Nijhuis Bouw B.V.

Profile narrative

Nijhuis Bouw B.V. is a Dutch construction company headquartered in the Netherlands that specialises in housing renovation projects. Its core activities involve planning, executing, and managing refurbishment work for residential properties, serving clients within the Dutch housing sector. The firm operates primarily within the national market, focusing on delivering renovation services that address the needs of residents and housing partners. A distinguishing attribute of the organisation is its direct interaction with residents whose personal data may be processed during renovation initiatives, as evidenced by the handling of names, addresses and phone numbers in its projects. The company also demonstrates a capacity to engage external specialist negotiators and cybersecurity experts when responding to security incidents, reflecting a procedural approach to crisis management.

In February 2025, Nijhuis Bouw B.V. experienced a ransomware cyberattack that potentially exposed personal information of residents linked to its housing renovation work. Although the company, working with specialist negotiators, secured the attacker’s pledge to delete the data and refrain from publishing it, it could not completely exclude the possibility that the information had been exfiltrated. Affected computer systems were restored quickly and securely with the assistance of cybersecurity specialists, allowing operations to resume. The housing partner associated with the projects notified the impacted residents, advising them to remain alert to possible phone and email fraud attempts stemming from the breach. This incident highlights the organisation’s reliance on external expertise for both negotiation and technical recovery during cybersecurity events. No further details regarding ownership, parent or subsidiary relationships, or quantitative scale are provided in the available sources.
