InterContinental Hotels Group (IHG), the parent company for more than 5,000 hotels worldwide including Holiday Inn, says it is investigating claims of a possible credit card breach at some U.S. locations.

Last week, KrebsOnSecurity began hearing from sources who work in fraud prevention at different financial institutions. Those sources said they were seeing a pattern of fraud on customer credit and debit cards that suggested a breach at some IHG properties — particularly Holiday Inn and Holiday Inn Express locations.
Asked about the fraud patterns reported by my sources, a spokesperson for IHG said the company had received similar reports, and that it has hired an outside security firm to help investigate. IHG also issued the following statement:
“IHG takes the protection of payment card data very seriously. We were made aware of a report of unauthorized charges occurring on some payment cards that were recently used at a small number of U.S.-based hotel locations. We immediately launched an investigation, which includes retaining a leading computer security firm to provide us with additional support. We continue to work with the payment card networks.”
“We are committed to swiftly resolving this matter. In the meantime, and in line with best practice, we recommend that individuals closely monitor their payment card account statements. If there are unauthorized charges, individuals should immediately notify their bank. Payment card network rules generally state that cardholders are not responsible for such charges.”
Headquartered in Denham, U.K., IHG operates more than 5,000 hotels across nearly 100 countries. The company’s dozen brands include Holiday Inn, Holiday Inn Express, InterContinental, Kimpton Hotels, and Crowne Plaza.
Card-stealing cyber thieves have broken into some of the largest hotel chains over the past few years. Hotel brands that have acknowledged card breaches over the last year after prompting by KrebsOnSecurity include Kimpton Hotels, Trump Hotels (twice), Hilton, Mandarin Oriental, and White Lodging (twice). Card breaches also have hit hospitality chains Starwood Hotels and Hyatt.
In many of those incidents, thieves planted malicious software on the point-of-sale devices at restaurants and bars inside of the hotel chains. Point-of-sale based malware has driven most of the credit card breaches over the past two years, including intrusions at Target and Home Depot, as well as breaches at a slew of point-of-sale vendors. The malware usually is installed via hacked remote administration tools. Once the attackers have their malware loaded onto the point-of-sale devices, they can remotely capture data from each card swiped at that cash register.
Thieves can then sell that data to crooks who specialize in encoding the stolen data onto any card with a magnetic stripe, and using the cards to purchase high-priced electronics and gift cards from big-box stores like Target and Best Buy.
Readers should remember that they’re not liable for fraudulent charges on their credit or debit cards, but they still have to report the unauthorized transactions. There is no substitute for keeping a close eye on your card statements. Also, consider using credit cards instead of debit cards; having your checking account emptied of cash while your bank sorts out the situation can be a hassle and lead to secondary problems (bounced checks, for instance).
