1. Report: Marriott chain cyberattack done by Chinese hackers

The cyberattack that exposed the personal information of 500 million guests of Marriott's Starwood hotel chain was done by the same Chinese hackers who targeted health insurers and security-clearance files of millions more Americans, The New York Times reported Tuesday, citing two people briefed on the investigation. The hackers were suspected of working for China's Ministry of State Security in an intelligence-gathering effort. The tracing of the Marriott breach came as the Trump administration is preparing to indict Chinese hackers working for the country's intelligence services and military, four government officials told the Times. The administration also reportedly plans to declassify intelligence reports on a Chinese effort to compile a database of executives and government officials with security clearances that dates to at least 2014.
