Glassnode: Bitcoin Spot Liquidity Weakness Coupled with ETF Outflows, Slowing Outflow Pace Signals Stabilization

Glassnode pointed out in its latest market report that although Bitcoin has rebounded slightly after retreating from the $65,000 zone last week, it remains clearly range-bound overall. Spot trading volume and on-chain transaction throughput continue to shrink, with market liquidity and participation willingness at low levels. The derivatives market also shows caution, with leverage expanding moderately, but aggressive taker activity in perpetual contracts continues to lean toward the sell side, reflecting more aggressive distribution behavior. Funding rates remain positive, indicating lingering long-side inclination, while the options market continues to price downside protection at a premium above actual volatility levels.Institutional demand has simultaneously weakened, with declining spot ETF volumes compounded by net outflows. Institutional positions are near their cost basis, limiting unrealized profit potential for regulated investors and causing a temporary pause in accumulation momentum. On-chain profitability is under pressure, with a large portion of supply in loss and realized losses consistently exceeding profit-taking.The report also noted that the broader pace of capital outflows has begun to slow, which could be an early signal that selling pressure is stabilizing. The overall market remains caught between short-term selling pressure and relatively resilient long-term holdings. Weak spot liquidity, deteriorating institutional flows, and elevated loss realization collectively point to a continuation of the consolidation pattern, while the slowing outflow pace suggests the market may be approaching a more balanced state before its next directional move.

Approximately 1,700 BTC Stolen by 10 Major COLDCARD Attack Groups, Largest Group Took Over 1,080 BTC

according to Bitcoin News monitoring, analysis by Galaxy Research (@glxyresearch) has identified distinct characteristics among various groups that exploited weakly secured COLDCARD seeds in their attacks. The 10 largest groups alone transferred approximately 1,700 BTC, with the biggest group moving over 1,080 BTC. Researchers differentiated the attackers based on patterns such as fee strategies, transaction timing, fund consolidation methods, and the destinations of the stolen BTC. Several of the largest groups are still suspected to hold nearly all of the stolen BTC. Victims of COLDCARD attacks can contact @intangiblecoins to assist in gathering evidence and reaching out to relevant authorities.

Tornado Cash founder Roman Storm questions DOJ logic, says Google and OpenAI should also be held accountable

Odaily News, Tornado Cash founder Roman Storm stated that if the logic behind the U.S. Department of Justice's (DOJ) case against him holds, tech companies Google and OpenAI should also be held liable for North Korean hackers abusing their products. Those involved reportedly used ChatGPT to write code and Google Gemini for forgery and image manipulation. Storm was convicted in August 2025 of conspiracy to operate an unlicensed money-transmitting business. He pointed out that the Tornado Cash case could set a legal precedent where software developers are penalized for criminal acts committed by users, emphasizing that criminals should be held accountable rather than the developers of tools. The CLARITY Act for digital asset markets is intended to provide protections for software developers by distinguishing developer liability from the potential misuse of protocols for illegal activities. However, although a final motion for consideration of the bill has been scheduled for a vote, its current chances of passage remain low. (Bitcoin News)

COLDCARD hacked, Mk3 user Prince Filip's entire Bitcoin holdings at risk of theft at one point

Bitcoin News posted on X platform saying that Prince Filip learned about the COLDCARD hack while on vacation. As an Mk3 user, he faced the risk of his entire Bitcoin holdings being stolen at any moment.

Loss of approximately $750,000 in BTC: Long-term Bitcoin holder's Google account compromised

Odaily News: Bitcoin News posted on X platform that a long-term Bitcoin holder had all assets withdrawn from their account within less than 12 hours of transferring BTC to a major Australian exchange. According to a friend of the holder, hackers had compromised their Google account for approximately 3 months, obtaining their email and Google Authenticator credentials backed up to the cloud, and then waited for them to deposit BTC into the exchange. The exchange identified the hacker as the account owner and approved the withdrawal, with the holder receiving a withdrawal approval notification at 3 AM. The post recommends disabling cloud backup for Google Authenticator and using hardware security keys such as YubiKey; setting up two keys can serve as a backup in case one is lost.

Galaxy Research Head: Coldcard Incident Shakes Bitcoin Community, Signaling a Turning Point in Security Philosophy

Odaily News, Galaxy Research Head Alex Thorn stated on the X platform that attacks exploiting the Coldcard hardware wallet vulnerability have noticeably declined, but cumulative losses continue to rise as more victims come forward. The impact of this incident on the Bitcoin community is significant, as the victims are primarily long-term BTC holders who adhered to self-custody cold storage principles, rather than those who lost assets due to high-risk trading or DeFi activities.At a scale of $112 million, this incident ranks among the top 20 largest hacks in crypto history and is one of the most severe security breaches in the hardware wallet self-custody sector to date. Bitcoin culture may be entering a new phase—the era of relying solely on ideological advocacy and extreme self-custody promotion is coming to an end. The community needs to place greater emphasis on technical security, lower the barrier to entry for users, and avoid simply shifting the burden of security responsibility onto ordinary users. This crisis may ultimately drive the Bitcoin ecosystem to establish a more mature security framework.Galaxy Research has directly contacted 190 victims and has confirmed with high confidence that the exploit has led to the theft of 1,778.84 BTC (approximately $112.7 million) from over 8,600 addresses. This tally does not yet include certain moderately credible suspicious attack records, such as the unconfirmed "Wave 4." If these potential attack scopes are incorporated, total losses could expand to 2,417.35 BTC (approximately $153 million).Meanwhile, the incident is reshaping market perceptions of self-custody security. Galaxy noted that multisig wallets have emerged as the "winners" of this event, with no stolen transactions traced to multisig wallets so far. Multisig service providers including Casa, Unchained, Nunchuk, and Anchorwatch have all observed a notable increase in user registrations and BTC inflows.

153 compromised addresses hold 132.95 BTC, researchers still unable to reproduce Coldcard attacker's seed

Odaily News, according to Bitcoin News monitoring, new research released by @PraveenPerera shows that the Coldcard attacker appears to have first identified vulnerable addresses, then sorted them by BTC balance, and began transferring funds in batches starting from the addresses with the highest holdings. The actual transfer software used was relatively crude. One address had 225 spendable UTXOs, and the attacker happened to extract the most recent 200, leaving the earliest 25, including one UTXO worth 0.16 BTC. This is fully consistent with the 200-record limit that a blockchain API investigated by the researchers returns by default, suggesting the attacker may have failed to load the next page of data. The software even spent a 294-satoshi UTXO, reportedly increasing transaction fees by approximately 2,040 satoshis, with the spending amount clearly exceeding the UTXO's own value. Based on this, the study's author believes the tool's builder may have a stronger understanding of account balance systems than of Bitcoin's UTXO model. Although the attacker appears to have obtained victims' full seeds, at least 75 BTC remain in other addresses derived from the same seeds. The biggest mystery at present is that 132.95 BTC still remain across the 153 compromised addresses, and researchers have been unable to reproduce the seeds behind these addresses, so they cannot rule out the possibility that the attacker obtained undisclosed private device data or candidate data.

BitMEX will close its platform on September 23, 2026; the exchange invented crypto perpetual swaps

Odaily News: Cryptocurrency exchange BitMEX has announced that it will fully shut down its platform at 4:00 (UTC) on September 23, 2026. BitMEX CEO Peter Wilkinson stated that the exchange has been operating for over 11 years and has never lost customer funds due to hacker attacks during that period. Peter Wilkinson noted that BitMEX failed to keep pace with its competitors, having long focused on derivatives business while failing to offer spot trading, yield products, custody, and stablecoin trading services in a timely manner. The exchange also entered the USDT market relatively late, in 2021. He stated that BitMEX once supported its founding team in pioneering perpetual swaps, a product that has since become one of the highest-trading-volume financial instruments in the crypto industry and is now widely used for leveraged cryptocurrency trading.

Approximately 233,000 Bitcoin moved as a precaution, with around $15 billion involved following the Coldcard exploit

Odaily News: After a firmware vulnerability in Coldcard hardware wallets was exploited, approximately 2,100 Bitcoin were stolen, with losses nearing $130 million. On-chain data shows that in the days surrounding the incident, wallets held by long-term holders transferred out approximately 233,000 Bitcoin, valued at around $15 billion. Casa CEO Nick Neuman stated that some of the transferred funds came from Coldcard users migrating to multi-signature wallets, with Ledger and Trezor users also taking similar measures after the event. During the same period, approximately 22,000 Bitcoin were transferred into exchanges. Coinkite has advised users who generated seed phrases using firmware versions 4.0.1 through 4.1.9 to treat their wallets as compromised and immediately migrate to new seed phrases. These versions cover the period from March 2021 to July 2026. (Decrypt)

Sui Co-Founder Leases Factory to Mass-Produce Quantum-Safe Hardware Wallet Cards, Targeting Key Cost Below $10 Per Card

Odaily News: Kostas Chalkias, co-founder and chief cryptographer of Mysten Labs, the development company behind the Sui blockchain, stated that he has leased a dedicated factory at a secret location and plans to scale up production of quantum-safe hardware wallet cards for Sui. The project aims to keep the cost of a single quantum card key under $10, with NFC quantum signing expected to take 1 to 2 seconds. Chalkias noted that the project is being advanced in his personal time outside of work and may include funding to provide cards for users who cannot afford them. The initiative is partly driven by a recent incident involving Coldcard hardware wallets, though the vulnerability was not a quantum attack. Coldcard manufacturer Coinkite disclosed that a firmware vulnerability in Coldcard, traceable to a 2021 update, bypassed the hardware random number chip and generated keys using a predictable software process linked to device serial numbers. Attackers have been moving funds since July 30, with losses climbing to approximately 2,055 BTC, affecting over 7,700 addresses and nearing a value of $130 million. At the protocol level, Sui plans to integrate two quantum-resistant signature schemes approved by the U.S. National Institute of Standards and Technology (NIST), designed for everyday accounts and high-value Move vaults, respectively. Existing accounts can be rotated to quantum-safe keys based on their original recovery phrases, without needing to migrate to new wallets. (Bitcoin.com News)

Different COLDCARD Mk3 devices may generate the same mnemonic phrase, with approximately 4.5 million possible starting states searchable within 3 seconds

Odaily News: Bitcoin News posted on X platform that a new technical analysis released by @KLoaec shows that some vulnerable COLDCARD Mk3 wallets may be generated from only approximately 4.5 million random number generator starting states, which can be searched in about 3 seconds on a single RTX 4090 GPU. Even accounting for additional uncertainty in each wallet's generation method, an attacker could complete the search in about 50 minutes on a single high-end GPU. More critically, this vulnerability could cause different devices to generate identical mnemonic phrases. Assuming 30,000 Mk3 devices, the analysis estimates that approximately 120 pairs of devices could generate the same random number stream. This collision estimate is theoretical but indicates that duplicate mnemonic generation across different devices may be possible.

Coldcard hack losses estimated at 1,816 BTC, CryptoQuant confirms 1,432

Odaily News: Hardware wallet Coldcard has suffered a hack, with no confirmed total loss amount yet. Blockchain analytics platform CryptoQuant has confirmed losses of 1,432 BTC, while Galaxy Research places a high-confidence minimum estimate at 1,730 BTC. Other analyses suggest the scale of losses could be even higher. Research firm Galaxy Research stated that its earlier estimate of 1,816 BTC represents a potential figure, not a confirmed total. As of Tuesday, the firm's confirmed high-confidence minimum loss stands at 1,730 BTC, with over 450 BTC directly confirmed based on victim reports. Blockchain intelligence firm TRM Labs estimates that the attacker moved approximately 1,816 BTC from more than 5,200 addresses in four phases. CryptoQuant stated that its confirmed figures only include addresses publicly disclosed by victims and verified through on-chain patterns, meaning the tally could rise as more victims come forward with information.

BTCPay Server Hit by Critical Vulnerability Exploit, Supporters Launch Up to 3 BTC Bounty to Recover Stolen Funds

According to The Block, open-source Bitcoin payment processor BTCPay Server disclosed a critical security vulnerability being actively exploited last Friday and urgently requested users to upgrade to version 2.4.2. The vulnerability affects all versions prior to 2.4.2; attackers can use it to steal administrator macaroon authentication credentials of LND nodes, thereby fully controlling the connected Lightning Network wallets. Users such as Foundation and Citadel21 have confirmed that their Lightning node funds were drained, but BTCPay has not publicly disclosed the total amount stolen or the number of affected nodes. Currently, the official release version 2.4.2 has fixed this vulnerability, and on-chain hot wallets are not affected. The BTCPay Server Foundation has donated 0.21 BTC each to security researcher Craig Raw and Bitcoin Red Team to commend their responsible private disclosure of the vulnerability. Meanwhile, BTCPay supporters have promised to provide a bounty incentive of "10% of recovered funds," capped at 3 BTC.

朝鲜黑客组织 Kimsuky将 AI 武器化,针对加密货币领域发动更隐蔽网络攻击

According to Bitcoin.com, cybersecurity company Genians Security Center released an analysis report stating that the North Korean Reconnaissance General Bureau-affiliated hacker group Kimsuky is building and testing an AI-centric cyberattack tool suite. Researchers discovered traces of the deployment of three local AI platforms, Ollama, GPT4All, and Msty, in their infrastructure, as well as AI development framework components such as Microsoft Semantic Kernel and LLaMaSharp, indicating that the organization is systematically developing dedicated AI attack tools rather than just making temporary attempts. Since early 2026, Kimsuky has used high-quality documents created by generative AI for spear-phishing attacks targeting the virtual assets, financial investment, and game development sectors; AI-generated professional documents have significantly reduced the effectiveness of traditional phishing email identification. The attack vector consists of ZIP archives disguised as legitimate documents, containing malicious LNK files that can silently execute PowerShell commands in the background after being triggered.
