coloring everything, couldn't the apps not know what else is running? Two apps can't communicate, or one app spy on another, if an app doesn't know what else was/is running.
(Not sure why this is wrong, but confident it must be.)
- psds2 8y agoThese exploits work on a hardware level, and do not require the malicious app to know what else is running. For example, a VM does not know what other VMs are running on the same host in AWS, but Spectre/Meltdown still affected AWS hosts. They are reading data other apps have written to memory.
