If you’ve used a credit card at a Hyatt Hotel or Hyatt-managed facility between August 13, 2015 and December 8, 2015 — for any purpose— you’ll want to be ever more vigilant about checking your credit card statements.  Why? Because hackers breached the payment systems at a staggering number of Hyatt-managed locations during these dates.  The thieves stole payment card information — cardholder name, card number, expiration date and internal verification code.

And the hack wasn’t just of those guests who stayed at a Hyatt hotel.  The credit card information was stolen from people who charged a meal at a Hyatt hotel restaurant or used a Hyatt facility (e.g,, parking, spa).

On January 14th, the Hyatt Hotels Corporation posted a news release on their website outlining the results of their investigation of this breach (newsroom.hyatt.com/news-releases?item=123453).  In that release, Hyatt notes that there are a smaller number of Hyatt locations that were affected beginning on or after July 30, 2015.

Of course, these dates encompass some prime time summer and fall travel so there’s no estimate of how many people were affected.

The Hyatt news release includes a list of the affected Hyatt locations. Hyatt is minimizing the impact but I looked at the list and as I said above, the number of Hyatt locations included is staggeringly large.

That list can be found at: http://www.hyatt.com/protectingour customers.  People with questions can also call a toll free number from 7 a.m. to 9 p.m. Eastern Standard Time to speak with a Hyatt customer service representative.  That number is: 1-877-218-3036 (for the U.S. and Canada).

In its news release, Hyatt says that it worked with law enforcement and the payment card networks to notify them about the breach and to strengthen its systems.

Let’s hope this is true.
