LINE Pay leaks around 133,000 users’ data to Github, of all places

Smartphone payment provider LINE Pay announced yesterday that around 133,000 users’ payment details were mistakenly published on GitHub between September and November of this year.

Files detailing participants in a LINE Pay promotional program staged between late December 2020 and April 2021 were accidentally uploaded to the collaborative coding crèche by a research group employee.

Among the leaked details were the date, time, and amount of transactions, plus user and franchise store identification numbers. Although names, addresses, telephone, credit card number and bank account were not shared, the names of the users and other details could be traced with a little effort.

The information, which consisted of over 51,000 Japanese users and almost 82,000 Taiwanese and Thai users, was accessed 11 times during the ten weeks it was available online.

The information has since been removed and LINE said users have been notified. The fintech division of the communication app company issued an apology and promised to better train staff.
