What to do now
It depends on what was exposed, so these steps follow the list above.
If your contact details were exposed
- Expect more spam, scam calls and phishing. Do not click links or open attachments in messages you did not expect.
- If a message mentions this breach, do not reply. Go to the organisation's own website or app instead of using a link in the message.
Whatever was exposed
- Check which other breaches include your own email address and phone number.
- Keep an eye on your accounts for a few months. Breached data is often used long after the breach.
- If you think someone is using your details, report it to the organisation and to your national cyber crime reporting service.
Check your own exposure
- Password leak check: find out whether a password has appeared in a breach. The password never leaves your browser.
- Free domain security scan: grade the email, DNS and website security of a domain you own.
