Over the last week, multiple reports have linked the Chinese government to the massive hack of Marriott that exposed 500 million individuals' personal data. That included the passports and credit card details of customers at Starwood hotels, alongside a trove of other sensitive information.
Reuters was the first to cite people familiar with the investigation into the breach, followed by the New York Times late Tuesday. The reports indicated the techniques used by the hackers were similar to those previously associated with Chinese cyberespionage agents. The Times also cited sources who claimed the Marriott attack was part of the same operation that led to the massive breach of the Office of Personnel Management (OPM). The latter saw the personal data of 21.5 million Americans, including many of those with top secret security clearance, stolen.
