20m China Jiangxi mobile customer

In 2010, a massive data breach occurred at Jiangxi Mobile, a Chinese telecommunications company. The breach exposed the personal information of over 20 million customers, including their names, addresses, phone numbers, and identity card numbers.

The leak was discovered in June 2010 and was one of the largest data breaches in history. The stolen data was sold on the black market and was used by criminals to commit identity theft and other crimes. The breach had a significant impact on Jiangxi Mobiles reputation and led to the company being fined by the Chinese government.
