Trine Access Technology Listed by sinobi Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Trine Access Technology was listed by the sinobi ransomware group on December 16, 2025, after internal files were exfiltrated in a ransomware attack. The number of people affected has not been disclosed; individuals should check whether their information was involved and take appropriate protective steps.
On December 16, 2025, the ransomware group sinobi listed Trine Access Technology on its leak site, claiming to have exfiltrated internal files during a ransomware operation. Public details remain limited: the number of individuals affected is unknown, the volume or specific contents of any data have not been confirmed, and no independent verification of the incident has been reported. The listing places the event within a broader pattern of ransomware activity targeting manufacturers and suppliers whose systems hold operational and customer-related records.
Breaking down the breach
The only confirmed public information is the December 16, 2025 listing itself. The group claims internal files were taken; no timeline for the intrusion, method of initial access, or encryption of systems has been disclosed. The scale of the operation, including whether data was published or offered for sale, is not publicly documented beyond the initial claim.
Inside sinobi
Sinobi is a ransomware operator that maintains a leak site to publicize claimed victims. Groups of this type typically gain access through phishing, exposed remote services, or compromised credentials, then exfiltrate data before deploying encryption. Their listings serve as pressure tactics in extortion attempts. The appearance of Trine Access Technology on the site constitutes the group’s assertion of responsibility; no additional statements or evidence from the actor specific to this target have been released.
Who is Trine Access Technology?
Trine Access Technology was established in 1999 and manufactures electric strikes and related access-control hardware. The company supplies components used in physical security systems across commercial and institutional settings. Organizations in this sector routinely maintain records on product designs, customer orders, supplier relationships, and internal operations. A compromise at such a firm can expose both business information and any personal data collected in the course of sales or support.
What data was at risk
The listing refers only to “internal files.” No inventory of file types, databases, or personal identifiers has been made public. Manufacturers of this kind commonly store customer contact details, order histories, technical specifications, and employee records. Because the precise contents remain undisclosed, it is not possible to state which categories of information, if any, were taken.
What's at stake
Exposed operational files could reveal details about security products or client installations that third parties might misuse. If personal information was among the files, affected individuals face the standard risks associated with leaked contact or account data, such as targeted phishing. For the company, the incident adds to the operational burden of investigating the intrusion and responding to any regulatory or contractual obligations that may arise.
If your data was in this claimed breach
Individuals who have done business with Trine Access Technology should monitor their email and financial accounts for unusual activity. Enabling multi-factor authentication on any accounts that may share reused passwords is a standard precaution. A free exposure scan of an email address against known breach data can indicate whether information has appeared in previously published datasets, though it cannot confirm presence in this specific incident.

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.
