NEW YORK — A security breach at a major online retailer has prompted the company to cancel a planned $100 million gift card for customers, a major retailer said Monday.
The gift card, a purchase card that can be used on Amazon.com, was supposed to go to customers at retailers including Walmart, Costco and Best Buy, the company said in a statement.
But the gift card was mistakenly sold to Amazon.
Com, the retailer said.
It did not say who bought the card.
The incident comes after security breaches at online retailers have prompted the retail industry to update security procedures and make the stores’ systems more secure.
The company’s chief security officer, Brian Cook, said the breach was caused by an unauthorized user who gained access to its cloud-based systems and that it is investigating.
The breach was not connected to a cyberattack that disrupted Amazon.org and other major retailers, Cook said.
Amazon.com did not immediately respond to a request for comment.
The retailer said the card was a gift card that could be used for Amazon.gov purchases, such as Prime membership and Prime Day gifts.
The card had a minimum $100 minimum balance and required a $100 payment to unlock the benefits, it said.
The $100 gift card would be honored at all Amazon.net retail locations, Cook added.
The store was not immediately available for comment Monday.
A security incident at a company like Amazon can have a ripple effect on other online retailers.
Earlier this month, a hacker called “Shadows” gained access into a warehouse at Amazon.
It was the first breach of Amazon’s network, and the company had not released details about the hack.
Amazon said last month that hackers had infiltrated the company’s network for several months, and that its security was not at the same level as its competitors.
The theft affected more than 1.5 million customers.
Amazon also announced in January that it was suspending its Prime membership program.
