Binance Shared Donor Data with Russia in Ukraine Case

Binance data reportedly used in terrorism financing case

A Reuters probe published Aug. 17, 2026, says Binance supplied Russian investigators with identity documents and cryptocurrency transaction records that were later cited in a terrorism financing prosecution against Russian IT specialist Yuri Belenkiy. According to the reporting, the exchange’s response to a 2025 legal request included personal information and records of transfers linked to donation campaigns supporting Ukraine.

This development raises urgent questions about compliance, cross-border data transfers, and the responsibilities of centralized crypto exchanges when responding to law enforcement demands — particularly in politically sensitive cases involving donations, sanctions, or alleged terrorism financing.

Who is Yuri Belenkiy and what are the charges?

Yuri Belenkiy, 49, is accused by Russian authorities of sending more than $700 in cryptocurrency to organizations tied to Ukraine’s military. Prosecutors have used transaction records allegedly obtained from Binance to support terrorism financing charges. Belenkiy remains detained pending trial. Reuters reports that neither the defendant’s lawyer nor Russian officials provided substantive comment on the exchange’s reported role.

What Binance allegedly disclosed

Reuters says the exchange provided a data file that included Belenkiy’s identifying details — reportedly his address, phone number, date of birth, passport and Bulgarian residency permit — together with a history of transfers. The records reportedly confirmed payments to a wallet publicized by exiled Kremlin critic Arkady Babchenko during fundraising appeals for medical supplies for Ukrainian soldiers, as well as transfers to an organization linked by Russian authorities to the Azov Brigade.

The Investigative Committee of Russia used those records in an interim case outline sent to the prosecutor general, Reuters reports, citing documents that list Binance transaction data among the grounds for pursuing terrorism financing charges.

Why the transfers matter legally

Russian authorities treat Azov and some associated groups as terrorist organizations. Other states do not share this classification, and humanitarian or donation campaigns linked to Ukraine are generally not designated as terrorism in much of the West. For prosecutors in Moscow, however, evidence that a domestic citizen moved funds to wallets associated with these campaigns became a central piece of a criminal case.

The provenance of on-chain donations can be difficult to interpret: public wallet addresses, social media appeals, and voluntary donor transfers do not automatically demonstrate criminal intent. But exchange-provided records that connect a real-world identity to anonymous wallets can be decisive in building a legal narrative.

Binance’s response and the company’s stated policy

Binance declined to discuss the confidential request or specific details about Belenkiy’s case. The exchange told Reuters it cooperates with lawful global law enforcement requests “subject to applicable legal, privacy and regulatory requirements,” adding that it does not determine national laws or how courts will use information once disclosed.

An official Binance support page instructs Russian and Belarusian law enforcement to send records requests to [email protected]. Reuters says the Investigative Committee received two replies from that address, though the company has not publicly identified which Binance legal entity processed the 2025 request or which national law provided the legal basis for the disclosure.

Operational presence vs. data responsiveness

Binance announced in September 2023 that it would exit Russia by selling its local operations to CommEX, saying continued operation in the market was inconsistent with its compliance strategy. Binance maintained the transition would include no continuing revenue share or repurchase option and expected customer migration to conclude within roughly a year.

Legal analysts told Reuters that even after leaving an operational market, a company may retain historical customer records and respond to formal information requests. That means an exit does not automatically eliminate the possibility of subsequent disclosures to local authorities. Still, critics argue that Binance had no obligation to process Russian requests after its announced withdrawal; Binance disputes that interpretation but has not specified the legal authority used for the transfer in Belenkiy’s case.

GDPR, cross-border data transfers and unresolved legal questions

Belenkiy reportedly holds a Russian passport and a Bulgarian residency permit. If he registered on Binance using EU residency credentials, European data-protection rules — including GDPR requirements — could apply to transfers of his personal data outside the European Economic Area. Under GDPR, transfers to a third country lacking an adequacy finding (such as Russia) require robust legal safeguards and a clear legal basis.

Attorney Mike Bystrov told Reuters that EU privacy protections “may” have restricted Binance from disclosing personal data to Russian authorities without appropriate safeguards. Reuters said it could not confirm whether Belenkiy’s account was registered in Bulgaria or which Binance entity controlled his data; those determinations would be central to any regulatory review.

The European Data Protection Board declined to comment on the specific case; enforcement would fall to national data protection authorities. Bulgaria’s regulator did not respond to Reuters’ requests for information.

Potential regulatory and legal outcomes

Any GDPR or privacy probe would need to resolve where Belenkiy’s account was registered, which Binance legal entity held his records, and the precise legal instrument used to justify the transfer. Those technical jurisdictional facts determine whether a European regulator could open a breach investigation and whether the exchange adhered to cross-border transfer rules.

Independently, Russian criminal proceedings will proceed on their own timetable. The criminal court may examine the disclosed transfers, along with other evidence, when Belenkiy’s trial begins.

Wider implications for crypto exchanges and donor transparency

This case underscores the tension facing centralized crypto platforms: exchanges operate under multiple legal regimes and are routinely asked by police and prosecutors to provide identity and transaction data. Requests tied to alleged terrorism or sanctions violations can be straightforward when they follow established legal channels — yet politically sensitive cases risk criticism when information disclosed by private companies helps convict citizens for acts that many outside Russia regard as humanitarian giving.

For donors and activists who use cryptocurrency to support politically charged causes, centralized exchanges remain the weak link: KYC (know-your-customer) controls and custodial on-ramps can transform pseudonymous on-chain donations into traceable, real-world identities.

What’s next for Binance and the Belenkiy matter?

Yuri Belenkiy remains detained and has not yet faced a public trial date. Reuters could not establish whether Binance was the only exchange whose records were used or whether Russian authorities have initiated parallel inquiries against other donors. The legal and regulatory scrutiny of Binance’s global compliance practices will likely continue: the company has faced multiple inquiries into sanctions and AML processes, and its CEO has publicly defended the exchange’s cooperation with law enforcement worldwide.

For regulators, the key questions will focus on jurisdictional authority, data-controller responsibilities, and whether transfers complied with applicable privacy rules. For users, the case is a reminder that centralized exchanges can and do respond to lawful requests — and that using noncustodial services or privacy-minded tools may be the only guaranteed way to retain anonymity when donating to polarizing causes.

This story reflects Reuters’ reporting and consolidates legal and technical considerations relevant to crypto exchanges, cross-border data transfers, and donor privacy. We will continue to monitor any new filings, regulatory action, or official statements related to the Belenkiy case and Binance’s disclosure practices.
