It's consequences are now being felt. Though not much is known about malware and which bank's ATM have been infected, it is clear that this breach would have affected other banks too. Hardship faced by people whose debit cards were blocked and not being able to withdraw cash from ATM's could further alleviate common man from using technology and question security of all initiative taken to move towards a cashless society.
It is time that organisations conduct their due diligence when they inter-connect with other company networks and also ensure that their customers are well protected. Banking industry has to move fast to protect against such malware as we will see more such attacks in future.
