During the Cambridge Analytics scandal, 8 million personal data of Facebook social network users were sold. It calmed down a bit when we were greeted by something even worse - 553 million personal Facebook data were sold!
Namely, for this weekend, hackers posted personal data of 553 million Facebook users on one hacker forum for free. These data include telephone numbers, email addresses, name and surname, date of birth, location… of users from 106 countries. Specifically, 32 million users from the USA, 11 million from the UK and 6 million from India were hacked.
Security experts checked this data by comparing phone numbers with Facebook profile identification numbers on a single sample. They also confirmed by comparing the email address with the part of the phone number that appears when the user requests a password reset. Facebook has not yet officially announced this problem, but we know that the data date from 2019.
"These are outdated data dating back to 2019. The problem was found and fixed in 2019, ”Liz Bourgeois from Facebook stated on her Twitter account. Despite the fact that the data is outdated, for most users it is still valid and can be used for various malicious purposes.
Has your data been leaked?
To find out if your data was leaked in this (or any other) attack, follow these steps: 1. Go to haveibeenpwned.com 2. In the field in the middle of the screen, enter the email address or mobile number you use on Facebook 3. Press the "Pwned?" Key
You will now see all the databases where your email address or mobile number is located. These bases have been sold / leaked online from various attacks in the past. This service inserts these databases into its own so that users can check if they are in them. Note: "Have I been pwned" is a serious and transparent service. It does not store your data that you enter in that field on the site, it only compares it with the database.
How look when you data is safe
And how look when your mail (and other data) is listed in some unwanted place
When you scroll down you can see where is you data listed
From this case it must be clear to us that no matter how much data has been protected, we see that unwanted things are happening. What we can do about the security of our data is that we have different access codes on each account and that we have active 2fa protection. In addition, we absolutely never click on the link that arrives in our mail, as well as do not open attachments, unless we have asked for them.
