Kyrgyzstan: Crypto Conduit for Russia
Russia is turning to crypto platforms in its central Asian, former Soviet neighbor of Kyrgyzstan to evade sanctions and procure dual-use goods to fuel its ongoing invasion of Ukraine, finds analysis from TRM Labs.
Kyrgyzstan drew closer to Russia following the Kremlin’s war of conquest against Kyiv while simultaneously emerging as a global crypto hub. TRM says it’s unclear whether the Kyrgyzstan is being exploited by Russia as a money laundering destination or is complicit – meaning there are steps the government could take if it truly wanted to crack down on suspicious trades. One key step would be strengthen the requirement for registering virtual asset service providers and mandating more transparency about funding sources.
Many Kyrgyzstan VASPs reuse the same address, contact information, founders and infrastructure, “classic hallmarks of a coordinated network designed to obfuscate illicit flows,” TRM wrote.
TRM also spotted “a distinctive transaction pattern” associated with wallet addresses used by Garantex, the sanction Russian crypto exchange targeted for a takedown earlier this year by an international police operation (see: Cryptohack Roundup: Garantex Operator Arrested).
“Governments and law enforcement agencies seeking to counter Russia’s sanctions evasion toolkit need to urgently engage directly with Kyrgyz authorities on compliance,” TRM urged. Without intervention, the Kyrgyzstan model could be duplicated elsewhere, as already appears to be occurring in Kazakhstan and Uzbekistan.
CoinDCX Loses $44M in Hack
Indian crypto exchange CoinDCX suffered a $44 million hack, marking one of the country’s largest crypto breaches since WazirX’s $230 million exploit led to collapse last year. The breach was first flagged by blockchain investigator ZachXBT, who linked the compromised wallet to CoinDCX and traced the attacker’s movements across Solana and Ethereum, originating with funds from Tornado Cash.
CoinDCX CEO Sumit Gupta confirmed the incident, citing a “sophisticated server breach” that impacted a liquidity provisioning account on a partner exchange. He said that customer funds were safe and unaffected and that the platform would cover the loss from its own reserves. CoinDCX is now working with partners to recover the stolen assets and plans to launch a bug bounty program.
US Seeks $7.1M in Crypto Linked to Oil Tank Investment Scam
U.S. federal prosecutors in Washington State are pursuing $7.1 million in cryptocurrency connected to an alleged oil and gas investment scam. Prosecutors filed a civil action to seize the funds, which authorities say were laundered through multiple crypto wallets in an attempt to hide stolen money.
The indictment shows Geoffrey K. Auyeung, 47, and unnamed co-conspirators, misled victims into wiring funds to supposed escrow accounts for oil tank storage deals in Rotterdam or Houston. Instead of investing, the funds were distributed across 81 bank accounts and 19 crypto wallets holding bitcoin, USDT, USDC and ETH.
Authorities had already seized $2.3 million from Auyeung’s accounts at the time of his arrest in 2024, and he now faces multiple money laundering charges.
Ex-NCA Officer Jailed for Stealing Seized Bitcoin
Former U.K. National Crime Agency officer Paul Chowles received a five year and six months prison sentence for stealing 50 bitcoins – now valued at $5.9 million – from assets seized during a joint NCA-FBI investigation. The 42-year-old from Bristol was the analyst in charge of managing the seized cryptocurrency in a 2017 operation that led to the conviction of Liverpool-based criminal Thomas White.
Chowles siphoned off the BTC, split it into smaller amounts and laundered it through mixing services like Bitcoin Fog. He later converted some of the funds into cash or spent them through debit cards. Merseyside Police arrested him in 2022. He pleaded guilty in May to theft and money laundering.
Crypto Theft Hit $2.17B in First Half of 2025, on Track for $4B by Year-End
Crypto-related thefts surged to $2.17 billion in the first half of 2025, already surpassing last year’s total, showed a mid-year report by Chainalysis. The bulk of the losses stem from a $1.5 billion hack on Bybit in March – the largest crypto heist ever – which U.S. authorities linked to North Korean state actors.
Service-based attacks still dominate, but Chainalysis said thefts targeting individuals are growing, making up nearly a quarter of all stolen funds. Cybercriminals are deploying deepfakes, social engineering and one-click malware to breach personal wallets, while violent “wrench attacks” are also on the rise.
Thieves are paying hefty fees – over 14 times the norm – to obscure transactions through mixers and cross-chain bridges.
Trump Media Reveals $2B Bitcoin Holdings Amid Aggressive Crypto Push
Trump Media & Technology Group, parent company of Truth Social, said its bitcoin treasury program now holds $2 billion in BTC and bitcoin-related securities, making up about two-thirds of its $3 billion in liquid assets.
The disclosure follows a Financial Times report in May suggesting the company planned to raise $3 billion for a crypto strategy, a claim the firm initially dismissed. The latest update confirms Trump Media has actively deployed capital into the crypto space and allocated $300 million toward options tied to bitcoin-linked equities, which it may convert into spot bitcoin based on market trends.
The company did not specify how much of the $2 billion represents direct bitcoin holdings versus ETFs or equities.
