Marriott International announced a new and fairly significant data breach, the hotel chain’s second in under two years and informed past guests and members of its guest-loyalty program on Tuesday.

The security breach involved 5.2 million records.

The hotelier says that guest names, addresses, phone numbers, dates of birth, loyalty account information, and loyalty program information for partner companies such as airlines may have been included.  The company said that an investigation is still underway but it does not believe credit card or other critical information was breached.

The breach was noticed by Marriott at the end of February and believes it started in mid January. The intruders used the login credentials of two employees employed at a franchised property.

Marriott did not say whether the two were under suspicion in the investigation, which is being conducted by the Federal Bureau of Investigation, nor did it say whether the two are still employed by the property.

In 2018, the Starwood Hotels and Resorts database was breached and intruders were able to mine 383 million guest records at that time.  Starwood had already merged with Marriott when that took place.

Marriott’s response to the break-in was low key.

“Marriott also remains committed to further strengthening its protections to detect and remediate incidents such as this in the future,“ it said in a statement.
