Hackers breached the IT systems of **Eurofins Clinical Diagnostics NMDL**, a laboratory responsible for cervical cancer screening in the Netherlands under the **Dutch Population Survey (BDO)**. Between **3–6 July 2025**, cybercriminals stole **sensitive personal health data** of **485,000+ women**, including **names, addresses, dates of birth, citizen service numbers, test results, and healthcare provider details**. The breach forced BDO to **temporarily suspend services** from the compromised lab and switch to an alternative provider. An **independent investigation** was launched by BDO and the **Dutch Ministry of Health, Welfare and Sport** to assess security failures. The incident highlights systemic vulnerabilities in **third-party healthcare providers**, where attackers exploit weak links in the supply chain. The breach follows a broader trend of escalating cyberattacks on healthcare, with prior cases (e.g., **2024 Synnovis ransomware attack on NHS**) causing **patient harm, delays in critical treatments, and even fatalities**. The stolen data—highly sensitive and irrecoverable—poses **long-term risks of identity theft, fraud, and blackmail**, deepening public distrust in medical data security.
