If you've stayed in a Marriott hotel recently, then your personal data might have been stolen. The affected hotels are managed by the White Lodging Services Corporation, a hotel franchise firm.
Security researcher Brian Krebs uncovered last year's breach, which occurred on January 31, 2014. White Lodging Services Corporation acknowledged the breach and revealed that food and beverage outlets at 14 locations had card-tracking malware installed on their point-of-sale systems.
The malware was stealing customer data for nine months. Now, it looks like the same thing is happening again. Want a better look at last year's breach? This video will help.
Sources in the banking community have told Brian Krebs that many of the same locations may be affected.
