Ashley Madison : The Danger of The Last 4 Numbers
I am sure that everyone has heard that the popular dating website that specialized in marriage infidelity was hacked a few weeks ago. The brazen hackers have essentially open-sourced the entire AshleyMadison.com website and released several massive database dumps containing customer profiles, customer details (name, address, email address, phone number) and a limited amount of payment information including the last 4 digits of the credit card number. Several people I have spoken to in person do not see this as a threat as you would need the entire card number (and CVV2) before you can use the card for fraud. I have to disagree as it is fairly trivial to turn the last 4 digits of the credit card number into the entire credit card number using nothing more then a phone and a bit of charisma.
