Yeah, all this chatter about technologies and processes that could have saved this: you don't think someone in all of Korean government knew about that?

The problem is more likely culture, hierarchy or corruption. Guaranteed several principal security architects have been raising the alarm on this internally along with much safer, redundant, secure alternatives that came with an increased cost. And decision makers who had a higher rank/social/networking advantage shot it down. Maybe the original storage designer was still entrenched there and sabotaging all other proposals out of pride. Or there's an unspoken business relationship with the another department providing resources for that data center that generates kickbacks.

Assuming nobody knows how to do an offsite backup or is plain ignorant of risk over there is arrogant.
