I still don't fully understand — if a low-bit privkey public key is exposed, how could someone potentially derive the private key from it? Could someone please explain how that's possible?
Brute-forcing using the public key is much cheaper than brute-forcing using an address only.

if he didn't use it, he could go back and compile an .exe with o.random. Smiley
This is not how development works. You can't just "compile a binary" after sticking "o.random" somewhere and expecting it to work.
My friend, I didn't mention any binary. I said that he didn't provide the source code and therefore I don't know what he used to compile VBCr.exe in the end. Since I don't want to get his source code at all, I asked if he could recompile the code he has using o.random if that's not the type of random that the executable uses Smiley Simple, friend
