Costco discloses data breach after finding credit card skimmer
2021-11-12 15:11

Costco Wholesale Corporation has warned customers in notification letters sent this month that their payment card information might have been stolen while recently shopping at one of its stores.

Costco discovered the breach after finding a payment card skimming device in one of its warehouses during a routine check conducted by Costco personnel.

"We recently discovered a payment card skimming device at a Costco warehouse you recently visited," Costco told potentially impacted customers in breach notification letters.

"If unauthorized parties were able to remove information from the device before it was discovered, they may have acquired the magnetic stripe of your payment card, including your name, card number, card expiration date, and CVV," Costco revealed.

The retailer advised the customers to monitor their bank and credit card statements for fraudulent charges and report suspicious transactions to relevant financial institutions.

Data breach notification letters sent to affected individuals did not disclose the total number of impacted customers or the warehouse location where the skimmer device was found.
