America’s Thrift Stores, a donations-based thrift store chain that supports Christian ministries, announced this week that it lost customers’ credit card information after it was breached by hackers based in Eastern Europe.

“This breach allowed criminals from Eastern Europe unauthorized access to some payment card numbers,” company CEO Ken Sobaski said in a statement. “We urge all shoppers — whether at our stores or others — to check their credit and debit card statements every month for any fraudulent charges.”
