Pet microchip scams and data leaks in the UK

An investigation into UK pet microchip databases highlights leaky data practices and inconsistencies: sequential chip IDs enable enumeration that exposes owner contact details via public lookups; elevated-access vet/warden/police portals often use shared credentials without MFA or adequate rate limiting; and a suspected 2021 Petlog data incident may have contributed to third-party PetChip.info datasets used for renewal solicitations. The authors call for stronger government standards, better access controls, MFA, and consistent disclosure policies across approved registries.
