Post leaked personal data from more than 500 million facebook users

Facebook is once again in the spotlight when it comes to personal data leakage, as information published this Saturday afternoon by Business Insider shows that leaked personal data from more than 500 million users in some 106 countries, including Spain, has just been published on an Internet hacking forum, and is now widely available for free.

Personal data includes phone numbers, user IDs, dates of birth, full names, and even in some cases up to email addresses, among others.

Those affected could become victims of phishing and scams

All of this personal data now published is two years old, obtained before the company closed a security breach in August 2019. However, according to a series of inquiries that the publication has been able to make with a sample, this data is still valid to this day.

For Alon Gal, chief technology officer of cybercrime intelligence firm Hudson Rock, who discovered the publication of personal data leaked in the aforementioned forum today, this data could allow bad actors to act against affected users through phishing or scamming.

More specifically, it notes that:

A database of that size containing private information, such as phone numbers of many Facebook users, would certainly lead to bad actors taking advantage of data to carry out social engineering attacks [or] hacking attempts

Gal has already been aware of the existence of the leaked data since this last January, when a user of the same hacking forum announced the existence of an automated bot capable of offering phone numbers of millions of Facebook users, a bot that by the way came to be informed also by Motherboard, further verifying the legitimacy of the data it offers.

At this point, Gal notes that Facebook can no longer do much to help affected users, as the filtered data is now given users with rudimentary knowledge for their access.

In this sense, the only possibility available by Facebook is to notify the affected users so that they can take letters in the matter and take steps to avoid possible problems as a result of the use of their data.
