Amazonian here. My views are my own; I do not represent my company/corporate.

We do our very best. But I don't know anyone here who would say "it can never happen". Security is never an absolute. The best processes and technology will lower the likelihood and impact towards 0, but never to 0. Viewed from that angle, it's not if Amazon will be hacked, it's when and to what extent. It is my sincere hope that if we have an incident, we rise up to the moment with transparency and humility. I believe that's what most of us are looking for during and after an incident has occurred.

To our customers: Do your best, but have a plan for what you're going to do when it happens. Incidents like this one here from checkout.com can show examples of some positive actions that can be taken.
