The Central Bank of Russia published its overview of customer-unauthorised transactions, reporting that banks’ anti-fraud systems blocked 134.2 million fraudulent transactions in 2025, up from 72.2 million in 2024, preventing an estimated RUB 13.9 trillion in potential client losses. Despite this, the amount stolen by fraudsters increased by 6.4% to RUB 29.3 billion. Reported fraudulent transactions rose by 31.2%, which the regulator linked mainly to a requirement for large banks to add a dedicated in-app button allowing customers to quickly report fraud, increasing notifications including of small-value thefts. The Bank of Russia also initiated the blocking of 69,100 fraudulent phone numbers and 38,400 fraudulent websites and social media pages, and noted that targeted cyber attacks against financial institutions remained high in 2025, with ransomware incidents increasing and infections most often occurring via contractors.
