InformNapalm reports a HUMINT+CYBINT operation that led to Russian air defense shooting down their own Su-57 fighter in Moscow region. Analysts intercepted training streams from BARS Moscow air defense crews, identified system vulnerabilities and influenced the crew to target Russian aircraft instead of Ukrainian drones. Russia's Defense Ministry blamed a "technical malfunction" while Z-channels discuss sabotage. The BARS Moscow system was created to protect the capital region from Ukrainian long-range drones but ended up eliminating Russia's own fifth-generation fighter.
