Hackers penetrated the internal infrastructure of German drone manufacturer Quantum Systems and introduced malware disguised as an official software update, the Financial Times and Der Spiegel report. The fake patch compromised the Bundeswehr's servers, causing the German armed forces to temporarily suspend the flights of the company's entire fleet of UAVs. Quantum Systems confirmed the fact of the cyber attack at the end of October, and assured that there are currently no risks in operating the devices.
