How a former crypto user’s archived Binance data ended up in a foreign terrorism prosecution
When Russian investigators detained IT specialist Yuri Belenkiy in September 2025, Binance had been formally out of Russia for nearly two years. Its buyer data, nevertheless, had been nonetheless obtainable.
Law enforcement paperwork reviewed by Reuters present that Binance provided private and transaction data later included into a Russian terrorism-financing case towards Belenkiy.
The 49-year-old Russian passport holder, who additionally has a Bulgarian residence allow, is accused of sending greater than $700 in crypto to Ukrainian recipients between January 2023 and March 2024. Russian authorities say the funds supported a group linked to the Azov navy unit, which Moscow designates as a terrorist group.
Belenkiy is in a Russian jail awaiting trial, and the allegations haven’t been adjudicated.
The case exposes a laborious restrict to what an change exit means for its former clients. An organization can promote its native operation, cease onboarding customers, and take away its workers. It should retain years of passports, addresses, and account histories as a result of monetary regulation requires recordkeeping. Those recordsdata can be found and accessible lengthy after the business relationship that created them ends.
Withdrawing crypto may finish the custody relationship, however copies of the identification and transaction data already submitted can keep behind.
The enterprise left, however the archive stayed
Binance announced the sale of its Russian business to CommEX on Sept. 27, 2023. It introduced the deal as a full exit, stated working in Russia not match its compliance technique and denied any persevering with income cut up or buyback possibility. CryptoSlate’s reporting on the time described the sale and Binance’s denial of ownership ties to CommEX.
The paperwork reviewed by Reuters describe a later regulation enforcement request for transaction data linked with Belenkiy. A response despatched from an handle utilizing the area binanceholdings.ru included a file along with his date of beginning, residential handle, cellphone quantity, and passport quantity. It additionally contained copies of his passport and Bulgarian residence allow, in line with the report.
Russian investigators folded the transaction historical past into their case. One request additionally sought particulars of different Binance clients who transferred funds to the identical pockets. Reuters couldn’t set up whether or not Binance recognized any of these customers.
| Date | Event |
|---|---|
| Sept. 27, 2023 | Binance proclaims sale of its complete Russian enterprise to CommEX |
| January 2023 to March 2024 | Transactions cited by Russian authorities happen |
| September 2025 | Russian authorities detain Belenkiy |
| October 2025 | Investigative Committee presents terrorism-financing allegation |
| 2025 request interval | Binance buyer and transaction data enter the investigative file |
The paperwork cease in need of establishing that Binance secretly saved working its previous Russian change. Data cooperation and buyer servicing, nevertheless, are completely different actions. The greatest lesson right here is that the sensible actuality of leaving a jurisdiction relies upon closely on which layer is examined.
An working exit can finish new accounts and buying and selling. A company exit can take away the native entity or workers. A data exit would require deletion, switch, or authorized isolation of historic data. Financial firms not often promise the final one as a result of anti-money laundering and record-retention guidelines typically require them to protect buyer materials.
Binance advised Reuters that it cooperates with lawful regulation enforcement requests below relevant authorized, privateness and regulatory necessities. The change additionally stated it doesn’t resolve what costs authorities file or how they use info as soon as produced.
Its public government law enforcement guidelines say officers should present supporting paperwork and a legitimate courtroom order, police order, or warrant from a competent jurisdiction. Requests should state their authorized foundation. Binance says it might require extra info to verify that disclosure is lawful and should notify the consumer except a legitimate order or warrant bars discover. Preservation requests maintain data for 90 days and could be renewed.
Those procedures clarify how disclosure is meant to work. The public report does not set up which Binance authorized entity managed Belenkiy’s account, which regulation compelled the manufacturing, or whether or not he acquired discover.
KYC turns a public transaction into a named historical past
A blockchain data transfers below addresses quite than passport names. That pseudonymity could be highly effective till an handle touches a centralized change.
An change’s know-your-customer file provides the lacking key. It can join a pockets or deposit handle to a identify, cellphone quantity, handle, doc picture, and machine data. Internal transaction data can add the route between an on-chain switch and an change account. Once the identification file and public ledger are joined, investigators can reconstruct exercise that occurred years earlier.
That’s the crypto privateness paradox that regulation created. Governments required centralized exchanges to gather extra figuring out data to discourage cash laundering, sanctions evasion and fraud. The similar system produces a sturdy archive that can be utilized in tax instances, political investigations, or prosecutions below nationwide safety legal guidelines.
The permanence works in each instructions. A blockchain can protect proof of felony finance. It may also protect a lawful donation that a authorities later classifies as felony, however the ledger can not inform these makes use of aside. The authorized system that attaches a identify and offense to the switch does that.
Belenkiy’s case is particularly delicate as a result of Russian authorities classify Azov as a terrorist group and deal with associated help accordingly. A donation framed elsewhere as help to Ukraine can carry a radically completely different authorized that means inside Russia. Binance’s function was to supply data, to not make that classification.
This is why modernized identification methods have gotten central to crypto coverage. CryptoSlate has coated proposals to make use of zero-knowledge proofs for financial compliance, permitting a buyer to show an attribute with out handing each verifier a reusable copy of the underlying doc. Such methods protect lawful disclosure whereas lowering what number of full identification recordsdata exist throughout intermediaries.
Privacy rights do not assure deletion
Belenkiy’s Bulgarian residence allow provides an unresolved European difficulty. A residence card alone can not set up that he was a buyer of an EU Binance entity or that the General Data Protection Regulation (GDPR) ruled the disclosure. Reuters could not decide his registration entity, so the obtainable details provide no foundation for alleging that Binance violated EU regulation.
If an EU entity managed the account, GDPR guidelines would nonetheless require a authorized foundation and safeguards for sending private data outdoors the bloc. The European Commission’s guidance on international transfers explains that European protections can comply with the data. Companies want an adequacy resolution, authorised safeguards, or a legitimate derogation.
Nor does GDPR create an unconditional proper to erase an previous change account. The Commission’s explanation of individual rights says erasure could be refused when processing is required by regulation or wanted for authorized claims. Its instance is a financial institution that should retain former buyer particulars for 10 years even when the client asks for deletion.
That distinction leaves customers with two very completely different types of management. Moving cash to self-custody removes the change from future custody and may restrict new account data. Closing an account might cease future use. Neither motion erases transactions already written to a public chain or data an middleman should legally maintain.
Binance’s Russian exit was actual on the degree it introduced: it bought the enterprise and wound down native service. Belenkiy’s prosecution exposes the additional layer carried by former clients. Companies go away markets on a company timetable. Personal data leaves, if it leaves in any respect, on a authorized one.
