Yew Tree Dairy Listed by interlock Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Yew Tree Dairy was listed by the interlock ransomware group on 16 February 2026 after internal files were exfiltrated. Anyone connected to the dairy should check for notifications and take steps to protect their information.
What happened
The incident was first noted publicly when Interlock added Yew Tree Dairy to its leak-site listing. The group claims internal files were exfiltrated. No further details on the timing of the intrusion, the method of entry, the volume of data, or any ransom demand have been released by the company or confirmed by investigators.
Inside interlock
Interlock is a ransomware group that publishes victim names on a dedicated leak site when negotiations fail or to increase pressure. Like other groups of its kind, it typically combines encryption of systems with the threat of data publication. Public reporting on the group’s prior activity shows it has targeted organisations across multiple sectors rather than specialising in one industry.
Yew Tree Dairy and its sector
Yew Tree Dairy is a family-owned business established in 1904 that produces and supplies fresh milk, cream and milk powder, mainly to wholesalers and retailers. Food-production and distribution companies routinely maintain records on suppliers, delivery schedules, customer accounts and staff. A compromise in this sector can affect both commercial operations and any personal data held in the same systems.
What data was at risk
The only information released is that internal files were allegedly exfiltrated. The precise categories of data contained in those files have not been disclosed. Organisations of this type commonly store contact details for business partners, order histories, financial records and employee information, but it is not confirmed whether any of these were present or taken.
The real-world impact
Until the contents of the files are known, the risks to individuals remain general. Exposed business records can lead to follow-on fraud attempts or misuse of contact information. For the company, the incident adds operational disruption from any recovery work and potential loss of trust among customers and suppliers.

Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
