Description
German defense manufacturer Quantum Systems confirmed on November 12 that its systems had been targeted in a cyberattack during late October. The company, which produces drones for land, air, and maritime operations including interceptor models, stated that its security team had contained the attack and that its drones remained safe to use. Quantum Systems attributed the intrusion to hostile actors but did not disclose their identity or indicate whether Russia was involved. In an official statement, the company said that organizations at the forefront of supporting Ukraine are being targeted because their work is critically relevant to customers' security. The firm said it was investigating the incident alongside German authorities and cybersecurity experts.
The attack occurred against a backdrop of rising cyber activity against the European defense industry, a trend that has accelerated since Russia's full-scale invasion of Ukraine and has particularly affected companies supplying weapons and military equipment to Kyiv. Quantum Systems is a major supplier of reconnaissance drones to Ukraine and has expanded its production within the country since the invasion began. The company opened a drone factory in Ukraine in April 2024. In December 2025, Quantum Systems announced a partnership with Ukrainian drone maker Frontline Robotics to produce Ukrainian-designed drones in Germany. Germany also announced plans in October 2026 to fund the production of tens of thousands of interceptor drones by Quantum Systems in Ukraine.
