Fake Photo Files Are Attacking Hotels. What Travelers Should Know

Microsoft Threat Intelligence has identified an active cyber attack campaign targeting hospitality organizations in Europe and Asia. The attackers are sending files that appear to be photo archives (ZIP files) but actually contain malicious software. When hotel staff open these files thinking they are viewing images, the hackers install hidden software that gives them ongoing access to the hotel's computer systems. This affects travelers who book rooms or stay at hotels in Europe and Asia. If a hotel's systems are compromised, your personal information could be at risk. This includes your name, address, phone number, email, credit card details, and passport information that you provide when making a reservation or checking in. The attackers gain persistent access to hotel systems, meaning they can continue stealing information over time.

Here is what you should do to protect yourself:

1. Monitor your credit card statements closely after staying at hotels, especially in Europe and Asia. Look for any unauthorized charges.
2. Consider using a credit card instead of a debit card for hotel bookings, as credit cards offer better fraud protection.
3. Check your credit report for any suspicious activity if you have stayed at hotels in these regions recently.
4. Be cautious about how much personal information you share with hotels. Only provide what is absolutely required.
5. Enable transaction alerts on your credit cards so you are notified immediately of any charges. For long-term protection when traveling, consider using virtual credit card numbers for hotel bookings if your card issuer offers this feature. These temporary numbers protect your actual card details. Keep copies of your important documents separate from the originals you provide to hotels. After international travel, monitor your accounts extra carefully for at least three months. Being proactive about protecting your financial information while traveling reduces your risk of fraud.
