It was inevitable that someone like Russia or China or a private person or organization attack the world's internets at a machine language level

 Any programmer worth his or her salts would realize that something like this was going to happen at some point where the Internet substructure was going to be attacked beneath the level of most operating systems of individual computers or mainframe computers. So, this attack would reach in directly into Servers containing the information of websites around the world at a machine language substructure level. From this substructure level it would reach out and corrupt all servers and computers on earth including banks and governmental computers of all sorts. However, this likely wouldn't trigger virus protections because  the level of the attack would be beneath the level of triggering viral protection software generally speaking simply because it was a machine language attack and not in any specific computer language recognizable to anti-virus protections.

By the way these types of attacks have been going on non-stop at a machine language level by Russia and Putin for almost one year now 24 hours a day. So, it is impossible to know if the damage can even ever be repaired at this point or not without totally redoing the way the world wide internet operates in the first place by either changing all the software and possibly all the hardware too.
