One other point not mentioned, is copying 4GiB of data across a network does take a bit of time, over the internet even longer. This link link is to a 2.9GB file so you can see how long it will take to download 4GiB over your internet connection. There is also the point on ASLR making life difficult, well if ASLR is switched on, there are a number of other options which may be also switched on in that part of the system, eg Control Flow Guard, DEP (been around for a couple of decades now), forced ASLR, bottoms up ASLR, High Entropy (more useful if you have shed loads of ram installed than minimum amounts), SEHOP ( link ) and Validate Heap integrity which are all on by default now a days in the systems I have seen. Then there is group policy where in Pro or above, you can control what programs run, in home you can add some of the group policy reg keys and get the same functionality when the functionality exists in the dll's. It reminds me of the bug where you could use notepad to pop a shell, but I'd be interested to see if this would still work with core isolation switched on, Defender Application Guard switched on to sandbox different apps, not just Edge. The number of installers for various apps which dont handle Ransomware Protection aka Controlled Folder Access being switched on, even some big names like Dell's Data Vault havent got that sorted yet, but I still think the best way to hack a system is the old way and get them to download and install an app which can run
