Coldcard 2021 Firmware Vulnerability Led to Over $100 Million in Bitcoin Theft

Odaily News: A 2021 firmware vulnerability in the hardware wallet Coldcard resulted in insufficient randomness in some recovered seeds. Since July 30, attackers have transferred approximately 1,600 to 1,800 BTC from affected wallets, involving thousands of addresses, with an estimated value exceeding $100 million.Coldcard manufacturer Coinkite stated that it must be assumed that someone used AI to review its public firmware. The vulnerability has existed for about five years, and whether AI was involved in the related attacks has not yet been confirmed.Shielded Labs researcher Taylor Hornby used a Claude Opus 4.8 audit agent and discovered a vulnerability in the Zcash Orchard shielded pool circuit dating back to 2022, which in testing could generate unlimited counterfeit ZEC without a trace. Developers completed the fix within days, and no theft of coins has been confirmed.Statistics from blockchain analytics firm Chainalysis show that on-chain writes carrying malware instructions and command-and-control information rose from about 2.06 per day to 11.1 per day, an increase of 440%.

Crypto industry stakeholders submit differentiated rule proposals to SEC on novel ETF regulation

Odaily News Crypto enterprises, asset managers, market makers, and consumer advocacy groups have submitted comments to the U.S. Securities and Exchange Commission (SEC) in response to its request for input on the regulatory framework for "novel ETFs," covering exchange-traded products such as crypto assets, private assets, event contracts, and leveraged strategies.Crypto industry organization Crypto Council for Innovation (CCI) recommended extending certain regulatory accommodations applicable to ETFs to non-ETF exchange-traded products. Venture capital firm Andreessen Horowitz (A16z) stated that the SEC should assess products based on their underlying assets and risk profiles, rather than treating all novel ETFs as a single category.Grayscale opposed adding new portfolio restrictions for mature digital asset products, while Chainalysis suggested leveraging public blockchains to enable real-time monitoring and verifiable disclosures. Kalshi expressed support for including event contracts in registered funds, whereas consumer advocacy group Public Citizen opposed offering event contract ETFs to retail investors. The SEC will evaluate whether to adopt a unified regulatory framework or craft separate rules based on product structure and risk. (Decrypt)

Iranian Rial Hits Record Low, US Sanctions Target Digital Assets for First Time

According to Odaily, the Iranian rial hit a record low this week, with the open market exchange rate falling to approximately 2.02 million rials per US dollar on August 24, compared to around 1.53 million rials in the first quarter. During the same period, the US government launched "Operation Economic Exodus," adding more than 60 entities to the Treasury Department's blacklist and, for the first time, designating digital assets as a sanctionable category.State-controlled farms linked to Iran's Islamic Revolutionary Guard Corps (IRGC) control approximately 65% of Iran's Bitcoin mining capacity. Iranian miners have accounted for roughly 3% to 7% of global Bitcoin hashrate since 2019, with the mined Bitcoin valued at an estimated $1.35 billion to $3.15 billion at various stages.Iran legalized Bitcoin mining in 2019, allowing licensed operators to use industrial electricity at approximately $0.004 per kilowatt-hour and sell the mined tokens to the Central Bank of Iran. Chainalysis estimates that IRGC-affiliated wallets received over $3 billion in Q4 2025; Elliptic states that the Central Bank of Iran holds at least $507 million in USDT.The US Treasury sanctioned Nobitex, Wallex, Bitpin, and Ramzinex in June. Nobitex had processed more than half of Iran's digital asset inflows; in April, the US Treasury seized nearly $500 million in Iran-linked crypto assets. (Bitcoin.com News)

Crypto Violent Heists Exceed $30 Million in 2026, France Becomes a Hard-Hit Area

According to The Block, data from blockchain analytics firm Chainalysis shows that violent robberies targeting cryptocurrency holders in the first half of 2026 have resulted in losses exceeding $30 million. If the trend continues in the second half, the full-year total will surpass the historical peak of $58 million in 2025. France has become the world's largest "Wrench Attack" hotspot, with 30 public cases recorded in the first half of 2026, while the French Minister of the Interior stated that actual cases exceed 70. Chainalysis attributes this to the 2024 French tax authority data breach—a tax official was suspected of stealing and selling the names, addresses, holdings, and tax records of high-net-worth crypto holders, causing the attack frequency to surge from a monthly average of 1.9 in 2025 to a monthly average of 4.6 in the first half of 2026. Attack methods have also deteriorated; cases targeting family members rather than the holders themselves now account for over 40% of French cases, and the proportion of home invasions rose from 14% in 2025 to 37%. Stolen funds are typically quickly moved on-chain, with some laundered through tools such as decentralized exchanges and cross-chain bridges; advanced criminal networks are even linked to cartel money laundering and terrorist financing channels.
