The U.S. Federal Trade Commission has filed a lawsuit against hotel operator Wyndham Worldwide and three of its subsidiaries after three data breaches at Wyndham hotels in less than two years, the agency announced Tuesday.
The three breaches, in 2008 and 2009, led to millions of dollars in fraud losses and the export of hundreds of thousands of customers’ payment card information to an Internet domain address in Russia, the FTC said in a press release.
Wyndham failed to take appropriate security measures to protect customers’ personal data, the FTC alleged. In some cases, Wyndham stored customers’ payment card information in clear text, the agency alleged.
The FTC has asked the U.S. District Court for the District of Arizona to order Wyndham to stop deceiving customers about its information security practices and to order Wyndham to refund lost money to customers.
Wyndham’s security practices were unfair and deceptive and violated the FTC Act, the agency alleged.
Wyndham “cooperated fully” with an FTC investigation into the breaches, the company said in a statement.
“At the time of these incidents, we made prompt efforts to notify the hotel customers whose information may have been compromised, and offered them credit monitoring services,” the company added. “To date, we have not received any indication that any hotel customer experienced a financial loss as a result of these attacks.”
Since the breaches, Wyndham has made “significant enhancements” to its information security practices, the company said.
Wyndham regrets the FTC’s decision to pursue a lawsuit and will defend against the claims “vigorously,” the company added.
Wyndham and its subsidiaries license the Wyndham name to approximately 90 independently owned hotels. Wyndham hotels also include Ramada, Super 8, Days Inn and Howard Johnson.
Since 2008, the Wyndham Hotels and Resorts website has said, “We recognize the importance of protecting the privacy of individual-specific (personally identifiable) information collected about guests, callers to our central reservationcenters, visitors to our Web sites, and members participating in our Loyalty Program.”
But repeated security failures exposed consumers’ personal data to unauthorized access. Wyndham and its subsidiaries failed to take security measures such as complex user IDs and passwords, firewalls and network segmentation between the hotels and the corporate network, the agency alleged.
Wyndham also allowed improper software configurations resulting in the storage of sensitive payment card information in clear readable text.
Each Wyndham-branded hotel has its own property-management computer system to handle payment card transactions, the FTC said. Each system stores payment card account numbers, expiration dates, and security codes.
In the first breach, in April 2008, intruders gained access to a Phoenix Wyndham-branded hotel’s local computer network and the corporate network of Wyndham Hotels and Resorts. The intruders were able to install so-called memory-scraping malware on numerous Wyndham-branded hotels’ property management system servers.
The breach gave the intruders access to the corporate network of Wyndham’s Hotels and Resorts subsidiary, and the property management system servers of 41 Wyndham-branded hotels, the FTC said. The breach led to the compromise of more than 500,000 payment card accounts, with many account numbers exported to a domain registered in Russia, the FTC said.
After the first breach, Wyndham failed to fix the security vulnerabilities and failed to use reasonable measures to detect unauthorized access, the FTC said.
Then, in March 2009, intruders again gained unauthorized access to Wyndham Hotels and Resorts’ network, using similar techniques as in the first breach, the agency said. Intruders installed memory-scraping malware and reconfigured software at the Wyndham-branded hotels to obtain clear text files containing the payment card account numbers of guests. Intruders were able to access information on more than 50,000 payment card accounts at 39 Wyndham-branded hotels and use the accounts to make fraudulent charges, the FTC said.
Later in 2009, intruders again installed memory-scraping malware and thereby compromised Wyndham Hotels and Resorts’ network and the property management system servers of 28 Wyndham-branded hotels. The intruders were able to access information for approximately 69,000 consumer payment card accounts and again make fraudulent purchases on those accounts.
