tambasa.com Listed by incransom Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Tambasa.com was listed by the Incransom ransomware group on July 01, 2026, with internal files reported as exfiltrated. Anyone who may have interacted with the site should check for notices from Tambasa and take steps to protect their accounts and data.
The listing of tambasa.com by the incransom ransomware group indicates that internal files from the Brazilian wholesale distributor were taken during a ransomware incident. Because the number of individuals affected remains unknown and the precise contents of the files have not been detailed publicly, the practical consequences for customers, suppliers, and employees depend on what the stolen material actually contains.
What happened
On 2 July 2026 the incransom group listed tambasa.com on its leak site. The only confirmed detail is that internal files were allegedly exfiltrated during a ransomware attack. No information has been released about the date of the intrusion, the volume of data taken, or whether any of the material has been published.
Inside incransom
Incransom is a ransomware operation that typically gains access to corporate networks, deploys encryption, and removes copies of selected files before demanding payment. The group maintains a public leak site where it lists organizations it claims to have compromised. In this case the group claims tambasa.com as a victim; independent confirmation of the claim or of any subsequent data release has not been reported.
Who is tambasa.com?
Tambasa Atacadistas, operating through tambasa.com, is a large B2B wholesale distributor founded in 1949. It supplies retail stores, supermarkets, and construction businesses across Brazil. Organizations of this type routinely hold records on suppliers, pricing agreements, delivery schedules, and customer accounts.
What data was at risk
The only data category named in connection with the incident is “internal files exfiltrated in ransomware attack.” The exact nature of those files has not been disclosed. Companies in the wholesale distribution sector commonly maintain commercial contracts, inventory records, financial documents, and contact information for business partners; whether any of these categories are present in the exfiltrated material remains unconfirmed.
The real-world impact
Exposure of internal commercial files can create competitive or operational risks for the company and its trading partners. For individuals whose information appears in those files, the main concerns are potential misuse of contact details or business-related personal data. No evidence of large-scale publication or direct consumer harm has been reported to date.
