The dataset, which allegedly contains more than 10 petabytes of sensitive information, is believed by experts to have been obtained from the National Supercomputing Center (NSCC) in Tianjin – a centralized hub that provides infrastructure services for more than 6,000 clients across China, including advanced science and defense agencies.


Sounds really unrealistic. Thousands of dollars is really cheap when it comes to storing 10 pb of data, i mean fucking hell at that price point dude would profit way more by being a cloud storage provider.
It said a preview was available for thousands of dollars but the full database is selling for hundreds of thousands. That seems more realistic for risk & storage/hosting costs.
