Facebook: 533 million phone numbers in the wild, including that of Mark Zuckerberg
But it's not just numbers and e-mail addresses, here is all the data that can be found:
- Telephone numbers,
- Facebook identifiers,
- full names,
- the addresses,
- dates of birth,
- biographies,
- and, in some cases, email addresses
How can I verify the presence of my number?
We have identified two safe tools to verify the presence of your number:
- I only see you for FR numbers
- haveibeenpwned.com
Regarding the last site on the list, as Numerama specifies, enter your phone number, without the 0, but with the code of your country: +33 for Spain, +41 for Switzerland or +32 for Belgium. For example: + 33XXXXXXXXX.
My number is in the database, what should I do?
We will have to be even more vigilant than usual. You will certainly be targeted by well-targeted phishing attacks. You can also change the number by contacting your mobile operator.
Our best advice is toenable two-factor authentication as soon as possible. It adds, in addition to the password, a new authentication step, such as a message with a code, the use of a security key or an authentication application. If someone tries to access your account after having hacked your password, then they should normally be blocked by the confirmation of your identity, which will take place on your smartphone.
