safepay ransomware group lists wolfusofsky.de on its leak site

• Ransomware group: safepay
• Country: Germany
• Announcement date: September 30, 2026

The German construction company wolfusofsky.de has been listed on the leak site of the safepay ransomware group. This listing, appearing on September 30, 2026, represents a process in which the group claims to have obtained the company's data.

The claim by safepay

On September 30, 2026, the safepay group officially listed wolfusofsky.de on its dedicated leak site. As part of this announcement, the group published a summary detailing the company's professional activities within the construction and infrastructure sectors. This public listing serves as the group's method of claiming responsibility for a purported breach of the organization's digital environment.

Ransomware leak sites are platforms used by cybercriminal groups to pressure victims into paying ransoms. These sites often host lists of companies that have refused to meet the attackers' demands. When a company is listed, it typically signals that the threat actors claim to have successfully exfiltrated sensitive information from the target's network.

Details regarding the alleged data exfiltration

Despite the listing on the safepay leak site, the announcement does not contain specific details regarding the nature of the data allegedly exfiltrated. There is no information provided concerning the specific types of files, the total volume of data, or the exact number of files involved in the incident.

The listing names no specific data types.

The mechanics of double extortion

The situation highlights the common tactic known as double extortion. In this scenario, ransomware actors do not merely encrypt a victim's systems to disrupt operations; they also steal sensitive data before the encryption occurs. The threat of leaking this stolen information on a public site provides the attackers with additional leverage, as the victim faces not only operational downtime but also the threat of public exposure and regulatory scrutiny.

Organization profile

Wolf & Sofsky is a construction company providing a broad range of construction and infrastructure services to public and private clients in the Rhineland-Palatinate and Saarland regions of Germany.

Potential implications and risks

Considering the double-extortion tactics employed by the safepay group, there is a possibility that sensitive information such as trade secrets and employee data may have been compromised. Because the company is based in Germany, a potential data breach could lead to legal and administrative sanctions under the EU General Data Protection Regulation (GDPR).

Furthermore, since the company provides services to both public and private sector clients, supply chain risks and third-party interactions may be heightened. The subsequent publication of data could result in reputational damage and an increase in targeted phishing attacks against the company's clients.

For organizations operating in the construction and infrastructure sectors, maintaining robust security postures is critical to mitigating these risks. Common defensive steps include implementing multi-factor authentication, maintaining regular offline backups, and conducting thorough third-party risk assessments to secure the supply chain. Public information regarding the safepay group remains limited.
