Dutch data scandal: illegal trade of COVID-19 patient data

In recent months, a RTL Nieuws reporter Daniël Verlaan has discovered widespread trade in the personal data of Dutch COVID-19 test subjects. He found ads consisting of photos of computer screens listing data of Dutch citizens. Apparently, the data had been offered for sale on various instant messaging apps such as Telegram, Snapchat and Wickr. The prices ranged from €30 to €50 per person. The data included home addresses, email addresses, telephone numbers, dates of birth and BSN identifiers (Dutch social security number).

The personal data were registered in the two main IT systems of the Dutch Municipal Health Service (GGD) – CoronIT, containing details about citizens who took a COVID-19 test, and HPzone Light, a contact-tracing system, which contains the personal data of people infected with the coronavirus.

After becoming aware of the illegal trade, the GGD reported it to the Dutch Data Protection Authority and the police. The cybercrime team of the Midden-Nederland police immediately started an investigation. It showed that at least two GGD employees had maliciously stolen the data, as they had access to the official Dutch government COVID-19 systems and databases. Within 24 hours of the complaint, two men were arrested. Several days later, a third suspect was tracked down as well. The investigation continues, since the extent of the data theft is unclear and whether the suspects in fact managed to sell the data. Therefore, more arrests are certainly not excluded.

Chair of the Dutch Institute for Vulnerability Disclosure, Victor Gevers, told ZDNet in an interview:

Because people are working from home, they can easily take photos of their screens. This is one of the issues when your administrative staff is working from home.

Many people expressed their disapproval of the insufficient security measures concerning the COVID-19 systems. Since the databases include very sensitive data, the government has a duty to protect these properly in order to prevent criminal misuse. People must be able to rely on their personal data being treated confidentially.

In a press release, the Dutch police also raised awareness of the cybercrime risks, like scam or identity fraud. Moreover, they informed about the possibilities of protection against such crimes and the need to report them. This prevents victims and allows the police to immediately track down suspects and stop their criminal practices.
