Coinsbuy loses $8.07 million in coordinated two-blockchain attack

An attacker drained $8.07 million from Coinsbuy on August 9, 2026, in a coordinated assault across two blockchains using the Bridgers cross-chain swapper. The attacker began with a test 5 USDT transaction, then emptied eight TRON wallets of 6.04 million USDT and three Ethereum wallets of 1.89 million USDT and 77 ETH. Coinsbuy refilled the drained wallets within 24 hours, suggesting researchers believe private keys were not compromised.

An attacker drained $8.07 million from Coinsbuy across TRON and Ethereum in under an hour on August 9, 2026, according to CoinDesk's reporting. The assault exposed a novel cross-chain attack vector that bypassed custody controls without compromising private keys, raising questions about how the attacker accessed withdrawal paths on a major exchange.

The breach unfolded in two coordinated phases across separate blockchains. The attacker opened with a 5 USDT test transaction, then emptied eight TRON wallets of 6.04 million USDT. On Ethereum, three wallets were drained of 1.89 million USDT and 77 ETH. Cross-chain swapper Bridgers linked the two operations, per CoinDesk: its Ethereum payout contract sent funds directly into the Ethereum swap wallet, creating a single coordinated attack despite the blockchain separation.

After draining the wallets, the attacker routed approximately 79% of the stolen funds through instant exchange FixedFloat using roughly 50 single-use addresses, according to CoinDesk's analysis. When contacted by Specter Investigations, ChangeNOW froze a six-figure sum of the outflow. Approximately 282 ETH (roughly $542,000) across five addresses remains unmoved as of the reporting date.

The Evening Brief 8:28 PM UTC

Bitcoin spot ETFs posted their strongest weekly inflow since mid-April, $853.54 million for the week ended August 7, 2026, with BlackRock's IBIT drawing $693 million of that total, as the desk reported this morning. The desk's ETF flow board shows the trend carrying into this week: a $101.7 million net inflow on August 7 itself, part of a five-session streak worth $865.3 million combined, though the funds remain $4.5 billion in the red year to date after months of heavier redemptions. Alongside that, leveraged funds on CME have shifted to net long bitcoin futures positioning for the first time in years, according to CryptoQuant CEO Ki Young Ju, per CoinDesk, after the three-month futures basis fell to 3% against 3.8% Treasury yields and eroded the profitability of the basis trade that had kept those funds structurally short.

Not every signal points the same way. Strategy, the bitcoin treasury arm of MicroStrategy, sold 1,690 bitcoin for $108.6 million at an average price of $64,262 to fund a preferred-share repurchase, and separately raised $653.1 million through common stock sales, per CoinDesk. The sale reduced its holdings to 840,447 BTC, which still carry a $75,385 average cost basis, meaning the position sits underwater at the price the company sold into. Hyperliquid's gross protocol revenue fell 43% over four quarters to $202 million in the second quarter, even as the platform's open interest reached $11 billion and it settled roughly 9% of global perpetual positions, up from under 7% in late May; the desk's reporting ties the decline to a fee-sharing model, HIP-3, that has grown builder-deployed markets from 2% of volume at the start of the year to roughly half of it today.

On the infrastructure and security side, a minority Bitcoin fork called BIP-110 produced only two blocks in eight hours before stalling at block 961,633, while the main chain advanced 48 blocks to 961,681 over the same window, exposing how far the proposal fell short of the mining consensus needed to activate cleanly. Coinsbuy lost $8.07 million on August 9 in a coordinated attack across TRON and Ethereum using the Bridgers cross-chain swapper, draining 6.04 million USDT from eight TRON wallets and 1.89 million USDT plus 77 ETH from three Ethereum wallets; Coinsbuy refilled the wallets within 24 hours, which researchers read as evidence private keys were not compromised, though the exact access mechanism remains unexplained.

Institutional adoption continued on two fronts. Mastercard completed its $1.8 billion acquisition of stablecoin infrastructure firm BVNK, beating a reported offer of up to $2.5 billion from Coinbase, with BVNK's founders citing cultural fit over price, following Stripe's $1.1 billion Bridge acquisition in late 2024. T. Rowe Price, which manages $1.9 trillion, launched its actively managed TKNZ multi-token ETF in July, holding roughly 60% in BTC and ETH plus a 1.26% dogecoin allocation that portfolio manager Blue Macellari frames as an infrastructure stress test rather than speculation. Separately, the UK's FCA is consulting institutions on rules for tokenized gold to defend London's 70% share of global OTC gold trading volume, with formal rules expected within the next few months, per the FCA's own timeline cited by CoinDesk.

On drivers, the desk's ETF story links this week's inflow rebound to a weak jobs report and shifting Fed rate expectations, while cautioning that one strong week does not by itself confirm a durable shift in institutional demand against a $4.5 billion year-to-date deficit. The CME positioning flip is tied specifically to the basis trade's collapsing profitability rather than a stated view on price. Hyperliquid's revenue decline is tied to its own fee-sharing architecture cannibalizing the earnings base. The reporting does not say what specifically let the Coinsbuy attacker access withdrawal paths across two chains.

The desk's own boards show a market still cautious by sentiment even as some flow metrics improve. The Fear and Greed Index reads 30, labeled Fear, within its 22-33 range of the past 30 days. Bitcoin trades at $64,030.91, down 1.27% over 24 hours but up 1.8% over seven days and 7.62% over 30, sitting 48.7% below its 12-month high with an RSI of 49. The Whale Watch board shows $60.2 million in net bitcoin value moving off exchanges over the past 24 hours, while stablecoin buying power reads slightly negative at -$36.8 million, meaning marginally more stablecoin value moved onto exchanges than off over the same window; the board's largest single movements were near-matched roughly $499.9 million USDT transfers at Binance in both directions, consistent with exchange rebalancing rather than a clear directional signal. Leverage data on OKX shows a BTC long-short ratio of 1.35 with $12.5 million in long liquidations against $1.9 million in shorts over 23 hours, and total crypto market capitalization at $2.275 trillion, down 1.37% over 24 hours, with bitcoin dominance at 56.5%.

The nearest dated regulatory checkpoint the desk has covered is the CLARITY Act's September 1, 2026 date, following earlier Senate procedural delays that pushed expectations for passage into 2027. On other fronts, watch for the FCA's formal tokenized gold rules, expected within the next few months per its own timeline; Hyperliquid's third-quarter revenue print as a test of whether its fee-sharing model stabilizes; further disclosure from Coinsbuy on how its withdrawal paths were accessed; whether Strategy continues selling bitcoin or reverses toward accumulation; and whether BIP-110 backers attempt a respin, none of which the record currently supports.
