Bitcoin News posted on X that researchers claim Tailscale has a critical vulnerability: users with approved access permissions can exploit its built-in SSH to gain root access on devices, and the attack may also spread to other devices on the network. Users running nodes with Tailscale should disable Tailscale SSH and update promptly once a patch is released. Tailscale has not yet responded.
Strive CEO Matt Cole posted a chart of the company's Bitcoin holdings on X, possibly hinting that BTC accumulation data may be disclosed next week, a move that could emulate Strategy founder Michael Saylor.
Galaxy Research has published an analysis stating that over the past three weeks, approximately 40 inscriptions composed of random letters have appeared on the Bitcoin network each day, with content that appears to be encrypted text but is not actually cryptographic information. The relevant addresses had previously inscribed the U.S. Constitution onto the Bitcoin network in May. The study found that after analyzing 562 texts, the frequency distribution of the 26 English letters was nearly uniform, clearly differing from normal English and substitution cipher characteristics; metrics such as word length distribution and repeated word frequency also indicated that these texts were likely generated by a random letter generator.Galaxy Research refers to the operator as "Babel Scribe," believing that the activity is more likely testing a data publishing tool on the Bitcoin mainnet rather than attempting to convey hidden messages. The on-chain transaction structure, the continuous use of change addresses, and the regular timing of publications all display characteristics of automated scripts. Related activities also include test texts, random words in different languages, binary data, and the subsequent inscription of the U.S. Declaration of Independence. It is estimated that the project has transferred in approximately 3.33 million satoshis in total, of which about 24% was used to pay miner fees, with the remaining funds still held in the relevant addresses. The researchers suggest that there is no need to interpret these garbled texts as hidden messages.
BTC critic, gold advocate, and economist Peter Schiff posted on X platform that Bitcoin has finally begun to weaken, and it's hard to believe it held up for so long. Bitcoin has now fallen below $80,000, and the next stop could be $75,000.Peter Schiff stated that if this price level cannot hold today, Bitcoin holders will face a very long weekend, especially ETF investors, since they won't be able to sell until Monday.
According to Odaily, Coinbase announced on X that it has now launched a cryptocurrency price market, where users can trade price predictions for BTC, ETH, or SOL, with timeframes ranging from 15 minutes to daily.
Odaily reports: According to Bitcoin News monitoring, Electrum has disclosed a high-risk security vulnerability in which malicious servers can trick users into sending Bitcoin to an attacker's address when users increase transaction fees. The attacker intercepts broadcast transactions and replaces them in the wallet history with a forged transaction that redirects funds to an address controlled by the attacker. If users increase fees via Replace-by-Fee (RBF), Electrum may sign the malicious transaction. Electrum confirmed receiving two related incident reports, with one user losing funds. The attacker also generated addresses with the same last four characters as the intended recipient addresses. The vulnerability affects versions prior to 4.8.3 and has been fixed in version 4.8.3. Electrum reminds users to update immediately and to verify all recipient addresses and amounts before signing transactions.
Since 2025, as of October 5, Bitcoin treasury companies such as Strategy and Strive have financed the purchase of 135,979 BTC through preferred stock offerings, accounting for more than 0.5% of Bitcoin's maximum supply; the related preferred stock market is approximately $12 billion. Perpetual preferred stock has no fixed maturity date, which can alleviate refinancing pressure and attract yield-oriented investors who are unwilling to hold Bitcoin directly; however, expanding issuance also increases dividend expenses. Sustained financing for Bitcoin purchases depends on preferred stock trading at or near par value. If prices fall below par, the appeal of new issuance may decline, and companies may turn to buybacks. James Butterfill, Head of Research at CoinShares, said Strategy's latest weekly report shows the company spent $193 million to repurchase STRC, bought 267 BTC during the same period, and raised its preferred stock repurchase authorization to $3 billion. Buybacks can reduce future dividend costs but also compete with Bitcoin purchases for capital. Ryan Rasmussen, Head of Research at Bitwise, expects ETFs will remain a larger source of Bitcoin demand over the long term, while perpetual preferred stock covers a different group of yield-oriented investors and provides another source of demand support for the market. Butterfill believes preferred stock may amplify market cycles: when financing conditions are favorable, it supports Bitcoin purchases; when market sentiment weakens, that support may diminish.
Odaily — Digital asset company Tether has announced that 15 Bitcoin mining companies, ASIC manufacturers, and mining pools have committed to jointly building and maintaining integrations for its open-source mining development kit, MDK. MDK aims to unify access methods across different mining infrastructures, enabling developers to build applications and AI automation systems.Participants will develop and maintain MDK Workers, converting their respective hardware, mining pool, or system interfaces into universal interfaces; without needing to replace existing technology, they can also decide which features to open up. Existing applications can connect to different mining environments through MDK.Tether's QVAC mining agent has already connected to mining infrastructure through MDK. MDK version 0.11 will be released on October 23–24 at the Plan ₿ Forum in Lugano, with the first stable version 1.0 planned for launch by the end of 2026. (Tether News)
Odaily reports: Six more companies—U.S. bank Wells Fargo, financial software firm Intuit, and chip design company Arm Holdings—have joined the list of companies opposing the tokenized trading of their shares, bringing the total number of objecting companies to 22. OKXICE, a joint venture between OKX and Intercontinental Exchange (ICE), plans to push forward with tokenized stock trading.OKXICE initially proposed tokenizing 63 stocks and planned to support round-the-clock trading. The interim exemption framework introduced by the U.S. Securities and Exchange Commission (SEC) in September requires that issuers be informed of stock tokenization arrangements in advance and be able to formally raise objections.Andrew Cuomo, a board member of OKX and co-chair of OKXICE as well as former Governor of New York, said some companies may accept tokenization immediately, while others will first observe how things develop. He also noted that investor activity is increasingly crossing borders, while market trading hours remain constrained by traditional time windows. (Bitcoin.com News)
Odaily reports: Bitcoin Core developers have merged a security policy adjustment. For vulnerabilities that can be easily discovered or rediscovered through simple large language model (LLM) prompts, the previous long-term confidential disclosure mechanism will no longer be used. The new rules allow developers to mark such issues as "easy to find" during vulnerability classification, then backport fixes to all still-supported versions and release them as soon as possible through minor version updates, along with a security advisory and some vulnerability details.Previously, Bitcoin Core scheduled disclosure based on vulnerability severity, with medium- and high-risk vulnerabilities usually only made public after the affected versions stopped being maintained. This adjustment stems from AI tools lowering the threshold for vulnerability discovery: in July this year, a Bitcoin Red Team composed of 16 developers used AI models to scan about 390 Bitcoin-related projects and recorded 4,962 findings in one day, of which 85 were listed as critical issues. Developers noted that continuing to extend the confidentiality period for such vulnerabilities can no longer effectively prevent attacks and instead delays the release of fixed versions; however, the new rules also mean that fixes may lack longer testing time. Currently, no vulnerability has been officially marked as falling into the "easy to find" category under the new rules. (CoinDesk)
CoinShares' latest market update indicates that despite risk assets experiencing renewed volatility this week, Bitcoin overall has demonstrated resilience, primarily supported by a rebound in spot demand, improving equity market sentiment, and partial short covering. However, the market is shifting from simply chasing AI narratives to focusing more on corporate earnings realization. Earnings reports from several US companies falling short of expectations have triggered sharp volatility in the stock market, and Bitcoin has similarly faced temporary headwinds.
According to an official announcement, Binance Alpha will delist PTB (Portal to Bitcoin), AA (ARAI), OWL (Owlto Finance), DORA, ELIZAOS (elizaOS), MEMES (memes will continue), and KAKU on October 23 at 17:30. Following the token removal, Binance Alpha will continue to support withdrawals and selling for these tokens.
According to an analysis published by on-chain analyst Darkfost on CryptoQuant, sustained tensions in the Gulf region and escalating Ukrainian attacks on Russian refineries have kept Brent crude prices consistently above $100. High oil prices are cascading into production costs, service prices, and commodities, embedding inflation deeper into the economy. This may drag down economic growth, constrain market liquidity, and particularly pressure high-risk assets such as Bitcoin. Historical data indicates that when Brent crude enters a strong uptrend and trades above its annual average, Bitcoin's momentum typically slows; conversely, sharp declines in oil prices often coincide with Bitcoin rallies. Oil prices saw a brief dip in July, benefiting Bitcoin, but Brent has since staged a strong rebound. Darkfost noted that there is no simple causal relationship between the two; rather, it is the economic environment driven by high oil prices that poses headwinds for risk assets. Although liquidity could rotate across different markets and continue to support Bitcoin's upside, current macroeconomic conditions are unfavorable for fresh liquidity inflows.
Alliance General Partner Imran recently posted on X, sharing his views on a16z crypto's shift toward frontier technology sectors. He noted that a16z provided early endorsement for the crypto industry when Chris Dixon led Coinbase's investment in 2013; Marc Andreessen's 2014 New York Times op-ed "Why Bitcoin Matters" was a key factor that prompted him to transition into the Bitcoin industry. At the time, very few institutions and funds were willing to publicly support crypto, and a16z and USV were the two that took on brand risk.Imran believes that the current development of AI infrastructure has benefited considerably from Bitcoin mining infrastructure and talent flowing from crypto to AI. Shifting toward frontier tech such as robotics, biology, AI, energy, and compute means that the talent and capabilities accumulated in the crypto industry over the past decade can be used to build the entire frontier tech sector. Citing data centers as an example, he noted that public and government resistance to data centers is growing, much like earlier resistance to crypto—yet today nearly all traditional financial institutions have embraced crypto to some extent.
According to Cointelegraph, Bitcoin Core developer Antoine Poinsot stated on Thursday on the bitcoin-dev mailing list that large language models (LLMs) have made certain software vulnerabilities extremely easy to rediscover. Maintaining long-term secrecy is already of limited value and instead delays the release of patched versions, prompting the team to update its vulnerability disclosure policy. The new policy dictates that "easily discoverable" vulnerabilities, which can be identified with minimal cost such as through simple LLM prompts, will be patched as soon as possible across all supported major versions, alongside the simultaneous release of security advisories. Other vulnerabilities will continue to be disclosed based on severity: low-severity vulnerabilities will be disclosed two weeks after the release of the major version containing the fix; medium-to-high-severity vulnerabilities will be disclosed two weeks after the end-of-life (EOL) of the last affected version, typically around one year after the patch release; critical vulnerabilities will be handled through a dedicated process.
Bitcoin Core has adjusted its security vulnerability disclosure policy, defining easily discoverable vulnerabilities as those that can be found through simple large language model prompts, and will release fixes as soon as possible across all major versions still under maintenance, while publishing security advisories.Bitcoin Core developer Antoine Poinsot stated that in the past, vulnerabilities were typically kept confidential during a longer disclosure embargo period to allow users to upgrade, but large language models have lowered the threshold for rediscovering certain vulnerabilities, limiting the protective value of delayed fixes.Low-severity vulnerabilities will be disclosed two weeks after the major version containing the fix is released; medium- and high-severity vulnerabilities will be disclosed two weeks after the affected version reaches end of life, typically about one year after the fix enters a new version. Critical vulnerabilities are not subject to the standard policy and will be handled through ad hoc procedures.In August, the volunteer organization Bitcoin Red Team reported nearly 5,000 potential issues across 390 projects, with about one-fifth having been reproduced at the time. Core Lightning developers that same month asked node operators to upgrade or take nodes offline, and delayed disclosure of technical details for two weeks. (Cointelegraph)
