Everything anyone puts on the Internet will sooner or later be vulnerable to hackers

It's sort of like Safe Crackers. There are people who all they do every waking moment is try to break passwords on anything they are interested in worldwide on the Internet. And there are thousands to millions of people like this worldwide.

If there are millions then someone should do the probabilities for literally anything to get hacked worldwide.

Because of this if something isn't vulnerable now it will be in the future. So, because of this literally anything anyone puts on the Internet will be vulnerable.

The main problem of this for me is I would like to know when something is vulnerable. So, people who invent a way to detect when something is made vulnerable by hackers are going to make a real bundle of money both now and into the future.

Knowing that everything eventually will be vulnerable on the Internet worldwide is a given. Knowing when that happens to your stuff could mean life or death to your family. So, this is why detecting when any of your information becomes vulnerable is worth a lot of money including maybe your life and your kids lives now and into the future.

Remember carefully, as of two or more years ago 1 trillion dollars was stolen just from people in the U.S.  per year. (It could therefore be up to 2 trillion or more by now per year).  And this is all done through the Internet.
So, if you wonder why the U.S. or European economy isn't recovering faster this is just one of the many reasons.

Here is the real problem from my point of view: What if a nation like Russia or China gets thousands to millions of their people to crack all the bank internet accounts of private people in say the U.S. or the European Union. And then they just store all these passwords for a year or two. Many people are going to change these passwords and usernames but many will not. So, they just save these usernames and passwords for several years and build up several million or even 50 million of these. Then one day, they strike all at once and drain all these accounts at once. This would be an act of war. But, what if a Country like Russia or China did this to maim our economy in order to attack us monetarily and physically within one month.

This is  my biggest concern the way Putin is acting right now. Even though Putin and China will eventually spar off too in some kind of war, right now he is really pissed at the European Union and the U.S. for ending the Soviet Union. He wants revenge and has gone to a lot of trouble to try to exact this revenge.

This is my biggest concern regarding the Internet right now and for the foreseeable future.

And the problem is they would have all these dollars in their accounts somewhere on earth and could build tanks and missiles with this stolen money. Once bank transfers are completed there isn't much anyone could do especially on such a mass score but to declare war.
