An internal investigation found an active cyber attack carried out by hostile actors, the company said. Its IT and security teams, working with authorities, contained the threat.

Bundeswehr reportedly halts drone use

The Financial Times reported that the German armed forces, the Bundeswehr, had taken Quantum Systems drones out of service as a precautionary step after the company was affected (Quantum Systems drones grounded by German military after cyber attack – Financial Times).

Company says operators face no risk

Quantum Systems stated that, given the measures taken and the nature of the incident, end users and operators face no risk when running its systems.
