OnKey founder Yishi posted on platform X to remind users that using older iPhone models as cold wallets for cryptocurrency assets may pose security risks. The checkm8 vulnerability exists in the BootROM of iPhone 4S to iPhone X, and the usbliter8 vulnerability, which was disclosed in June this year, affects iPhone XS, XR, 11 series, and second-generation SE, all involving the device's low-level boot code, which cannot be fixed through iOS system updates. Once an attacker gains physical access to the device, they can execute code via the USB interface before iOS boots, and turning on airplane mode cannot prevent such attacks.Yishi advises that iPhone 11 and earlier models are not recommended for storing mnemonic phrases. Users who have used such devices to save mnemonic phrases should generate a brand new mnemonic phrase in a trusted environment and migrate their assets, rather than just changing the wallet address under the original mnemonic phrase. Additionally, users should promptly update their systems, use more complex device and wallet passwords, avoid charging through public USB interfaces, and be vigilant about potential physical attacks during periods when the device is out of their control for extended periods.Previously, OneKey founder Yishi had posted on platform X suggesting users use iPhones as cold wallets, but only recommended using iPhone 17 or newer models.

Trezor stated that the security team received a responsible disclosure report claiming that a Trezor Safe 5 purchased from the Southeast Asian official distributor CryptoBilis had a hardware trojan implanted internally. The device was acquired through Tokopedia in August 2026, and the report indicated that there was an additional circuit board with a cellular module and antenna between the motherboard and the screen, which could read the screen display content and transmit it externally via mobile network when the device was powered on.Trezor has not yet received the physical device for laboratory verification, but based on customer descriptions and video communications, they consider the report credible and have issued a warning. Trezor stated that there have been no reports of lost devices from users at this time and advised users who purchased devices through CryptoBilis since March 2026 to promptly transfer their assets to a wallet using a new mnemonic phrase, and not to enter existing mnemonic phrases on suspicious devices; affected users can contact the official support to request a replacement device or voucher. Trezor removed CryptoBilis from the official distributor list on October 9.

The founder of hardware wallet company OneKey, Yishi, stated that the security incidents involving Binance and previously Bybit indicate that even if wallet private keys are not leaked, attackers may still steal assets by infiltrating the signature approval system. BlackRock's Bitcoin spot ETF IBIT holds approximately 815,000 BTC, valued at about $63 billion, and is currently primarily custodied by Coinbase.Although IBIT has introduced Anchorage Digital as an additional custodian, there are no plans for asset transfers at this time. Yishi pointed out that BlackRock has not separately purchased insurance for the Bitcoin held by IBIT, and Coinbase's commercial crime insurance coverage is $320 million, shared among multiple clients. The custody agreement stipulates that the liability limit for each cold storage address is $100 million. In the event of a significant theft where assets cannot be recovered or adequate compensation obtained, losses may be borne by ETF holders. There is currently no evidence to suggest that IBIT has become a target of attack.

According to an announcement from the Singapore Police Force's official website, the Singapore police have issued a warning stating that since September 10, they have received at least two reports related to tampered Ledger cryptocurrency hardware wallets, with total losses amounting to approximately 3.5 million Singapore dollars. Preliminary investigations indicate that some Ledger hardware wallets purchased at retail stores in Singapore contained malicious hardware components that could steal users' mnemonic phrases or private keys, and transfer assets without the users' knowledge.The police have contacted Ledger, which is reviewing the related cases, and the investigation is ongoing. The police advise users to stop using suspected tampered devices and to generate new mnemonic phrases with unaffected devices, transferring any remaining assets. Zhao Changpeng shared this news on the X platform, reminding Singapore users to be especially cautious.

Recently, in response to user information leaks and supply chain security risks in the hardware wallet industry, KeyPal, a hardware wallet brand under TokenPocket, announced further enhancements to user privacy protection and data security management mechanisms.KeyPal stated that it has not found any security breaches in its system or customer data leaks; this adjustment is a proactive preventive measure based on changes in industry risks.According to the latest plan, KeyPal aims to delete or anonymize unnecessary customer personal information within 15 days after order completion for orders that have confirmed receipt, completed fulfillment, and have no after-sales disputes or other legitimate retention requirements. The security of hardware wallets not only involves private key protection and transaction signing but also includes the protection of personal information generated during the purchase, delivery, and after-sales service processes.

Heatbit, which previously launched a heater with a built-in Bitcoin mining machine, has announced the release of a heating element for water heaters named Bitwater. This element replaces the resistance wire in standard electric water heater elements with 20 Bitcoin mining chips, using the heat generated by the chips to directly heat the water in the tank. Heatbit stated that this electricity was originally intended for heating water, "the same heat, the same electricity, plus Bitcoin." The company claims that global households use approximately 300 TWh of electricity annually for heating water, which exceeds the entire Bitcoin network's consumption of about 170 TWh, advocating for the decentralization of mining to households.Bitwater uses 20 Bitmain BM1370 chips, with a maximum hash rate of 34 TH/s, a maximum power consumption of 600 watts, and an energy efficiency of 12 joules/TH. Due to water cooling, this element requires no fans and produces no noise. The installation process is DIY: turn off the circuit breaker, drain the tank, unscrew the old element, and then screw in the Bitwater using the included wrench. It is compatible with the one-inch standard interface of 30 to 80-gallon electric water heaters commonly found in the United States and Canada, including brands such as A. O. Smith, Rheem, Bradford White, Whirlpool, and GE, without the need for plumbing modifications or additional circuits.Users can check water temperature, hash rate, and earnings through an app, and choose to mine individually or join a mining pool, with mined Bitcoin sent to an address controlled by the user. The initial "genesis batch" pre-order price is $899, with subsequent batches priced up to $1,299, and pre-orders are refundable, with plans to ship in the first quarter of 2027. Heatbit claims to have tested the entire winter in four and five-person households in New York and Florida. Based on the current hash price of approximately $36.73/PH/s/day, the full load of 34 TH/s could mine Bitcoin worth about $1.25 per day, totaling approximately $455 annually.

Bitcoin News posted on the X platform that DOOM has been successfully ported to the Trezor hardware wallet and is running on it.

Semiconductor analyst Jukan shares a commentary translated into English by him, authored by a salesperson from a local Chinese sell-side institution. The individual states: In mid to late September, hardware quickly transitioned into a downward wave, with China and South Korea adjusting first, experiencing deeper declines and longer durations, followed by Japan, Taiwan, and the semiconductor ETF SOXX weakening subsequently; there is significant divergence in the market regarding whether AI is entering a mid-cycle collapse, but there is less controversy about the industry still advancing.The individual summarizes the views of interviewed investors: High long-term interest rates in the U.S., capital expenditures beginning to rely on external financing and competing for funds in the market, multi-layered leverage accumulation, and tight funding are the main reasons for this round of decline, with companies like CoreWeave experiencing a noticeable deterioration in financing structure and cost burden. Model invocation prices are decreasing, but capital expenditures and supply chain costs are difficult to reduce quickly, making short-term investment returns hard to realize. ASML and TSMC's guidance this season is strong, but near-term pressures cannot be ruled out; the bullwhip effect and differences in value chain levels may cause volatility to be greater than expected.The individual also mentions that use cases beyond coding are emerging in scenarios such as SaaS and AI drug development, which may gradually alleviate investment return concerns and expand demand. His personal judgment: Before more evidence emerges, the current situation resembles a high-volatility phase rather than a collapse that has already begun; the decline may not yet be over, and hardware leadership may give way to applications. Even if control of both houses changes in the midterm elections, the impact may mainly be limited to constraints on certain data center projects, and the U.S. earnings season needs to verify the performance of large technology companies.
