Delta has uncovered a data breach affecting its customers dating back to last fall.
The airline, which counts MSP Airport as one of its major hubs, says a company that provides online chat services for Delta and other companies was compromised in a cyber incident.
The breach of 7.ai occurred between Sept. 26 and Oct. 12, 2017, during which "certain customer payment information for 7.ai clients, including Delta, may have been accessed."
The company says no other personal information, such as passports, government IDs, security or SkyMiles information was impacted.
"At this point, even though only a small subset of our customers would have been exposed, we cannot say definitively whether any of our customers' information was actually accessed or subsequently compromised," Delta said.
Delta is launching a dedicated website, delta.com/response, on Thursday to provide regular updates relating to the beach.
"In the event any of our customers' payment cards were used fraudulently as a result of the 7.ai cyber incident, we will ensure our customers are not responsible for that activity."
