This attack will remain in history due to the number of customers affected and the emergency measure adopted by the financial institution.

Tesco has downplayed the amount of money that was stolen from the customers’ accounts, anyway the bank will refund all losses and has apologized for poor customer service that supported the users that tried to receive information by calling the bank over the weekend.

According to the Telegraph, one man tweeted his available balance had dropped by £700 without and he never made a transaction.

“We have been hacked, all money gone, no email or text! Appalling response from Tesco so far nobody answering,” one tweeted.

While security experts are trying to identify the threat actor behind the attack, Mr Higgins refused to speculate on the possible culprit.

“In the modern world it is impossible to be totally impregnable. We are in dialogue with the national crime agencies and with the financial conduct authority.” he said.
