TBH I'm having trouble reconciling that post. If they caught it early there shouldn't be much "verification" needed. Worst case, restore last known good backup and replay known good transactions. Either they don't have a clue when and how the attack started or the whole thing is made up. To shut it down for a week is a truly confidence-inspiring act by a wannabe financial institution boasting to change the "industry".
