Quantum Systems reports cyberattack as Bundeswehr pulls its drones, report says

Quantum Systems, the Bavarian drone manufacturer whose products are used by Ukraine's armed forces, has reported a cyberattack, saying it detected a cybersecurity incident at the end of October 2026.

The company, based in Gilching near Munich, said an immediate internal investigation uncovered an active cyberattack by hostile actors. It said the threat had been contained by its IT and security teams in close and transparent cooperation with the authorities, and that the incident had been reported and was under investigation. The company said there was no risk to end users or operators running its systems.

A press report said the Bundeswehr had withdrawn the company's drones from service as a precaution after the incident. The defence ministry declined to comment on the media report when asked in Berlin.

Quantum Systems makes drones for military and civil use, with a focus so far on reconnaissance and surveillance. It is developing over- and underwater drones, and its newer products include the Reliant unmanned reconnaissance system, which can monitor large areas continuously for more than ten hours, takes off vertically and carries onboard AI. The company is also developing Mosaic, control software for unmanned systems.

Its drones are used by Ukrainian forces in the war against Russia.
