What happened
In March 2026, the Colombian fintech company Addi identified unauthorised activity on its platform and advised customers that "it is possible that your personal information may have been compromised". The "pay or leak" extortion group ShinyHunters subsequently claimed responsibility and published a large trove of personal data allegedly obtained from Addi. The data included 34M unique email addres

What to do now
It depends on what was exposed, so these steps follow the list above.
If identity documents or numbers were exposed
- Contact the organisation that issued the document (for example the passport office or the licensing authority) and ask what to do.
- Contact your national identity theft or cyber support service for help with identity theft (for example IDCARE in Australia and New Zealand).
- Watch for credit enquiries or accounts you did not open.
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.
