Neogen data breach: 435K accounts exposed
Severity: medium · Patch status: no-fix-needed · Since 2026-10-09
In August 2026, the food and animal safety organisation Neogen was the target of a ShinyHunters "pay or leak" extortion attempt. The group later published data it claimed had been obtained from Neogen. The data consisted largely of corporate contact records and included 436k unique email addresses from mailing lists, employee records and other contacts. Exposed data: email addresses, employers, job titles, names, phone numbers, physical addresses, salutations. The breach dates from Aug 29, 2026; Have I Been Pwned loaded it on Oct 9, 2026.
What to do
- If you had a Neogen account, change its password and the password of any other account that reused it.
- Turn on multi-factor authentication wherever it is offered.
- Check whether your addresses are in this breach at https://haveibeenpwned.com.
- Expect targeted phishing that quotes the leaked details; verify any unexpected contact out of band.
