The only means I could ever see being possible for OS protection against ransomware would be to restrict file system access only to code-signed executables.

It won't work. If all executables (really executables and libraries) are signed, then vulnerable executables that are present on the system must be signed, too. So whenever any vulnerability is exploited, file access is open.

Ah, but now you know exactly where that executable came from and whether or not to trust it.

Once the data is written, you have no idea how exactly it happened.

In an world of online forums, it wouldn't take all that long for the community to find the correlation between what signed program was installed across systems that corresponded to incidents.

That would require a very large number of people with and also very large number of people without a given program reliably determining success of a particular exploit. It does not work.

You already see that with unsigned software.

At best, it could find blatant and obvious trojan horse programs. Could because it worked when it was unheard of for legitimate software to perform anything invasive or communicate with the vendor, so trojans stood out like sore thumbs.

For vulnerabilities it never worked. They are all either published by their authors or found by proactive testing, or by observation of exploits in the wild.
