Hyatt Hotels tells customers to check credit cards amid malware hacking fears

Company with hotels in 52 countries warns customers after malware was discovered in payments system in November

Global hotel chain Hyatt has advised customers to review their card statements after it found malicious software on the computer system that processes customer payments, raising the possibility that hackers may have obtained credit card numbers or other sensitive information.

The company has not said if any customer data was stolen. Hyatt spokeswoman Stephanie Sheppard said in an email the malware was discovered on 30 November but did not say why the company waited more than three weeks to report the discovery on Wednesday.
