A hacker is selling the personal details of over 130 million hotel guests for 8 Bitcoin ($56,000) on a Chinese Dark Web forum. The breach was reported today by Chinese media after several cyber-security firms spotted the forum ad [1 [sina.com.cn], 2 [sohu.com], 3 [qq.com], 4 [wallstreetcn.com]].

The seller said he obtained the data from Huazhu Hotels Group Ltd [huazhu.com] (Huazhu from hereafter), one of China's largest hotel chains, which operates 13 hotel brands across 5,162 hotels in 1,119 Chinese cities. According to a description the hacker posted online, the stolen data is 141.5GB in size, contains 240 million records, with information on roughly 130 million hotel guests that stayed at one of Huazhu hotels.

The following user data is believed to be sold online: official website registration information (ID card number, mobile phone number, email address, login password); check-in registration information (customer name, ID card number, home address, birthday), and booking information (name, card number, mobile phone number, check-in time, departure time, hotel ID number, room number).

[...] The data appears to be from customers who stayed at any of Huazhu's hotel brands —Hanting Hotel, Grand Mercure, Joye, Manxin, Novotel, Mercure, CitiGo, Orange, All Season, Starway, Ibis, Elan, Haiyou.

They said the cause of the breach appears to be a mistake on the part of the Huazhu's development team, who seem to have uploaded copies of their database on a GitHub account.
