ttmet.co.th Listed by incransom Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On December 26, 2025, the ransomware group incransom listed ttmet.co.th on its leak site. The listing states that internal files were exfiltrated during a ransomware attack, though the number of people affected and the precise contents of any exposed material remain undisclosed. The incident matters because ttmet.co.th handles machinery and parts for automotive manufacturing, a sector where operational records can include details about suppliers, clients, and employees. Any confirmed exposure of such files could affect individuals whose information appears in routine business documents.

Breaking down the breach

The only confirmed public detail is the December 26, 2025 listing by incransom. No information has been released about the date of the intrusion, the volume of data taken, or whether encryption occurred alongside the exfiltration. The scale of impact on individuals is listed as unknown.

Who is incransom?

Incransom is a ransomware operator that has appeared in public reporting since 2023. The group typically gains access through common entry points such as remote-desktop services or stolen credentials, then deploys encryption while copying selected files. It maintains a leak site where it posts names of organizations and sample data to pressure victims into paying ransoms. The listing of ttmet.co.th constitutes the group’s claim; independent confirmation of the data’s authenticity or volume has not been published.

ttmet.co.th and its sector

ttmet.co.th is a Thai company with approximately 150 employees and reported revenue of $30.4 million. It imports and exports machinery and spare parts used in automotive production and quality control, serving both domestic and international customers through wholesale, retail, installation, inspection, and maintenance services. Organizations in this part of the automotive supply chain routinely maintain records on equipment specifications, client contracts, shipping details, and staff administration.

The information in question

The listing refers only to “internal files exfiltrated in ransomware attack.” No inventory of file types or data categories has been made public. Companies of this size and sector commonly store employee records, customer contact information, supplier agreements, and technical documentation. The exact contents of any files that may have been taken are unconfirmed.

What's at stake

Individuals named in internal documents could face risks of targeted phishing or account misuse if their contact details or identifiers appear in the material. For the company, exposure of operational files could complicate supplier relationships or reveal proprietary specifications. No evidence has been presented that the data has been further distributed beyond the group’s claim.
