According to the BBC, Easyjet first became aware of the attack in January.
Low-cost airline Easyjet says they have been exposed to a highly sophisticated cyber attack, the BBC reports.
The attackers must have stolen email addresses and travel details from around nine million customers and gained access to 2208 customers’ credit card details.
According to the BBC, Easyjet first became aware of the attack in January and customers who had their credit card details stolen should have been notified in April.
The situation is now being investigated by both Easyjet and UK authorities. Easyjet says they will have notified all nine million affected customers by May 26.
According to the airline, there is no evidence that the leaked information has been misused, but they warn that customers should be aware of the risk of, for example, phishing attacks that appear to come from Easyjet.
