GermanyA malicious software update reportedly reached military servers.
Quantum Systems also supplies Ukraine, and Germany is funding tens of thousands of its interceptor drones.
Unnamed sources say the malware sat in an update to QBase, the ground-control software, and did not directly infect the drones.
The company says it contained the threat and the Bundeswehr was the only customer to ground its systems.
Quantum Systems disclosed few details of the intrusion, and the defence ministry declined to comment.
