RBI has issued certain instructions on Cyber Security vide circular dated June 02,2016 titled ‘Cyber Security Framework in Banks’, wherein, banks were advised to immediately put in place a cyber-security policy elucidating the strategy containing an appropriate approach to combat cyber threats given the level of complexity of business and acceptable levels of risk.
Banks have advised their respective customers where card details could potentially have been compromised to change the PIN immediately. A few banks have replaced the cards with new ones. In a few cases the change of PIN also was forced by the banks. Thus the impact of the incidence could be controlled.
