• Country: United States
• Sector: Professional Services
• Announcement date: December 12, 2025

The ransomware group known as minteye has listed the professional services firm David M. Schwarz Architects on its leak site. The announcement, which appeared on December 12, 2025, claims that the group has successfully compromised the organization's systems and is in possession of a significant volume of data.

The claimed attack and event details

According to the announcement published by the minteye group, the breach occurred prior to the public listing. The group alleges that they obtained access to the systems of David M. Schwarz Architects on December 7, 2025. This timeline suggests that the attackers may have maintained presence within the network for several days before making their claims public on the leak site.

Ransomware groups often utilize leak sites as a tool for double extortion. In these scenarios, attackers do not merely encrypt an organization's files to disrupt operations; they also steal sensitive data to use as leverage. By threatening to publish stolen information, the threat actors attempt to pressure the victim into paying a ransom to prevent the public exposure of proprietary or confidential information.

Data involved in the claim

The minteye group has made specific claims regarding the volume of information they have allegedly exfiltrated from the target. The group asserts that they are holding a total of 1.9 TB of data. While the volume of the data is specified, the group has not provided any specific details or screenshots regarding the actual content of the allegedly leaked data.

The listing names no specific data types or categories of files that have been compromised.

Potential impact and organizational risks

This claim poses several significant risks to the institution's operational continuity and its commercial reputation. The potential exposure of 1.9 TB of data could jeopardize the firm's intellectual property and the confidentiality of its clients. For an architecture firm involved in large-scale urban and commercial projects, the loss of sensitive design documents or client information can have long-term consequences.

Furthermore, as a United States-based institution, a potential data breach may lead to legal consequences under state laws and federal regulations. If the data is eventually published by the threat actors, it may result in identity theft or targeted phishing attacks directed against the firm's employees and clients.

In the professional services sector, organizations often face these types of threats. To mitigate such risks, companies typically focus on defensive measures such as implementing robust access controls, maintaining regular offline backups, and conducting continuous monitoring of their network environments. Public information regarding the specific activities and methods of the minteye group remains limited.
