'Malicious' data breach impacting customers' bank account details


In September 2018, the company disclosed that the personal and financial details of customers making or amending bookings had been compromised affecting about 380,000 transactions after hackers breached the company's website and mobile app during a two-week period. The incident involved diverting user traffic from the company's website to a fraudulent site and through this false site, customer details were harvested by the attackers.

Personal data of approximately 500,000 customers were compromised by the bad actors who were believed to have begun to attack the company in June 2018.

The company confirmed that the stolen data did not include travel or passport details but according to the company's CEO included "name, email address, credit card information - that would be credit card number, expiration date and the three digit [CVV] code on the back of the credit card".

In October 2020, the UK's Information Commissioner's Office fined the company £20 million for failing to protect customer's data (its biggest penalty of this type to date).
