BERGE-BAU GmbH & Co. KG
About the organisation
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.
What the listing means
BERGE-BAU GmbH & Co. KG appeared on the incransom leak site on 03 April 2026. Groups publish a victim once negotiations stall or as pressure during them, so a listing usually means data was already exfiltrated. This group has published 33 claims in the last 30 days and remains active.
Recommended actions
- Treat any unsolicited message referencing BERGE-BAU GmbH & Co. KG as suspicious — leaked data gets weaponised for phishing within days.
- If you hold an account on berge-bau.de, change that password now, update it anywhere you reused it, and enable two-factor authentication.
- Other Construction organisations should review this group's known TTPs and validate detection coverage against them.
- Watch for follow-on extortion: stolen data is often re-leaked or resold after the initial listing.
- A leak-site listing is a claim made by the attacker, not a confirmed breach — check the organisation's own disclosures before acting on it.
