https://haveibeenpwned.com/ has been updated for this data breach.
It's now also possible to search for compromised phone numbers for this particular Facebook data breach in HaveIBeenPwned.
Format to use when searching a phone number: <country code><phone number>, e.g 31612345678.
A few remarks on this:
- with 06-phone numbers, the first zero should be omitted
- the '+' in the country code is not a requirement but can be included as well.
I have tested the above for accuracy, I've been a victim of this as well.
