In the same way as for passwords.
- nikisweeting 6y agoNah because you can iterate through all phone numbers pretty quickly.
- GoblinSlayer 6y agoIterating through passwords is not slower. And in practice there's no need to iterate, you just download the leak and see phone numbers there.
- nikisweeting 6y agoAgreed, just saying it's especially trivial for phone numbers.
- fX0rObfoMN4 6y agoPhone numbers are only 10 digits. That is only 10 billion combinations. For SHA1 which pwned passwords uses that it should only take a couple seconds on a decent system. Even with SHA256 it could be done in like a minute.
