A Russian court sentenced Yuri Belenky, director of the IT company DiHouse, to 13 years in prison on terrorism financing charges, Radio Liberty reported on 26 October. The case concerns cryptocurrency donations that investigators believe were meant for Ukraine’s Armed Forces, the outlet said. The court also fined Belenky 500,000 rubles ($6,200), according to the report.

Since 2022, Russian courts have imprisoned Russians and Ukrainians under treason, terrorism, and other national-security laws over donations to Ukrainian causes. Binance, one of the world’s largest cryptocurrency exchanges, left Russia in 2023 but says it cooperates with lawful law-enforcement requests in different countries.

Belenky had lived in Bulgaria with his wife and child since 2015. In September 2025, he traveled to Moscow on business, and police detained him at the airport for allegedly using obscene language, Radio Liberty reported. In court, Belenky denied swearing, but the judge gave him 13 days of administrative detention. On the 10th day of his detention, Russia’s Investigative Committee opened a criminal case against him under an article on terrorism financing, based on a report from the Federal Security Service, according to the report.

Binance shared account records with Russian investigators, rights group says

In October 2025, Russia’s Investigative Committee contacted Binance to request information on six users who had transferred funds to a cryptocurrency wallet published by journalist Arkady Babchenko, the Russian human rights project First Department said on 17 August 2026. The exchange provided investigators with Belenky’s detailed account history, including his personal information, copies of identification documents, and cryptocurrency transaction records, according to the organization. The human rights project said the materials helped investigators identify nine more transfers, which went into the final charge against Belenky. Binance told his lawyer it does not give law enforcement user account data without a court order or an equivalent ruling, the group said.

Belenky’s alleged offense was transferring donations totaling 126,000 rubles ($1,560) between 2022 and 2024 to an account published by Babchenko, Radio Liberty reported. The court ordered that sum confiscated.

The court said the money in Babchenko’s account went to Ukraine’s Armed Forces and the Azov battalion, which Russia designates as a terrorist organization, Radio Liberty reported.

In a statement dated 14 October 2025, Babchenko said he had not received transfers from Belenky to the cryptocurrency wallets he had published. He emphasized that he had raised money for civilian humanitarian needs, not to support the military.

Binance’s exit from Russia and previous data-sharing concerns

In September 2023, Binance announced that it would sell its entire Russian business to cryptocurrency exchange CommEX, according to the company’s website. Operating in Russia was incompatible with Binance’s compliance strategy, the exchange’s chief compliance officer, Noah Perlman, said in the announcement. Binance said it would fully exit the Russian market, receive no share of future revenue from the sale, and retain no option to buy back the business.

CommEX said on 29 September 2023 that it was not owned by Binance but confirmed that it had hired some former Binance employees during the platform’s six-month development, Cointelegraph reported.

UK sanctions crypto exchanges and “A7 network” in crackdown on Russian evasion systems

The exit came after earlier questions about Binance’s dealings with the Russian state. In April 2021, Russian financial intelligence officials met with Binance’s head of Eastern Europe and Russia in Moscow and asked the exchange to provide customer data, including names and addresses, Reuters reported in April 2022. The Binance executive agreed to the request in a message to a business associate, saying he didn’t have “much of a choice,” the outlet said. Binance told Reuters it had never been contacted by Russian authorities about Kremlin critic Alexei Navalny.

In February 2026, 11 US senators asked the Treasury Department and the Justice Department to investigate Binance’s compliance with sanctions and anti-money laundering rules, Cointelegraph reported. They cited reports that about $1.7 billion had moved through Binance to Iran-linked entities, as well as possible activity related to evading Russian sanctions. The senators also warned that Binance payment cards launched in parts of the former Soviet Union could facilitate sanctions evasion. Binance rejected the allegations.

Undercover reporters ordered 500 drone mesh modems from a Chinese firm, which billed them to Russia’s Alabuga drone plant, investigation by The Insider found. The outlet estimates the firm makes about half the high-power mesh modems that let Russia steer its drones deep into Ukraine. The firm’s director also named US company AMD as the source of a key chip, and AMD says it has not sold to the firm.

Geran drones and Banderol drone-missiles have become Russia’s main weapons against Ukraine’s energy grid. Russia began this winter’s strike campaign against that grid in late September, ISW assessed. Ukrainians’ survival this winter depends largely on how fast the West halts mesh modem sales to Russia, the outlet argued.

What a mesh modem does

A mesh modem links drones into one radio network. Each unit relays data for the others, so if one drone is shot down, traffic reroutes through the rest. Information keeps flowing even if nearly 80% of the drones are downed, Ukrainian defense adviser Serhii “Flash” Beskrestnov said in November 2025.

Range is the other half of the threat. One XK F-359 holds a line-of-sight link over 100–300 km, The Insider says. In theory, a couple of relay drones could keep a whole attack on Kyiv connected. Operators can then send new commands in flight and steer around air defenses. Russia’s Gerbera drones, first built as cheap decoys, increasingly carry these modems.

A modem from an upgraded Gerbera

To trace the part, The Insider’s correspondent in Ukraine examined an unmarked mesh modem from an upgraded Gerbera with a vertical tail fin, a version that appeared this summer. The outlet identified it as Xingkai’s XK F-359, the part Ukrainian intelligence and earlier reporting, Euromaidan Press included, had logged as the XK-F358. The Insider calls that label a misidentification.

Next, The Insider and the Nordsint investigative project contacted Xingkai on WeChat, posing as a Russian military supplier based in Alabuga. A company employee who introduced himself as “Jack Jiang” confirmed the firm is the model’s sole maker. The Insider identified him as Jiang Qin, Xingkai’s director and owner.

500 modems, three banks

The reporters then ordered 500 units for delivery to Alabuga, home to the plant that makes most of Russia’s long-range drones. Jiang invoiced 19.5 million yuan, which The Insider put at about $2.87 million. He offered two ways to pay: dollars to Xingkai’s DBS Bank account in Hong Kong, or yuan to his personal Ping An Bank account.

In the chat, the reporters said outright that the end user was a military production facility. Jiang raised no objection, The Insider reported.

Later, after the reporters asked to update the address, Xingkai sent a revised invoice with “Alabuga” spelled in Latin letters. This time, it routed payment to a China Merchants Bank account in the name of a former Xingkai manager. She left a management post at the company in 2025, according to Tesari corporate records cited by The Insider. None of the three banks answered The Insider’s requests for comment.

Jiang also claimed the modem’s programmable chip is made by AMD. Asked for an AMD license, he refused, saying Xingkai buys the chips through a middleman. AMD told The Insider that Xingkai “is not an AMD customer or authorized partner,” and said it had sold the company nothing. AMD added that it bars exports of its products to Russia that violate US export controls and sanctions.

Russia's state-backed payment firm A7 took in at least 283 tons of cash rubles, worth more than $14 billion, between November 2024 and July 2025, and turned much of it into payments to China that hide where the money came from, the International Consortium of Investigative Journalists (ICIJ) and Russian investigative outlet Proekt reported on 21 October, citing leaked internal records.

Cut off from Western banks over its war against Ukraine, Russia now moves money the way drug gangs launder theirs: cash goes in, and clean-looking wire transfers come out abroad. The overlap is literal.

Last year, UK investigators found that a network laundering British drug gangs' cash had bought a Kyrgyz bank that was handling payments for Promsvyazbank, Russia's state defense bank. That same bank co-owns A7, which "is also likely to facilitate cash-based money laundering," anti-money-laundering expert George Voloshin told ICIJ. On 1 October, the US Treasury named A7 a "significant transnational criminal organization." Most of the market cash pays Chinese suppliers, and China supplies about 90% of the high-priority Western-restricted items Russia imports for its weapons. Drone makers working for the Russian army are among A7's clients, Proekt found in April.

From market stalls to a defense bank vault

Much of the cash came from Moscow's giant Sadovod market, where broker teams known as "departments" collect bags of rubles from traders, the records show. Vans take the numbered bags to an A7 office, where about 50 cashiers count the money before it is trucked to Promsvyazbank. The bank vaults it and credits A7. At its peak, A7 handled at least 58 tons of cash a month.

Russia's central bank has flagged the problem itself. Money of unknown origin comes "primarily" from Moscow's wholesale and retail markets and from illegal crypto exchanges, a senior Central Bank official said in September, as quoted by ICIJ.

Clean money for Chinese factories

A7 then orders shell companies outside Russia to pay its clients' suppliers, mostly Chinese exporters. The money moves through Kyrgyzstan, largely via the state-owned Trading Company of the Kyrgyz Republic, and the wire transfers carry no trace of cash or of Russia. The records list accounts at ICBC, Bank of China, Agricultural Bank of China, and China Construction Bank. One $287,000 transfer went through Standard Chartered's Hong Kong branch with "Sadovod" recorded as the client.

Chinese banks began refusing Russia-linked payments in December 2023 under the threat of US secondary sanctions. Stripping the funds of their origin makes them easier for Chinese banks to accept, illicit-finance expert Zachary Tvarozna told ICIJ. "The only company that sees everything is A7 itself," Voloshin said.

A7, Promsvyazbank, the Chinese banks, and Kyrgyzstan's economy ministry did not answer ICIJ's questions. A7 has publicly rejected the US accusations, saying it runs "a modern, multi-tiered compliance system."

Sanctioned, but still moving

A7 launched in late 2024, co-owned by Promsvyazbank and led by Moldovan oligarch Ilan Shor, a "sanctioned and convicted criminal fraudster," according to the US Treasury. Ukraine sanctioned its network in February, and the UK followed in May. A7 claimed to have moved more than 7.5 trillion rubles, about 13% of Russia's 2025 foreign trade transactions, and its network also helped Iran sell oil and buy weapons, the Treasury said.

Sanctions did hit A7's crypto side. Daily volume of its ruble token A7A5 fell 96% from its peak by June 2026, blockchain analytics firm Elliptic found. The cash channel is harder to touch: Western banks can see where A7's money lands, but not where it starts.

Seven tankers made 14 trips from South Korea to Russia's Far East in July and August, carrying more than 176,000 metric tons of fuel, most of it diesel, the Guardian found in a 6 October analysis of port records and ship-tracking data. The UK and EU have sanctioned three of the ships, and one loaded its fuel from another tanker at sea off South Korea instead of at a terminal.

Ukrainian strikes have cut Russia's fuel output as Moscow scrambles for supplies, while fuel loaded at South Korean ports has flowed to Russia. Loadings began to surge in July, the same month South Korean President Lee Jae-myung pledged $100 million for Ukraine's reconstruction, the Guardian reported. That creates a tension in Seoul's policy toward the war: South Korea has provided Ukraine with humanitarian and non-lethal aid but ruled out sending weapons directly, while the fuel trade appears legal under South Korean law even though three of the tankers are under UK and EU sanctions.

Russia imported 368,000 metric tons of oil products by sea in August, 112,000 of them from South Korea, according to Kpler data analyzed by the Centre for Research on Energy and Clean Air (CREA) and cited by the Guardian. CREA's own August report gives 172,000 metric tons in total, including 18,000 from South Korea. Neither explains the gap.

Where the tankers said they were going

The Layla, a tanker under UK and EU sanctions, made two voyages from Ulsan to Vladivostok, carrying a total of 57,000 metric tons of diesel. It left South Korea on 19 July and 10 August. On the first trip, it told South Korean authorities it was bound for Vladivostok; on the second, it declared Niigata, Japan, but sailed to Vladivostok again.

The Astoria, a Russian-flagged tanker under UK, EU, and Australian sanctions, loaded nearly 11,000 metric tons of fuel at Ulsan on 1 August. It declared Japan as its destination but sailed to Vladivostok.

The Chongchon did not berth at a South Korean port. Instead, it took about 26,000 metric tons of fuel from the unsanctioned Celeste I at an anchorage off Yeosu in early August. It declared Singapore as its destination but headed to Vladivostok. The owners and managers of the four tankers did not respond to the Guardian's requests for comment.

Why Russia needs the fuel

Ukrainian drone strikes have severely disrupted Russia's refining capacity, the Guardian reported. In July, Ukraine's General Staff said the strikes had knocked out 42% of Russia's refining capacity, costing the industry billions of dollars.

Russian refinery throughput fell in June to its lowest level in more than 20 years, and diesel output is down nearly 30% from a year earlier, the International Energy Agency said, according to the Guardian.

Russia has also restricted fuel exports to protect domestic supplies, extending its diesel export ban until the end of October; on 2 October, Deputy Prime Minister Alexander Novak said Moscow could consider partially lifting the ban if there was overproduction, according to the Moscow Times.

Responses to the shipments

Seoul's non-lethal aid has included helmets, body armor, and demining vehicles, and in 2023 it pledged $2.3 billion in support, mostly in loans.

Isaac Levi, an analyst at CREA, told the Guardian:

"It is shocking that EU-sanctioned tankers loaded fuel at South Korean ports and carried it to Russia. This undermines the sanctions regime and South Korea's support for Ukraine."

South Korea's Foreign Ministry did not address the shipments or the sanctioned tankers. In a statement, it said the government supports international efforts to help end the war in Ukraine and bring about a peaceful recovery. The ministry said it was strictly enforcing its export controls and had expanded them to cover 1,402 non-strategic items with high potential for diversion to military use. The UK Foreign Office did not answer the Guardian's questions about UK-sanctioned tankers using South Korean ports, saying only that it remains committed to monitoring its sanctions.

Ties between Kyiv and Seoul are also strained over Ukraine's disclosure of its transfer of two North Korean prisoners of war to South Korea, which Seoul said should have remained private.
