If you want to know if your phone number was among the 553 million exposed by Facebook, there are a few ways to find out. The “Have I Been Pwned?” website is one such resource, as is a dedicated page from “The News Each Day” or the “Have I Been Facebooked?” website, but we cannot promise that these, too, will not record your phone number for unclear reasons.
Last weekend, 553 million Facebook users had their data leaked to a hacker forum. Despite including personal data such as phone numbers, full name, birthdate, email addresses, and more, Facebook isn’t notifying those affected.
Facebook is yet to release a formal announcement about the case. Liz Bourgeois, Facebook’s solution communications manager, confirmed that “this is old data that was already posted on in 2019” and that the flaw was fixed in August 2019, but that didn’t prevent a hacker from uploading 20GB of data from 553 million people to the Internet.
If you want to see if your phone number has been leaked, you can either download the 20GB archive as a torrent file or use one of the many websites that can tell you if your phone number is included in the leak.
There are at least three websites where you can enter your phone number for that purpose. The most trusted of the bunch is haveibeenpwned.com, managed by Troy Hunt, an Australian Microsoft regional director and Microsoft MVP for developer security.
It is important to note that we cannot promise that these websites will not record your phone number. Putting your phone number on an unknown website can cause you problems in the future. And, if your phone number was also part of the breach, be wary of any spam or SMS messages you may receive.
