Details: Quantum Systems, a drone manufacturer that has risen to prominence during the war in Ukraine, has confirmed that it has been the victim of a cyberattack. The Bavarian defence start-up said a "cybersecurity incident" had been detected in late October 2026.

According to the Financial Times, the German armed forces have taken the company's drones out of service in response. The newspaper reported that the move was a precautionary measure following the incident at Quantum Systems. Germany's Defence Ministry declined to comment on reports in the media when contacted in Berlin.

In a statement, the drone manufacturer, based in Gilching near Munich, also explained that an immediate internal investigation had uncovered an active cyberattack by hostile actors. The threat was contained by the company's IT and security teams in close and transparent cooperation with the authorities.

Thanks to the measures taken and the nature of the incident, the operation of the systems poses no risk to end users or operators. The incident has been reported to the relevant authorities, and an investigation is ongoing.

Quantum Systems manufactures drones for both military and civilian use. Until now, its main focus has been on reconnaissance and surveillance drones. The company is also developing surface and underwater drones. Among its latest products is the Reliant unmanned reconnaissance system, which can continuously monitor large areas for more than ten hours, takes off vertically and features integrated artificial intelligence.

Another key area of development is Mosaic software for managing unmanned systems. Quantum drones are used by the Armed Forces of Ukraine in the country's defensive war against Russia.

Background:

In October, it emerged that Quantum Systems was planning to provide Ukraine with tens of thousands of Spys interceptor drones designed specifically to counter Russia's new Geran-4 and Geran-5 jet-powered UAVs.
In late 2025, it emerged that Ukrainian drone manufacturer Frontline Robotics and German defence company Quantum Systems would launch production of attack drones in Germany for Ukraine.
