What exactly is a data breach?
A data breach happens when personal or private information gets exposed, stolen or copied without permission. These security incidents can result from cyber attacks on websites, apps or any database where people's personal information resides. A data breach can also happen accidentally, like if someone's login credentials get posted publicly.
Why am I in this breach?
Hackers often target massive companies with millions of users to get as much personal information and credentials as possible.

Hackers combined the passwords and email addresses from many data breaches into one single list. 5. A data aggregator was breached. These companies collect your in...
How do I know these emails are from Firefox, not a hacker?
Check the email address in the sender's field. Mozilla Monitor emails will always come from breach-alerts@mozilla.com. Firefox will never ask you to enter your login credentials or password in an email. Most online services won't ask you to enter your login info directly from an email. If they do, you should instead go directly to their website to sign in.
