The leaked data was found by Alon Gal, the Chief Information Officer at cybercrime intelligence company Hudson Rock who posted the details on his Twitter account.
The leak includes the following information:
- Phone Numbers
- Facebook IDs
- Birth Dates
- Full Names
- Email Addresses
- Account Creation Date
The data was accessed back in 2019, and while Facebook has stated that it is ‘old data’ and that the issue was ‘fixed in August 2019’, the social media giant hasn’t provided any support or guidance for affected users at the current time.
How to check if your Facebook data has been leaked
Luckily, there are third-party agents such as Troy Hunt on hand to provide support, and a way to check if your Facebook account is one of the 533 million accounts whose data was accessed. Troy Hunt is a Microsoft Regional Director and MVP who runs the haveibeenpwned.com website where people can check email addresses and phone numbers to see if their accounts have been hacked.
All you need to do is head over to https://haveibeenpwned.com/, enter the phone number from your Facebook account and press Enter or ‘pwned’, after which the results will appear. You’ll hopefully get the news that your data is safe, after which you should also check your email address/addresses.
If your phone number or email address comes up as one of the affected Facebook accounts, or any other data breaches, it’s a good idea to change your login details, enable 2FA authentication, and look into a quality password manager such as LastPass, Bitwarden, Dashlane, etc.
Considering the sheer scope of the data breach and the broad availability of the information, it’s yet another sign that Facebook cannot be trusted with the amount of personal data it mines from our social media accounts. This isn’t the first time, and it almost certainly won’t be the last time that Facebook suffers a data breach and doesn’t accept responsibility.
