The last settlement related to the data breach has been achieved by Heartland Payment Systems. The payment processor has agreed to pay up to $5 million to Discover Financial Services in relation to a massive data compromise that hit the company in 2008.

Last January the payment processing firm revealed that malicious software in its processing system had been found, potentially compromising the card data of millions of people.

The $5 million settlement with Discover follows a $41.4 million pay-out to MasterCard, a $60 million bill from Visa and a $3.6 million deal with American Express. In December last year the embattled processor also agreed to pay up to $2.4 million to settle a consumer cardholder class action suit

Announcing the latest agreement, Bob Carr, Heartland's chairman and chief executive officer, says: "This settlement marks our final agreement with a card brand related to the intrusion."
