Nedved Architekti Listed by spacebears Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

Ransomware groups continue to target professional services firms by combining data theft with public pressure, listing organisations on leak sites to force negotiations. In this environment, even smaller specialist practices can find themselves named alongside much larger victims, often with limited public detail about what actually occurred.

On 3 May 2025, the Czech architecture studio Nedved Architekti was listed by the ransomware group spacebears. The group claims that internal files were exfiltrated in a ransomware attack. The number of people affected remains unknown, and many operational details have not been disclosed. For clients, partners and staff of a design practice that handles project files and personal information, the listing raises clear questions about what may have been taken and what risks follow.

Breaking down the breach

Public reporting states that Nedved Architekti was listed by spacebears on 3 May 2025. The available information describes the incident as a ransomware attack in which internal files were allegedly exfiltrated. No confirmed figure has been given for the volume of data, the number of individuals affected, or the precise date the intrusion began. The method of initial access, the duration of any dwell time inside the network, and whether encryption was also deployed have not been publicly detailed. The listing itself is a claim by the threat actor; independent confirmation of the full scope has not been provided in the available record.

The reported summary associated with the listing references projects in PDF and DWG formats, personal information and other documents, alongside a description of the studio’s work and its public website. Beyond the statement that internal files were taken, further technical specifics remain undisclosed.

Who is spacebears?

Spacebears is a ransomware operation that follows the now-common double-extortion model: data is stolen before or during encryption, and the victim is then threatened with public release if a ransom is not paid. Like other groups in this category, spacebears maintains a leak site where it posts the names of organisations it claims to have compromised, sometimes accompanied by sample files or descriptions of the stolen material. The group’s public activity has focused on pressure through disclosure rather than purely technical disruption.

In this case, spacebears has listed Nedved Architekti and asserted that internal files were exfiltrated. No additional statements from the group about this specific victim—such as ransom demands, deadlines or sample data—are included in the available facts. The listing should therefore be treated as an unverified claim until corroborated by the organisation or independent investigators.

About Nedved Architekti

Nedved Architekti is an architecture studio whose stated focus is the search for new spatial solutions for interiors and exteriors in both public and private settings. The practice emphasises the harmonious connection of detail and whole through materials, light and colour, treating design and architecture as carriers of a story that links the creator’s vision with client needs. Its public materials describe work on projects that generate drawings, specifications and related documentation.

Architecture firms of this type routinely hold project files (including CAD drawings such as DWG and presentation PDFs), client correspondence, contracts, and personal data of staff, clients and collaborators. A breach at such a practice is consequential because the material is often commercially sensitive, long-lived, and tied to real people and real buildings. Even without confirmed scale, the combination of design intellectual property and personal information creates lasting exposure risks.

What was likely exposed

The facts state that internal files were exfiltrated in a ransomware attack. The associated summary references projects in PDF and DWG formats, personal information and other documents. Exact contents, file counts and whether any particular category was confirmed as taken have not been independently verified. Organisations of this kind typically store architectural drawings, project documentation, client contact details, contracts, invoices and employee records. Because the precise inventory remains unconfirmed, it is not possible to state with certainty which of these categories were present in the stolen data.

The real-world impact

For individuals whose details may have been among the internal files, the practical risks include phishing or social-engineering attempts that reference genuine projects or relationships, potential misuse of contact information, and longer-term identity or privacy concerns if personal data was included. For the studio itself, exposure of project files can affect competitive position, client trust and contractual obligations, particularly where drawings or specifications contain proprietary design solutions. Because the number of people affected is unknown and the full data set has not been publicly itemised, the extent of these risks cannot yet be quantified. The organisation faces the dual task of containing any ongoing access and communicating clearly with those who may be impacted.

Were you affected?

If you have worked with Nedved Architekti as a client, collaborator or employee, treat any unexpected messages that reference specific projects or personal details with caution. Change passwords on accounts that may have been reused, enable multi-factor authentication where available, and monitor financial and email accounts for unusual activity. Consider placing a fraud alert with credit agencies if you believe personal identifiers were involved. Readers can also run a free exposure scan of their email address to check whether that address has already appeared in known breach data sets; such a check is a practical first step while waiting for any official notification from the organisation.
