Hacking is exploiting a computer system or private network inside a computer. I have come acrossed one case where hackers looted about 94 crores rupees through a malware attack on the server of Pune base Cosmos Bank and cloned about thousands of debit cards over a period of two days. This incident took place on 11th and 13th august 2018.Reports says that the hackers originated from canada. In 2 days hackers managed to withdraw 78 crores from various ATM's in 28 countries including Canada , Hongkong and around 2.5 crores were taken out from India. 14 crores were transferred in a Hong Kong based bank by using fraudulent transactions. The malware attack was operativbe for payment getaways of Visa and Rupay debit cards.

How did the bank came to know about it ? The malware attack was identified only after they observed unusual repeated transactions through visa and rupay cards for nearly 2 hours.
Bank has claimed that all savings , term deposits and recurring accounts of all the customers were fully safe. The bank registered an FIR at Chatushringi police station in the city. The actual loss was identified only after reconciliation with Visa and Rupay.

Was the money recovered by Pune cops as maximum money was withdrawn from various ATM's of different countries?

What measures should be taken by banks to prevent such hacking or cloning of debit cards?

How did the hackers made online transactions when bank had the payment getaway security ?

What are your views and conclusions over this case ? 

My opinion on this case is that maximum amount out of 94 crores has been lost as money was withdrawn through various ATM's of different countries because of which recovering amount would not be possible. Also I feel we should not save online payment or transactions passwords on our devices as it can be easily hacked and transactions are possible resulting into loss of our money.
