Geometrics Listed by sinobi Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Geometrics was listed by the sinobi ransomware group on 22 December 2025, with internal files reported as exfiltrated in the incident. An undisclosed number of people may have been affected; individuals should check any notifications from Geometrics and change passwords or enable additional security measures if their information may be involved.
What happened
Public reporting on the incident is confined to the group's listing of Geometrics. The entry indicates that files were removed from the company's systems in connection with ransomware activity. No confirmed information has been released about the date of the intrusion, the volume of data involved, or the method used to gain access. Geometrics has not issued a public statement confirming or disputing the claims in the listing.
The group behind it: sinobi
Sinobi is a ransomware operator that maintains a leak site where it publishes names of organizations it claims to have targeted. The group follows the common pattern of encrypting systems and threatening to release stolen data if a ransom demand is not met. Its listings typically include a brief description of the victim and an assertion that files have been taken. Attribution in these cases rests on the group's own statements rather than independent verification of the underlying events.
Who is Geometrics?
Geometrics is a division of OYO Corporation headquartered in San Jose, California. Founded in 1969, the company designs and manufactures geophysical instruments and software used for land, marine, and airborne surveys. Its products cover seismic, magnetic, and electromagnetic sensing technologies and are employed in resource exploration, environmental monitoring, and infrastructure assessment. As a specialist hardware and software provider, the firm holds technical specifications, client project data, and operational records that are not ordinarily public.
The information in question
The listing describes the exposure of internal files. No inventory of specific file types or data categories has been published. Organizations in the geophysical instrumentation sector routinely maintain engineering drawings, sensor calibration records, customer contracts, and proprietary software components. Whether any of these categories were among the files referenced in the listing has not been confirmed.
What's at stake
Exposure of internal technical and operational files can reveal details about product designs and client engagements that competitors or other parties might use. For individuals whose information appears in project or contractual records, the primary concern is the potential for targeted follow-on activity such as phishing or account compromise. The organization faces the separate task of assessing whether any systems remain under unauthorized control and of notifying affected parties if required by applicable regulations.
What to do if you're exposed
Individuals who believe their information may have been involved should monitor their email accounts and financial statements for unusual activity. Enabling multi-factor authentication on any accounts that reuse passwords from the affected organization is a prudent first step. Readers can also run a free exposure scan of their email address against known breach data sets to determine whether their information has appeared in previously published incidents.

Publicly posted by sinobi — unverified claim, pending independent verification
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.
