New Delhi: In view of massive ransomware 'WannaCry' attack, banks in the country did not operate some ATMs running on old software.

The RBI has asked banks to follow the instructions of government organisation CERT-In on ransomware, which has impacted various IT networks in over 150 countries.

Indian Computer Emergency Response Team (CERT-In) has come out with a list of dos and dont's and webcast on how to protect networks from the global ransomware attack.

Most automated teller machines (ATMs) were running fine, there could be some which may not have updated Microsoft's Windows operating system, sources said.

Such ATMs could be prone to attack so as precautionary measure banks running such ATMs refrained from feeding cash, sources added.

However, there was no official information in this regard from the RBI in this connection till late evening.
