The word on why we got treated to a false alarm about missiles heading for Hawaii is this: (over-simplification alert!)
- What was supposed to be an internal-only test message got misdirected to the live alert system
- When presented with the much-maligned, "Are you sure?" prompt, the operator did what we all do reflexively.
They clicked Yes.
There's a security lesson here. Stop and take a breath and read all these prompts. Clicking OK automatically is the road to ruin. So many security-sensitive things are prompted like this. You get this one chance to stay safe. Take it.
