Marriott International has disclosed that fewer records were stolen in the Starwood cyber breach than previously thought. The hotel chain warned in September 2018 that up to 500 million guest records had been compromised in a massive data hack. That figure has now been revised, with Marriott saying that up to 383 million booking records had in fact been taken, along with 5.25 million unencrypted and 20.3 million encrypted passport numbers. In addition to the passport numbers, the hotel chain estimated that 8.6 million encrypted payment card numbers were stolen, most of which would have expired by November.
