On January 20, 2026, the ransomware group Incransom added Sandberg to its public leak site and began publishing more than 100 GB of the company’s internal files. The independent consultancy, founded in 1860 and known for materials testing and inspection work in the construction sector, had its confidential documents, client data, NDAs, financial records, operational files, business agreements, and transaction databases exposed.

What Public Reporting Shows
Public reporting indicates that Incransom claims to have exfiltrated the data during a ransomware attack on Sandberg. The leak site lists categories including confidential documents, clients data, NDA agreements, financial data, operations information, corporate data, business agreements, development materials, and financial databases containing all transactions and client records. Available reporting describes the total volume released so far as 100 GB. No confirmed count of individuals whose personal information appears in the files has been published.
Why This Matters for You and Your Family
When a company like Sandberg suffers a breach, the information that surfaces can include names, addresses, contact details, and financial arrangements tied to clients, suppliers, or employees. If your family has ever worked with a construction firm, materials testing service, or consultant that uses Sandberg, your data may now sit in a publicly accessible ransomware repository. Once that material is downloaded and shared on underground forums, it can be combined with other leaks to build detailed profiles that put household finances, addresses, and daily routines at risk.
Credential leaks from corporate databases often cascade far beyond the original victim. A password or email address taken from a business agreement can be tested against personal accounts you use for banking, shopping, or your children’s online activities.
