Binance said it cooperates with law enforcement worldwide through structured processes that follow legal, privacy, sanctions and regulatory requirements, after Reuters detailed how Russian investigators used customer records from the exchange in a terrorism-financing case against Yuri Belenkiy. The report underscores that Binance's 2023 exit from Russia ended its commercial operations there but did not necessarily erase historical customer data held under compliance retention rules. Reuters said investigators obtained Belenkiy's records through requests answered from a Binance email address previously listed for Russian and Belarusian agencies. Belenkiy, a Russian IT specialist detained in September 2025, is accused of sending just over $700 to Ukrainian military fundraisers, which Moscow classifies as terrorism financing. Binance said it cooperates with lawful information requests globally, subject to applicable legal, privacy and regulatory requirements, and has maintained that position since earlier disputes over data-sharing allegations in Russia. The episode highlights how centralized exchanges can connect public blockchain activity to identified users through KYC records, even after leaving a market. It also raises fresh scrutiny over whether any disclosure to Russian authorities complied with European data-transfer rules, including GDPR guidance that foreign demands generally require an international legal basis such as a mutual legal assistance treaty.
