Hilton Acknowledges Credit Card Breach

Two months after KrebsOnSecurity first reported that multiple banks suspected a credit card breach at Hilton Hotel properties across the country, Hilton has acknowledged an intrusion involving malicious software found on some point-of-sale systems.

hiltonAccording to a statement released after markets closed on Tuesday, the breach persisted over a 17-week period from Nov. 18, 2014 to Dec. 5, 2014, or April 21 to July 27, 2015.

“Hilton Worldwide (NYSE: HLT) has identified and taken action to eradicate unauthorized malware that targeted payment card information in some point-of-sale systems,” the company said. “Hilton immediately launched an investigation and has further strengthened its systems.”

Hilton said the data stolen includes cardholder names, payment card numbers, security codes and expiration dates, but no addresses or personal identification numbers (PINs).

The company did not say how many Hilton locations or brands were impacted, or whether the breach was limited to compromised point-of-sale devices inside of franchised restaurants, coffee bars and gift shops within Hilton properties — as previously reported here.

The announcement from Hilton comes just five days after Starwood Hotel & Resorts Worldwide — including some 50 Sheraton and Westin locations — was hit by a similar breach that lasted nearly six months.

Starwood and Hilton join several other major hotel brands in announcing a malware-driven credit card data breach over the past year. In October 2015, The Trump Hotel Collection confirmed a report first published by KrebsOnSecurity in June about a possible card breach at the luxury hotel chain.

In March, upscale hotel chain Mandarin Oriental acknowledged a similar breach. The following month, hotel franchising firm White Lodging allowed that — for the second time in 12 months — card processing systems at several of its locations were breached by hackers.

Readers should remember that they are not liable for unauthorized debit or credit card charges, but with one big caveat: the onus is on the cardholder to spot and report any unauthorized charges. Keep a close eye on your monthly statements and report any bogus activity immediately. Many card issuers now let customers receive text alerts for each card purchase and/or for any account changes. Take a moment to review the notification options available to you from your bank or card issuer.

Banks: Card Breach at Hilton Hotel Properties

Multiple sources in the banking industry say they have traced a pattern of credit card fraud that suggests hackers have compromised point-of-sale registers in gift shops and restaurants at a large number of Hilton Hotel and franchise properties across the United States. Hilton says it is investigating the claims.

hiltonIn August, Visa sent confidential alerts to numerous financial institutions warning of a breach at a brick-and-mortar entity that is known to have extended from April 21, 2015 to July 27, 2015. The alerts to each bank included card numbers that were suspected of being compromised, but per Visa policy those notifications did not name the breached entity.

However, sources at five different banks say they have now determined that the common point-of-purchase for cards included in that alert had only one commonality: They were all were used at Hilton properties, including the company’s flagship Hilton locations as well as Embassy Suites, DoubletreeHampton Inn and Suites, and the upscale Waldorf Astoria Hotels & Resorts.

In a written statement, a Hilton spokesperson said the company is investigating the breach claims.

“Hilton Worldwide is strongly committed to protecting our customers’ credit card information,” the company said. “We have many systems in place and work with some of the top experts in the field to address data security.  Unfortunately the possibility of fraudulent credit card activity is all too common for every company in today’s marketplace.  We take any potential issue very seriously, and we are looking into this matter.”

As with other recent card breaches at major hotel chains — including Mandarin Oriental and White Lodging properties — the breach does not appear to be related to the guest reservation systems at the affected locations. Rather, sources say the fraud seems to stem from compromised point-of-sale devices inside of franchised restaurants, coffee bars and gift shops within Hilton properties.

It remains unclear how many Hilton properties may be affected by this apparent breach. Several sources in the financial industry told KrebsOnSecurity that the incident may date back to November 2014, and may still be ongoing.
