Leaked; 4.5 billion pieces of personal information, the failure of Beijing's cybersecurity

Incidents of personal information being sold on the internet occasionally occur in China. However, recently, it is suspected that 4.5 billion pieces of personal data in the e-commerce or logistics industry have been leaked. A network security professional under the pseudonym of Bing Chen suspects an insider of leaking data. Why is the CCP's cyber security monitoring ineffective at this time?

Chinese media reported that personal information leaked on the "dark web" included real names, phone numbers, and addresses. "Dark Web" uses encrypted transmission, a technical means to provide users access to anonymous internet information.
The incident happened on the evening of February 12. The social platform Telegram suddenly forwarded many links to a privacy query robot. It is said that this robot leaked 4.5 billion pieces of personal information in China, with data of up to 435 GB, suspected of e-commerce and fast delivery industry.
