Binance Supplied Customer Data to Russian Authorities in Terrorism Financing Case

Cryptocurrency Exchange Complies With Russian Law Enforcement in Terrorism Financing Investigation

In a development that highlights compliance obligations facing centralized cryptocurrency exchanges, Binance supplied Russian authorities with detailed transaction records and personal identification data connected to an active terrorism-financing investigation. According to Reuters reporting, as covered by Cointelegraph, the exchange delivered materials that Russian law enforcement subsequently used to construct a case against an individual accused of funding Ukrainian military operations through cryptocurrency transfers.

The investigation centers on Yuri Belenkiy, an IT specialist detained by Russian authorities in September 2025 who currently awaits trial. Russian investigators allege that Belenkiy facilitated cryptocurrency donations totaling more than $700 directed toward the Ukrainian military and an organization that Reuters identified as operating under different designations, including the Azov Brigade and Azov Regiment. These donations reportedly occurred between January 2023 and March 2024, during a period of heightened geopolitical conflict.

Comprehensive Data Disclosure in Law Enforcement Request

When Russian investigative authorities requested Belenkiy’s complete transaction history from Binance, the exchange provided expansive documentation. According to Reuters’ examination of law enforcement materials, Binance delivered transaction records directly connected to the suspected transfers, along with extensive personal identifying information. The disclosure included his date of birth, residential address, telephone number, and passport identification.

The data package extended further to official documents, encompassing copies of both his Russian passport and Bulgarian residency permit. This breadth of information—spanning financial activity, contact details, and official identification—reflects the comprehensive personal and financial profiles that major crypto platforms assemble during user registration and account maintenance procedures.

Exchange Cooperation and Regulatory Compliance Frameworks

Binance formally exited Russian operations in September 2023, having divested its local business to CommEX. Despite this operational withdrawal, the exchange retained user data that remained relevant to ongoing Russian investigations, necessitating compliance with information requests based on its previous market presence.

When questioned regarding the data provision, Binance emphasized its role within legal frameworks. “Binance does not make or enforce the laws of any jurisdiction, determine charges, or decide how any government uses information in legal proceedings,” a company representative told Cointelegraph. “Like other global financial institutions, we cooperate with lawful information requests from law enforcement globally, subject to applicable legal, privacy and regulatory requirements.”

The case illustrates the increasingly complex position of global cryptocurrency exchanges, which must navigate legal compliance requirements across multiple jurisdictions while managing user privacy expectations—particularly in situations involving geopolitically significant cross-border financial activities. This case demonstrates that cryptocurrency users’ transaction data remains discoverable by law enforcement worldwide, regardless of exchange regulatory status, a fundamental consideration for those relying on centralized platforms.
