The leak post

captured from the group's site

DWI-Bausysteme für Metalldächer & Fassaden GmbH is a German construction-related company based in Kreuztal, North Rhine-Westphalia.
The company specializes in building systems for metal roofs and facades, serving customers in the construction and building sectors. Its activities are associated with metal construction, roofing and facade solutions, as well as the supply of related building products. The company operates in a specialized market where durable materials, weather resistance, technical compatibility and professional installation are important considerations. Its location in the Siegen-Wittgenstein region places it within an established industrial and construction economy in western Germany. Available third-party business listings identify it as a small enterprise, although detailed information about its workforce, customer portfolio and project volume is limited. The company’s financial information is not comprehensively available in public sources, so its annual turnover should be treated as an estimate rather than a verified financial figure.

Disclosure context

About safepay

The Safepay ransomware group is a newly emerged threat actor first observed in November 2024, demonstrating rapid operational scale with 444 documented victims in a short timeframe, indicating financially motivated cybercriminal activity. Due to the group's recent emergence, publicly documented information about their country of origin, affiliations, and operational model remains limited among established threat intelligence sources. Given the recency of their appearance and lack of detailed technical analysis from major security firms, their specific attack methodologies, initial access vectors, and encryption techniques have not been comprehensively documented in public threat intelligence reporting. The group has demonstrated a broad targeting approach across multiple sectors including manufacturing, technology, education, and healthcare, with primary focus on victims in the United States, Germany, Canada, the United Kingdom, and Australia, though no specific high-profile campaigns or notable incidents have been publicly attributed to them by major security vendors or law enforcement agencies. As of the latest available intelligence, Safepay appears to remain active, though comprehensive threat profiling is limited due to the group's recent emergence and the current lack of detailed technical analysis from established cybersecurity research organizations. The group has been linked to 900 public disclosures across our corpus. First observed on a leak site on November 19, 2024; most recent post October 10, 2026. The operation is currently active.

If your organisation is affected

A listing by safepay means dwi-bau.de appeared on a ransomware extortion site and data attributed to it has been published. If this is your organisation, or a supplier you depend on, the priority is to confirm the intrusion and contain it before the window to act closes.

Engage your incident-response team and preserve forensic evidence before remediating — do not wipe affected systems first.
Force a password reset and revoke active sessions for exposed accounts; rotate any credentials, API keys or certificates that may have been in the stolen data.
Assess regulatory notification duties (GDPR, NIS2, sector regulators) — many carry a 72-hour reporting clock from awareness.
Report the incident to your national CERT, CERT-Bund (Germany), as required for your jurisdiction.
Monitor for the data appearing on safepay's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.
