Threat-actor claim — not a regulatory filing

This row is a claim by the ransomware group INC Ransom on its public extortion blog. It has not been validated by the victim or any regulator. Treat attribution and counts as the threat actor's assertion until a regulatory filing or victim disclosure corroborates them.

Post text · scraped from the leak site

Berge-Bau is a German family-run construction firm operating since 1875, specializing in structural engineering, civil engineering, pipeline construction, and turnkey projects. Celebrating its 150th anniversary, the company serves industrial and residential clients from its Erndtebrück headquarters and a branch in Zeitz. ----------------- Unfortunately, this company’s management values its own bottom line more than the safety of its employees and partners. In three days, hundreds of pieces of personal data, as well as contracts containing non-disclosure clauses, will be made public. We are giving Berge-Bau one last chance to resolve this situation amicably.
