Deibel Laboratories Listed by anubis Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

Ransomware groups continue to target organizations across critical supply chains, including those responsible for food safety testing. On December 19, 2025, Deibel Laboratories, a U.S. laboratory specializing in food safety and quality testing, was listed by the group anubis on its leak site. Public information about the incident remains limited to the listing itself and a brief description of internal files being exfiltrated during a ransomware attack. The number of individuals affected has not been disclosed.

Such listings have become a standard element of ransomware operations, where groups publish victim names to increase pressure for payment. The available facts do not include confirmation of the data's contents, the attack timeline, or any ransom demand. This leaves the precise scope and impact of the incident unverified beyond the group's claim.

Inside the incident

The incident involves a ransomware attack on Deibel Laboratories in which internal files were reportedly exfiltrated. The breach was publicly noted through a listing by the anubis group on December 19, 2025. No further details on the date of the intrusion, the volume of data taken, or the methods used have been released. The number of people whose information may have been involved remains unknown.

The group behind it: anubis

Anubis is a ransomware operation that maintains a leak site to publish names of organizations it claims to have compromised. Groups of this type typically gain initial access through common vectors such as compromised remote access services or phishing, then move laterally to locate and encrypt data while often copying files beforehand. The listing of Deibel Laboratories constitutes the group's claim of involvement; independent confirmation of the underlying events has not been made public.

Deibel Laboratories and its sector

Deibel Laboratories operates as a food safety and quality testing facility in the United States. Laboratories in this sector perform analytical work for food producers, processors, and distributors, generating records that can include test results, client correspondence, and internal operational documents. A compromise at such a facility can affect both the laboratory's own records and information belonging to client companies that rely on its services.

What data was at risk

The only data category named in connection with the incident is internal files exfiltrated during the ransomware attack. The specific nature or contents of those files have not been disclosed. Organizations of this type routinely hold client-submitted samples and associated test data, regulatory documentation, and business records; however, whether any of these categories were among the files taken remains unconfirmed.

Why it matters

Exposure of internal files from a testing laboratory can create downstream effects for client businesses that depend on the laboratory's results for compliance and product safety decisions. For any individuals whose personal information appears in those files, the primary risks involve potential misuse of contact details or account credentials if such data were present. The organization itself faces operational disruption and the cost of investigation and recovery, though the scale of these consequences is not yet known.

What to do if you're exposed

Individuals concerned about possible exposure should monitor their financial and email accounts for unusual activity and enable multi-factor authentication where available. Changing passwords for any services that may have been referenced in laboratory records is a prudent step. Readers can also run a free exposure scan of their email address against known breach data to determine whether their information has appeared in previously published datasets.
