Ukraine cyber hack alleged behind Su-57 crash near Moscow
A Russian fifth‑generation fighter, a Su‑57, crashed near Moscow in July 2026. Russian state media initially described the loss as a technical malfunction during a training flight, with the pilot safely ejecting.
Ukrainian open‑source intelligence group InformNapalm claims the crash resulted from a Ukrainian cyber‑intelligence operation that penetrated Russia’s integrated air‑defence network and hijacked the BARS Moscow anti‑drone system, causing it to fire on the Su‑57. The group says the SBU redirected a Russian surface‑to‑air missile to strike the aircraft, marking what could be the first known case of a combat jet destroyed by a cyber‑enabled friendly‑fire incident.
Commentary from British defence analyst Hamish de Bretton‑Gordon called the episode a potential “Waterloo” for President Vladimir Putin, noting the Su‑57’s high cost (about $45 million per unit) and the limited number of aircraft in the Russian fleet, making each loss strategically significant.
