British Air data breach

Between Aug. 21 and Sept. 5, a data breach involving British Airways' smartphone app exposed the passport numbers and credit card information of thousands of customers. It is estimated that the personal information of more than 300,000 people was stolen.

Only the accounts of customers who used the app to purchase or change flights were included in the breach. Accounts of people making purchases or changes on the airline's website (www.ba.com) were not exposed.
