In 2020, a massive data leak occurred on the Chinese microblogging platform Weibo. The leak exposed the personal information of over 503 million users, making it one of the largest data breaches in history.

Hackers gained access to Weibos database and stole a trove of data, including names, phone numbers, email addresses, birthdates, and even user passwords. The stolen data was then sold on the dark web, putting the security of millions of Weibo users at risk.
