A major cyberattack on Aeroflot, Russia's flagship airline, caused widespread flight disruptions on Monday. Over 100 flights were canceled and many more delayed due to a system outage. Ukrainian group Silent Crow and Belarusian group Belarus Cyber-Partisans claimed responsibility, boasting of data breaches and significant damage. The Kremlin acknowledged the "alarming" attack, while the hackers asserted they accessed Aeroflot's network for a year, compromising sensitive information. This is one of the most impactful cyberattacks against Russia since the Ukraine war began.
