An Iranian hacker leaked the information of the 3 million credit cards in order to highlight security vulnerabilities in the banking system.
The hacker was identified as 'Khosrow Zare Farid', who was the manager of the Eniak company.
According to Kabirnews report, one year ago itself, he reported about the vulnerability to all the CEO of banks in Iran. The source says none of them replied to him. So he decided to publish the information.
As the result of the security breach, 3 of Iranian banks including Saderat, Eghtesad Novin and Saman sent SMS for their clients to update the password of their debit cards. Also the Central Bank of Iran urged customers to change their password for the credit cards.
