I Don't Understand
...why ransomware attacks like WannaCry are so hard to trace. They are asking for money, so the money should be traceable, at least by the banks carrying out the transfers. Of course some banks may have an interest in facilitating this kind of crime. How about just nuking them, virtually or actually? The virtual nuke would be just freezing them out of the international banking system and seizing any external assets of the banks and their principals.
I get it that a lot of tax evaders, drug dealers, corrupt officials and the banks that serve them would wanna cry, but is there any actual reason this would be a bad idea?
