The Quincy Credit Union (QCU) may have had up to 700 customers victimized by an ATM skimming scam that took place earlier this month.
Stewart Steele, CEO of the Qunicy, Mass. credit union, estimates that 670 accounts were compromised when someone attached a skimming device to one of the company's ATMs, the Boston Globe reported. The branch where the skimmer was placed was not revealed.
Steele believes the incidents took place in early December, but it just came to light over the holiday weekend when the credit union's customers began to report unauthorized activity on their ATM cards.
The QCU shut down its ATM and debit activity on Sunday in light of the activity, the Globe said.
QCU is asking all its customers to check their card usage and said any losses will be reinstated into customer's accounts.
