Hyatt announced Wednesday that it has found malware in its payments systems.
According to the announcement, it is unclear if the malware was able to take credit card information from customers. It's also unclear how many customers are affected.
However, Hyatt is warning its customers to keep an eye on their credit card statements for unauthorized charges.
Hyatt says it's still investigating the issue and will provide updates on this site.
Here's the full statement from Hyatt:
