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.
