It turns out that the personal data of more than 500 million Facebook users has been posted to the hacker forum. These data include name, phone number, email address, location information, background, etc.
Information such as name, phone number, and biography leaked
According to Business Insider, beginner-level hacker forum users have posted personal information about a total of more than 533 million Facebook users in more than 106 countries. Anyone can view this information for free.
Of the 533 million leaked user data, about 32 million are from US users, about 11 million are from the UK, and about 6 million are from India. The article does not say how much data of Japanese users is included.
The data posted included phone numbers, full names, location information, birthdays, biography, and, for some users, email addresses.
May lead to crimes such as spoofing
When Business Insider collated some of the leaked data with Facebook user data (what the editorial department actually confirmed), it was said that the phone numbers did match. It also reports that the email address included in Facebook’s password reset function could be verified.
Aaron Gull, CTO of cybercrime intelligence company Hudson Rock, who discovered a huge amount of Facebook user information leaked on April 3, local time, said this personal information , It warns that it may lead to crimes such as theft of login information by spoofing.
All 533,000,000 Facebook records were just leaked for free.
This means that if you have a Facebook account, it is extremely likely the phone number used for the account was leaked.
I have yet to see Facebook acknowledging this absolute negligence of your data. Https://t.co/ysGCPZm5U3 pic.twitter.com/nM0Fu4GDY8

Leaked data, anyone can view
Gull first noticed Facebook’s personal data leak in January 2021. In the same hacker forum where he discovered his personal information this time, a user was advertising in a bot that he would provide the phone numbers of millions of Facebook users for a fee. The US media Motherboard also noticed the existence of this bot and reported that the personal data that was partially released at that time was genuine.
And this time, all the data has been released for free on the hacker forum. Anyone with some skill can view it.
Repeated Facebook information leak problem
This is not the first time that an information leakage problem has occurred on Facebook. In 2016, the personal information of up to 87 million people was leaked to Cambridge Analytica, a data analysis consulting company, and it became a big problem involving the US government.
After that, the data of 29 million users was leaked in 2018, the phone numbers of nearly 420 million users were leaked in 2019, and the problem of personal information leakage was discovered in 2020.
