Up to 9.4 million passengers' info leaked in Cathay Pacific breach

Hong Kong airliner Cathay Pacific announced Wednesday it discovered that up to 9.4 million passenger records were breached this spring, per The Guardian.

Why it matters: Information including names, dates of birth, credit card numbers, passport numbers, identity card numbers, and historical travel information was accessed by attackers — and all that could be cross-referenced with other data repositories to conduct identity theft.
