In a post on a hacker forum, a hacker calling themselves “ChinaDan” claimed the stolen databases held “information on 1 billion Chinese national residents and several billion case records, including: name, address, birthplace, national ID number, mobile number, all crime/case details.”
Zhao Changpeng, CEO of cryptocurrency exchange Binance, said the company had upgraded its user-verification protocol after spotting the sale of data belonging to 1 billion residents of an unspecified Asian country.
