BERLIN, Nov 13 (Reuters) - ⁠German defence technology group Quantum Systems said drones ⁠in service with the German military were ‌flying again after they were grounded as a precaution following a cyberattack last month.

The Financial Times reported on Thursday that the ​Bundeswehr had grounded drones made by ⁠Quantum Systems after ⁠the attack.

"The fleet is operating normally around the globe — ⁠including Germany ‌and the Bundeswehr," a Quantum Systems spokesperson said in an emailed statement. "The Bundeswehr ⁠was the only customer to ground their systems ​as a ‌precaution."

The Financial Times said the grounding had prevented ⁠Quantum Systems ​from taking part in a recent exercise with the military.

There was no immediate comment from the German military.

Quantum ⁠said "an active cyberattack by hostile ​actors" was detected in October but was contained by its IT and cybersecurity teams "in close and transparent collaboration ⁠with the authorities".

"Through the quick measures taken and the characteristics of the incident, there is no risk in operating Quantum Systems' unmanned systems for the end ​users and the operators," it ⁠said.

It was not immediately clear whether other companies may ​have been affected by the ‌attack.

Quantum Systems signed a deal ​last month to supply Ukraine with jet interceptors.
