Drivers on motorways and provincial roads may escape fines for speeding because of last month’s hack of the public prosecution office.

According to local paper Leeuwarder Courant, “dozens” of speed cameras along A and N roads were taken offline as a result of the cyberattack in June.

A spokesman for the public prosecution service (Openbare Ministerie) confirmed that all systems linked to the OM had to be disconnected, including several fixed and movable speed cameras, but did not specify locations. The cameras themselves were not hacked, he said.

The OM is still processing the aftermath of the attack, which is thought to have been the work of Russian hackers. Affected systems contain sensitive information on ongoing police investigations and court cases, as well as personal data on staff. The justice department has not yet said what, if any, information was accessed.

It is not clear when the cameras will be operational again. Systems will be reconnected step by step, the spokesman told broadcaster NOS.
