When companies are breached, criminals use stolen data to craft more convincing phishing attacks.


Why Breached Data Is Dangerous

Attackers may have:

  • Your email

  • Past passwords

  • Address or phone number

This makes phishing emails feel personal.


Protection Steps

  1. Change breached passwords

  2. Use unique passwords

  3. Monitor for suspicious emails
