UTI Being hacked is Digital Armaggedon - that is unfixable. UTI comes before anything else in the Boot process, so if you own that, you can report back to who ever is trying to fix the system that nothing is there.

SHA verified Boot CD's, hardware wallets - nothing is secure!
If I was a Individual hacker - I would wait for years until the day the bug is fixed in hardware - likely 2 - 3 years from now, and on the day the before the first safe system is released, I would clean out every BTC wallet whose encryption key I had obtained.

If I was a state actor - you could wipe every infected control system in the World - if there is even one infected system on the network they are all infected, and no government can shutdown, say, every computer in a nuclear plant, replace them all, and never put any of them on the Internet again.

These idiots at the CIA have paid a bunch of Genius hackers to develop them a tool that makes no network safe. You could shut down damns, nuclear plants, wipe entire data centers, send us back to the stone age - or at least the 1970's
