Marriott CEO: Source of cyberattack still unknown
Marriott International CEO Arne Sorenson testified to a U.S. Senate subcommittee Thursday, apologizing for the massive data breach that involved 383 million guest records in the Starwood hotels reservation system.
Appearing before the Senate Homeland Subcommittee Hearing on Data Breaches, Sorenson was asked if he believes China was responsible for the attack.
"The short answer is, we don't know," he said. "And I feel quite inadequate about even drawing inferences from the information we've obtained."
Sorenson says Marriott has given the FBI information about IP addresses and malware tools used in the Starwood system so its investigators can try to determine the cause.
"We've simply been focused on making sure the door is closed and communicating with our customers," Sorenson says.
