Has my email been breached?
Understanding exposure — and what it actually means
Most people have at least one email address that has appeared in a data breach. The real issue isn't whether it's happened — it's what happens next.
Data breaches don't just expose email addresses — they often expose passwords, patterns, and behaviours.
How breaches happen
Companies store your data. Sometimes they are compromised. When that happens, databases are leaked or sold.
- Login credentials
- Email addresses
- Password hashes (sometimes cracked)
- Personal data
Why it matters
Attackers use breached data to:
- Attempt login reuse attacks
- Target phishing campaigns
- Build profiles of individuals and businesses
The key risk
If you reuse passwords — even once — a breach elsewhere can become access to your systems.
