The drone manufacturer Quantum Systems, which became known through the Ukraine war, says it has fallen victim to a cyber attack. The Bavaria-based defense start-up announced that a “cybersecurity incident” was detected at the end of October 2026.

According to a report in the Financial Times, the Bundeswehr is said to have taken the company's drones out of circulation. The paper writes that she took this measure as a precautionary measure after Quantum Systems was affected by the incident. When asked in Berlin, the Ministry of Defense did not comment on the media report.

The announcement from the drone manufacturer from Gilching near Munich further states that an immediate internal investigation revealed an active cyber attack by hostile actors. The threat was “contained” by its IT and security teams in close and transparent cooperation with the authorities.

Due to the measures taken and the nature of the incident, there is no risk for end users and operators when operating the systems. The incident was reported to the relevant authorities and is currently being investigated.

Quantum drones are used by Ukrainian armed forces

Quantum Systems produces drones for both military and civilian use. So far the focus has been on reconnaissance and surveillance drones. Surface and underwater drones are also in development.

Newer products include the Reliant unmanned reconnaissance system, which can continuously monitor large spaces for more than ten hours, launches vertically and is equipped with on-board AI.

Another focus of development is the control software for unmanned systems called “Mosaic”. Quantum drones are used by the Ukrainian armed forces in the defensive war against Russia.
