Ukrainian hackers breached Gaskar Group, a major Russian military drone manufacturer, on July 15, 2025, destroying over 47 terabytes of technical data and crippling the company’s operations[1][2].

The cyberattack was carried out by Ukraine’s military intelligence (HUR) working with volunteer groups “BO Team” and the “Ukrainian Cyber Alliance”[2:1]. The hackers destroyed all data on the company’s servers, including 10 terabytes of backup files, and disabled the company’s internet services, production software, and accounting systems[2:2].

The stolen data included confidential employee records and complete technical documentation on drone production, which was transferred to Ukraine’s Defense Forces[2:3]. Documents revealed close cooperation between Gaskar Group and China in drone manufacturing[2:4].

This attack continues Ukraine’s pattern of targeting Russian military infrastructure through cyberwarfare. In August 2024, Ukrainian hackers conducted a mass cyberattack that affected 33 servers and 283 computers at Russian industrial facilities[3]. In April 2024, they destroyed a data center used by over 10,000 Russian military-related companies[4].
