Marriott Announces Customer Data Breach for 5.2 Million Guests

Marriott International (NASDAQ: MAR), the largest hotel operator in the world, said in a statement on Tuesday that one of its apps had been hacked and the information for as many as 5.2 million rewards members had been breached.

The company said it noticed in late February 2020 that a certain app that allows owned and franchised hotels to access customer preferences had unusually high usage from a franchised property in Russia. After revoking credentials of two employee logins that had been used to access the information and upon further investigation, Marriott said it appeared that the activity had been going on since the beginning of January 2020.
