MITRE

  

Here first we will go to this website https://haveibeenpwned.com 

Then we prepare the email or phone number that we want to investigate 

Here we put the phone number and then pressed Enter and indeed we can see at the bottom that it tells us that data or information has been leaked once and indeed this number receives a lot of messages and random numbers on WhatsApp

Here we will try another number and we will be able to see that there is a green mark telling us that everything is good and the data for this number has not been leaked

It is the same thing We can put the phone number or put the email on the red color which indicates that this is not safe and the data for this thing was leaked in the process of a data breach whether it was an email or a phone number and the green color indicates that everything is fine
