Best Buy, Kmart Latest Victims Of Chat Service Cyber Breach

You can add retailers Best Buy and Kmart to the list of companies that have been impacted by a cybersecurity breach at a third-party chat service that potentially exposed information from thousands of credit cards.

Last week chat service provider [24]7.ai announced that its system was a victim of a security breach in September and October 2017 where hackers were able to gain access to payment information for [24]7.ai's business clients, according to a story on the Threatpost website.

Following last week's announcement, Delta Airlines and retailer Sears disclosed that they used the [24]7.ai service and that they had been impacted by the cyber breach.

Best Buy said it believed that only a "small fraction" of its customers' payment card information may have been compromised by the incident. Sears said previously that the attackers gained access to information from less than 100,000 customers' credit cards. Kmart is owned by Sears Holdings.
