What happened
In July 2024, a threat actor gained access to the hotel management platform Otelier and retrieved customer data from well-known hotel brands including Marriott, Hilton, and Hyatt. The data included 437k customer email addresses (a further 868k generated email addresses from the booking.com and Expedia platforms were not loaded into HIBP), names, physical addresses, phone numbers, booking information related to travel plans, purchases recorded by the platform and in a small number of cases, partial credit card data.
What data was exposed
- Email addresses
- Names
- Partial credit card data
- Phone numbers
- Physical addresses
- Purchases
- Travel plans
What to do right now
- Watch your card and bank statements. Set up transaction alerts, and consider a card freeze or replacement if the exposure included full card numbers.
- Be alert for smishing and SIM-swap attempts. Treat unexpected texts and "carrier" calls with suspicion; add a PIN/port-freeze with your mobile carrier.
- Watch for targeted phishing mail. A leaked home address makes postal and doorstep scams more convincing.
- Expect convincing phishing emails. Attackers use breached details to write personalized emails. Be suspicious of any message referencing this service.
- Check your other accounts on Have I Been Pwned. Your email address may appear in other breaches you don't know about yet.
- Monitor the apps you use going forward. Clearly watches the breach record for the companies behind your apps and alerts you the moment one appears.
