Hyatt Corp. is alerting customers about another credit card breach at some hotels. Hyatt said its cyber security team discovered signs of unauthorized access to payment card information from cards manually entered or swiped at the front desk of certain Hyatt-managed locations between March 18, 2017 and July 2, 2017. In late 2015, Hyatt announced that for about four months that year hackers had gained access to credit card systems at 250 properties in 50 different countries. This time, the breach appears to have impacted 41 properties across 11 countries.”]
