German Drone Manufacturer Quantum Systems Reports Cyberattack by Hostile Actors
German drone manufacturer Quantum Systems, based in Gilching, announced that it was subjected to an active cyberattack by 'hostile actors' at the end of October 2026. The company's IT and security teams, in collaboration with authorities, successfully contained the threat. Following the incident, Quantum Systems reported it to relevant authorities as per regulatory obligations. Crucially, the company stated that there is 'no risk in operating Quantum Systems’ unmanned systems for the end users and the operators.' This assurance led to the German military's drones, which had been grounded as a precaution, resuming flight operations by November 13, 2026, as reported by Reuters. The investigation into the cyberattack is ongoing, involving state authorities and internal and external cybersecurity experts. While the company confirmed the attack and its containment, it has not disclosed the identity of the attackers, specific products affected, data stolen, or the number of systems compromised.
