In October 2024, the Dutch police blamed a state actor for the recent data breach that exposed officers’ contact details, the justice minister told lawmakers. The incident took place on September 26, 2024, and the police have reported the security breach to the Data Protection Authority.

Threat actors broke into a police system and gained access to work-related contact details of multiple officers. The attackers had access to names, emails, phone numbers, and some private information belonging to police officers.

Dutch intelligence agencies believe it is highly likely that a state actor was behind the data breach.
