WATERVILLE, Maine (2/16/09)--Losses due to the Heartland Payments Systems data breach have tripled for one Waterville, Maine-area credit union. Healthfirst CU was first notified Jan. 12 that 261 of its members’ cards were compromised. Now, the credit union has learned that 550 more cards were affected--putting the total at more than 800, Lynda Quirion of Healthfirst CU, told BankInfoSecurity.com (Feb. 12). The total amount taken from member’s cards is between $60,000 to $70,000. Replacing the cards will cost the credit union $2,500, Quirion said. Healthfirst’s staff also is feeling strained by the breach. The credit union already has spent 300 hours contacting members and re-issuing cards, Quirion told the news outlet. Many of the fraudulent purchases were made at convenience stores, gas stations, and fast food restaurants, the credit union said. Healthfirst has $13 million in assets.
