Rodgau (dpa / lhe) – The city administration of Rodgau has become the victim of a hacker attack. The systems have not been running since Thursday morning, a city spokeswoman said on Friday. An attempt is now being made to restart the network piece by piece. How long this will take cannot yet be estimated. The authority had initially assumed a technical defect on Thursday. In the course of the day, the indications of a cyber attack increased. The city administration and the municipal utilities can only be reached by telephone via the central numbers.
