Moscow subway app and website disrupted in possible retaliation for Ukraine railway hack

The Moscow subway’s website and mobile app experienced outages that displayed a message similar to the recent Ukrzaliznytsia compromise, suggesting a possible cyberattack; authorities have not officially confirmed an attack. The outage disrupted online top-ups and digital travel passes for passengers, and the report situates the incident within a broader pattern of transport-targeted operations by Ukrainian and Russian hacker groups.
