Time travel and zerodays
Hi, I found something intriguing.
How feasible would it be given a device that could send a short burst of characters with a checksum containing an as-yet-unknown zeroday exploit for a major operating system, for this information to be used?
If an adversary had access to this sort of technology what would be the countermeasure?
Same as sending back fragments of an AES-256 hardware root key or something that.
