A hacker suspected to be operating out of China has been seen peddling the data of around 200 million Japanese users on an underground cybercrime forum. The data appears to have been assembled by hacking up to 50 smaller Japanese sites and put up for sale as one giant archive in December 2017. FireEye believes the data is authentic and not forged because it contains data on users whose personal info had been leaked in other breaches, but also data for new users. The price for the entire archive is ..1,000 CNY ($150.96 USD)
