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%.

Korean stock market forced liquidation volume reaches 344.2 billion KRW in July, credit leverage risks continue to escalate
According to data from the Korea Financial Investment Association, driven by a significant downturn in the stock market, on-exchange credit leverage has entered a phase of concentrated deleveraging. The cumulative forced liquidation amount for July has already reached 344.2 billion KRW, with a single-day liquidation volume of 142.2 billion KRW on July 9 alone. Due to a two-trading-day delay in the reporting of liquidation data, the clearing pressure triggered by the sharp drop in the KOSPI on the 13th has not yet been fully reflected in the statistics, leading market forecasts to anticipate a further increase in subsequent liquidation volumes.On July 13, the Korean stock market experienced severe volatility, with the KOSPI closing down 8.95% and triggering both the Sidecar selling suspension mechanism and a Level 1 circuit breaker during the session. The semiconductor sector led the decline, with SK Hynix falling 15.37%, marking its largest single-day drop in history, while Samsung Electronics closed down 10.7%. Currently, the margin balances and credit financing balances of Korean retail investors continue to shrink, with the market entrenched in a negative deleveraging cycle of "falling stock prices → forced liquidation → further decline in stock prices."

IMF Warns: Tokenized Assets Reach $65.1 Billion, Automatic Liquidation Could Amplify Financial Shocks
Odaily News: The International Monetary Fund (IMF) noted in Chapter 3 of its October 2026 Global Financial Stability Report that, as of July 31, excluding repurchase agreements and stablecoins, the scale of tokenized real-world assets reached approximately $65.1 billion, including $30.4 billion in tokenized credit, $17.5 billion in money market funds, and $2.3 billion in tokenized equities.The report pointed out that automatic liquidation, instant settlement, continuous trading, and programmable collateral could accelerate forced liquidations and amplify financial shocks when markets come under stress. The cross-platform reuse of collateral could also increase leverage, causing risks to transmit more rapidly across different institutions and markets.The IMF identified legal certainty, regulatory clarity, blockchain network interoperability, and reliable settlement assets as four obstacles to the broader adoption of tokenized markets, and recommended adopting technology-neutral regulation, strengthening oversight, implementing circuit breakers, and preventing instability from automatic liquidation.

Lula's Upset Re-election Victory Triggers Market Panic, Brazil's Stocks, Currency, and Bonds May Face Selloff, Stock Market at Risk of Circuit Breaker
Odaily reports: Brazilian President Lula won a fourth presidential term with 51.8% of the vote in the second round of the presidential election. The election result came as a surprise to the market, and Brazilian stocks, bonds, and the real exchange rate are facing selling pressure.Early trading indications showed that perpetual contracts linked to the iShares MSCI Brazil ETF (EWZ) on Hyperliquid fell as much as 27%, while real currency derivative contracts on the Chicago Mercantile Exchange (CME) indicated that the real could weaken to 5.55 per dollar, implying a decline of more than 10% from last Friday's closing level. Brazilian domestic trading institutions warned that selling pressure after the market opens could trigger circuit breaker mechanisms.Previously, the market widely bet on a Bolsonaro victory, and Brazilian assets rebounded sharply after the first round of voting. Now that the election result has reversed, related trades face liquidation pressure. Analysts noted that the market may reassess Brazil's fiscal outlook, interest rate trajectory, and exchange rate risks in the short term, and that continued escalation of political disputes could further amplify asset volatility.

Garrett Jin: Bitcoin's $80K-$82.5K Range is a Key Resistance Zone, Short-Squeeze Momentum Hard to Sustain
Odaily News, Garrett Jin, proxy for the "BTC OG Insider Whale," analyzed that Bitcoin's latest breakout above $70,000 was driven by multiple bullish factors, including the U.S. Treasury's expanded bond buybacks, the SEC's proposed crypto asset regulatory framework, and the White House crypto summit. The current price has entered a dense overhead supply zone ranging from the mid-$60,000s to the low $80,000s, with the first resistance layer already showing signs of weakening.Garrett Jin pointed out that the significant accumulation of new cost basis in the mid-$60,000 area over the past two months has provided underlying support for this breakout. While the short-squeeze triggered by short liquidations could temporarily push Bitcoin above $80,000 in the near term, the $80,000 to $82,500 range is a critical resistance zone to watch, and the short-squeeze momentum is unlikely to persist. If the market can effectively absorb supply below $80,000 before a breakout, it would be more conducive to a healthier subsequent trend.On the same day, SK Hynix announced South Korea's largest-ever stock buyback and cancellation plan, committing to return at least 50% of its projected free cash flow through 2027 to shareholders. Its shares surged over 10% at one point, triggering a buy-side circuit breaker on South Korea's KOSPI index. Analysts believe this move could alleviate market concerns over declining risk appetite for Korean semiconductor stocks, but it cannot alter the cyclical trajectory of the memory chip industry itself.
A whale shorted Samsung Electronics and SK Hynix on Hyperliquid with 4x leverage, holding a position worth $13 million.
According to Hyperinsight’s monitoring, the Korea Composite Stock Price Index (KOSPI) surged again during trading hours and triggered a circuit breaker. Samsung Electronics and SK Hynix continued their upward momentum, rising 7.5% and 12.9%, respectively. Notably, SK Hynix led the gains, buoyed by positive news of its collaboration with NVIDIA to jointly develop next-generation memory; its share price rebounded above USD 1,400.
Andre Cronje: DeFi Is No Longer Decentralized, Industry Divided Over Security Path Centered on "Circuit Breakers"
Andre Cronje stated most current decentralized finance (DeFi) protocols no longer qualify as "DeFi in the strict sense" and are closer to commercial systems operated by teams. This has sparked industry division over whether "circuit breakers" should be introduced to mitigate attack risks.In an interview, Andre Cronje pointed out that early DeFi centered on immutable smart contracts, but today many protocols rely on upgradeable contracts, multi-signature permissions, off-chain infrastructure, and manual operational processes. In essence, they have transitioned from "immutable public goods" to "operable, for-profit businesses." He noted that against the backdrop of recent security incidents, including DeFi attacks involving approximately $280 million and $293 million, industry risks have expanded from simple smart contract vulnerabilities to "Web2-style risks" such as infrastructure issues, permission controls, and social engineering attacks.Regarding risk management, Cronje's firm Flying Tulip recently introduced circuit breakers that delay or queue withdrawals during abnormal fund outflows, providing an emergency response window of about six hours to prevent systemic bank runs and further losses.However, this mechanism has also sparked controversy. Michael Egorov believes that circuit breakers may introduce new centralized attack surfaces. If controlled by signers or administrators, they could instead become new security vulnerabilities or sources of freezing risk. He emphasized that DeFi design should minimize human intervention rather than increase manual control points. Industry analysts pointed out that this debate essentially reflects how DeFi is shifting from the ideal model of "code is law" toward a practical architecture of "hybrid governance plus operational control," while the security boundaries are being redefined.

Confirmed implant of spy module: Ledger Flex purchased at Singapore airport linked to prior theft of over $86 million in assets
former Mt. Gox CEO Mark Karpelès has publicly confirmed that a Ledger Flex purchased at Metapod in Singapore Changi Airport had a spy module implanted inside it. The device was bought by user Ben Yorke this summer and had never been used before being sent in for teardown due to suspicious scratches on its casing. Photos and videos of the teardown released by Karpelès show an additional circuit board and wiring hidden at the bottom of the device. It is a relatively new version of the implant, capable of eavesdropping on screen communications and other methods to steal users' seed phrases during setup. Previously, Ledger devices purchased through the Malaysian distributor CryptoBilis were also found to have been implanted, leading to the theft of over $86 million in assets. Devices purchased from official European distributors and in the Philippines have also been gradually discovered to show similar signs of implantation. The implants have progressively evolved from early hand-soldered modifications to more covert mass-produced circuit boards.

Eight Banking Trade Associations: CLARITY Act Circuit Breaker Is Not a Safeguard
Odaily News: According to crypto reporter Eleanor Terrett, eight banking trade groups have stated that the deposit outflow "circuit breaker" mechanism added to the new version of the CLARITY Act is not an effective safeguard, because the mechanism would only be triggered after large-scale deposit outflows have already occurred.In a letter to Senate leaders, these groups called for further tightening of provisions related to stablecoin rewards, in order to close loopholes that could allow stablecoin balances to earn interest-like payments.
Research teams including the Ethereum Foundation use AI to optimize algorithms, reducing the resource threshold for quantum cracking of BTC and ETH by 50%
Odaily News: Researchers from institutions including the Ethereum Foundation, Theta Labs, and StarkWare have jointly published a paper, using AI coding agents to deeply optimize the core operations of Shor's algorithm. The computing resources required for a potential quantum attack on Bitcoin and Ethereum (secp256k1 cryptographic system) have been reduced by more than 50% compared to Google's benchmark in March of this year. The number of logical qubits required for the circuit has been compressed to 1,151, and later versions have even been reduced to 813. Although current quantum hardware still cannot directly break public chains, the research shows that pure algorithmic optimization is significantly narrowing the time window for the quantum threat. The researchers emphasize that quantum-resistant upgrades take a long time and cannot be applied retroactively, and the industry needs to prepare defenses in advance. (Coindesk)
Vitalik publishes "Local Mixing" cryptography research: exploring next-generation obfuscation techniques, potentially becoming a new fundamental cryptographic primitive
Odaily News: Ethereum co-founder Vitalik Buterin has published his latest article "Obfuscation (Part 3): Local Mixing," providing an in-depth introduction to an emerging cryptographic obfuscation approach — "Local Mixing" — and describing it as a potential new fundamental cryptographic tool following elliptic curves, RSA, and lattice-based cryptography.Vitalik noted that current mainstream obfuscation techniques primarily rely on complex mathematical assumptions but often incur extremely high computational costs. Local mixing, by contrast, takes a completely different approach. Rather than depending on elliptic curves, large integer factorization, or lattice cryptography, it draws on design principles from symmetric cryptography and hash functions, continuously shuffling, restructuring, and hiding circuit architecture to eliminate information leakage while preserving functionality.He explained that the local mixing technique mainly involves steps such as reversibility, hardening, mixing, splitting, crossing walk, and "gadgetization." By introducing random structures into circuits, rearranging logic gates, and employing nonlinear hiding mechanisms, it makes it difficult for attackers to recover the original computational logic.Vitalik pointed out that the technique remains in its early stages, with security not yet subject to long-term validation, and it still faces challenges such as random attacks and linear analysis. Nevertheless, he believes local mixing represents an entirely new path of cryptographic exploration aimed at building more efficient indistinguishability obfuscation (iO) schemes.He stated that if local mixing achieves a breakthrough, it could lead to new quantum-resistant public-key encryption schemes and advance the development of general-purpose obfuscation techniques. While the field still requires years of cryptanalysis and optimization validation, AI-assisted research could significantly accelerate this maturation process.Vitalik described obfuscation as the "final frontier" of cryptography, as theoretically all other cryptographic primitives can be constructed from obfuscation and one-way functions. Local mixing not only has the potential to reduce the cost of traditional obfuscation schemes but could also become an important direction for future cryptographic infrastructure.

Vitalik: Building a Tor-based "paranoid mode" wrapper for the agent tool pi
Odaily reports: Vitalik posted on X platform stating that he has integrated Wrapped zkAPI, Tor, additional cover traffic, and local LLM prompt rewriting into an OpenAI-compatible daemon, and built a "paranoid mode" wrapper for the agent tool pi. Each conversation is assigned an independent Tor circuit, requests include random cover traffic, zkAPI avoids identity leakage through a payment mechanism, and all prompts are rewritten locally; his agent tool runs in a bwrap sandbox with torsocks layered on top, and all operations go through Tor. This solution already has relatively high usability but increases latency; Vitalik stated that Tor is not an ideal privacy solution in this scenario, and more specialized mix networks may require higher bandwidth overhead and built-in constant cover traffic. Lower mainnet deposit and withdrawal gas costs for zkAPI are coming soon.

Anthropic: Claude Designs More Efficient Quantum Circuits, Reducing the Number of Gates Required for Some Tasks by Up to ~17x
According to a report on Anthropic's official blog on October 16, Anthropic collaborated with researchers from Harvard University to enable Claude to autonomously design quantum circuits. Across eight foundational quantum circuit tasks in fields such as chemistry, optimization, quantum simulation, and number theory, Claude's designs required fewer qubits and gates than previously published state-of-the-art solutions. Elliptic curve point addition is a critical step for quantum algorithms used to break elliptic curve cryptography. Claude successfully implemented a reversible modular inversion that does not require storing branch history. Compared to the previous design using the fewest qubits, the new approach requires 12 percent more qubits but reduces the gate count by approximately 17 times. Within the DQI optimization algorithm, which is considered promising for delivering super-polynomial quantum speedup, Claude redesigned the highest-cost decoding step, cutting the gate count by roughly 12 times compared to Google’s prior solution. The study suggests that such advancements can substantially lower the resources needed for quantum algorithms, potentially accelerating the deployment of practical quantum computers.
