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.

Axar.az reports, citing Reuters, that the Bundeswehr had grounded ​drones made by Quantum Systems after the ​attack, the FT said.

"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.
