A mix of security incidents, regulatory actions and large institutional transactions shaped the day in crypto: a major blockchain rollback after an exploit, a reported handover of exchange data to Russian authorities, a significant broker data breach, fines under MiCA and major asset moves by institutional holders.
Harmony rolls back after exploit that forged trillions of ONE
The Harmony blockchain will roll back its network to the state prior to a recent exploit that resulted in the forging of more than 3 trillion ONE tokens. The Harmony team decided a rollback was the "fairer" solution after one wallet moved nearly 2.4 trillion ONE—about $3 billion in value—within less than two minutes. The underlying flaw was traced to a verification error between shards and has already been fixed.
Binance data used in a Russian terror financing case
Reuters reported that Binance provided Russian authorities with transaction data and customer documents used in a terrorist financing case against Yuri Belenkiy, who allegedly sent over $700 in crypto to Ukrainian organisations. Authorities reportedly obtained identifying information such as address and passport number. Binance said it is cooperating with legitimate requests from authorities and has not commented further on the specific case.
Bits of Gold discloses large customer data breach
Israeli crypto broker Bits of Gold announced that a hacker obtained data for around 200,000 customers after compromising a third-party data analytics provider. Exposed fields included names, ID numbers and bank account details, while the company said funds and private keys were not affected. The incident follows two other industry breaches this week involving SafePal and Trezor.
Institutional moves: Strategy, Bitmine and Tom Lee’s vault
Strategy sold 3.46 million shares of MicroStrategy (MSTR) for $333.7 million and did not buy or sell any Bitcoin in the same week. Proceeds covered dividends, STRC buybacks, and increased reserves by $149.1 million to $4.8 billion; Strategy’s reserves remain at 840,447 BTC, valued at $53.4 billion. Separately, Tom Lee’s Bitmine bought another 9,926 ETH—about $19 million—bringing its holdings to 5.82 million ETH, or roughly $11 billion, reaching 96% of its goal to own 5% of the Ethereum supply; Bitmine also holds 210 BTC and repurchased 1.7 million of its own shares in the last week.
Kraken parent adopts Anthropic’s Glasswing AI for security
Payward, the parent company of Kraken, has joined Anthropic’s Project Glasswing and is using the Claude Mythos 5 model for vulnerability detection, becoming the first known crypto company to access the model. Co-CEO Arjun Sethi framed the move as part of a trend where AI is reversing a security asymmetry, following a letter from more than 40 Bitcoin companies asking AI labs to prioritise defence research.
Goldman Sachs sees Fed rate hike unlikely in September; BTC rebounds
Goldman Sachs said a September Federal Reserve rate hike is "highly unlikely," pointing to weak retail sales and employment data. CME FedWatch implied the odds of a 25 basis point hike fell to 30%. Bitcoin had dipped below $63,000 over the weekend but recovered on Monday.
Bitpanda fined under MiCA for disclosure shortcomings
Austria’s financial regulator, the FMA, fined Bitpanda €70,000 for violations of the Markets in Crypto‑Assets (MiCA) framework in its first public sanction. The FMA cited a late filing of a white paper and the distribution of promotional materials without required disclosures. Bitpanda said the issues were related to timing and formal requirements and that there was no impact on customers.
What it adds up to
Together these stories underscore persistent security and privacy challenges across the crypto ecosystem, from smart‑contract and shard verification failures to third‑party data exposures, even as institutional actors adjust balance sheets and firms explore AI tools for defence. Regulatory enforcement under MiCA is beginning to show up in public fines, while macroeconomic signals continue to influence market moves.
