The Netherlands Organization for Scientific Research (NWO) has been hacked by hacker group DoppelPaymer.

He gained access to the NWO network on 8 February and on Wednesday "started leaking internal NWO documents from recent years on the dark web", reports the organization, which is under the Ministry of Education, Culture and Science. falls Wednesday.

The leakage of documents has started, according to the science funder, because "on grounds of principle" the demands of criminals are not addressed.

"Although NWO deeply regrets that data of its own employees is now being made public unauthorized, this does not change this choice," said the organization, which expects to be able to restore the network in a few weeks.

"This will mean that some more stolen files may soon be made public again."

The requirements are not reported by the NWO.

De Volkskrant

, which was the first to report about the leaked documents, writes that the criminals would demand millions of euros in ransom.

DoppelPaymer uses ransomware (ransomware), which can lock files until users pay a ransom, for example.

Subsidy scheme temporarily suspended

The NWO announced earlier this month that it had been hacked.

Due to the hack, the processing of applications for research grants has been halted.

The NWO was founded to stimulate Dutch scientists.

The organization allocates nearly 1 billion euros in funding for researchers every year.

The organization awards the Spinoza Prize and the Stevin Prize every year.
