leaksear.ch has indexed an n-d-f.com leak containing 52,322 records with contact, identity, and account fields, including passwords, with a listed breach date of May 28, 2020 (leaksear.ch metadata). Public sources tie n-d-f.com to Japanese pet and animal-health content connected to Merial Japan, Boehringer Ingelheim Animal Health Japan, and Nippon Zenyaku Kogyo, but the dataset is identified in the index only by the n-d-f.com source name (prtimes.jp, www.zenoaq.com).
What happened
Public reporting reviewed for this article did not confirm how the n-d-f.com data was exposed. The available incident facts are limited to the dataset name, breach date, record count, indexed fields, and date indexed by leaksear.ch, June 29, 2026 (leaksear.ch metadata).
The domain appears in public sources as a destination for pet and veterinary product content. Merial Japan's 2017 PR Times release listed n-d-f.com pages for the Save Pet Project campaign, ZENOAQ product pages link to n-d-f.com animal-health product paths, and a 2019 Benesse dog-owner ranking listed n-d-f.com/nexgard for NexGard by Boehringer Ingelheim Animal Health Japan (prtimes.jp, www.zenoaq.com, www.zenoaq.com, dog.benesse.ne.jp).
Because the verified public sources do not identify a threat actor, ransomware group, storage error, scraping event, or third-party compromise, this report should not be read as attribution of the leak to any specific cause.
What data was exposed
The leaksear.ch index lists the following searchable fields in the dataset: address, country, date of birth, email address, name, password, phone number, and username (leaksear.ch metadata). The records also include an additional structured JSON field, but the metadata does not define the contents of that field (leaksear.ch metadata).
No raw records, passwords, or sample values are included here.
Why this matters
The combination of emails, usernames, and passwords creates credential-stuffing risk where people reused passwords on other services (leaksear.ch metadata). Names, phone numbers, addresses, countries, and dates of birth can also support targeted phishing, account recovery abuse, and identity-verification fraud. Security teams should prioritize password reset guidance, monitoring for reused credentials, and phishing lures referencing pet-health or veterinary content. If you may have used n-d-f.com or related pet-health pages, use the leaksear.ch lookup for this leak to check whether your data is present.
