About This Record
What information was compromised in the NDF Japan incident?
The leaked MariaDB database dump contains over 1.1 million reminder notification logs and more than 110,000 veterinary clinic master entries. Verified data classes include:
- Personal & Contact Credentials: Pet owner full names, residential postal addresses, telephone/mobile numbers, and primary email addresses.
- Veterinary & Clinic Identifiers: Associated veterinary clinic names, veterinary staff IDs, and clinic registration records.
- Pet Healthcare Data: Pet names, animal breeds, species categorizations, and medication reminder schedules.
How many accounts were affected?
Standardized RFC 5322 ASCII canonical verification confirmed 53,742 unique valid email addresses across 1.1 million healthcare notification rows.
Security advisory & personal identity protection
The exposure of physical addresses, telephone numbers, and pet medical histories heightens risks of targeted social engineering and veterinary billing scams. Impacted individuals should:
- Remain watchful regarding unsolicited communications claiming to represent animal clinics or medication providers.
- Verify any billing or subscription requests directly with their registered veterinary clinic.
