According to Decrypt, privacy-focused Bitcoin wallet Sparrow Wallet released version 2.5.4 on August 28. Developer Craig Raw stated that the update was driven by an AI-assisted code review, with the majority of fixes originating from it. This review was prompted by the recent seed generation code vulnerability exploit affecting Coldcard, as well as the release of unrestricted AI models in China, which has significantly enhanced vulnerability scanning capabilities across large codebases. Key updates include: validating the authenticity of transactions returned by Electrum servers, enforcing stricter BitBox02 hardware wallet security requirements (firmware v9.4.0 or higher required), patching local DNS leaks, and masking sensitive credentials in debug logs. Raw noted that there are no indications of any exploits being leveraged, user funds remain secure, and he still advises all users to update at their earliest convenience.
Bitcoin News posted on X platform, stating that France disclosed this month that its tax administration had been hacked, with data of approximately 678,000 individuals and businesses stolen. The stolen data allegedly includes names, addresses, income, and property information. Analysis of the alleged database found 26,805 records showing income exceeding €100,000, including 386 records exceeding €1 million. According to CertiK data, out of 52 verified cryptocurrency wrench attacks globally in the first half of 2026, France accounted for 33. French prosecutors have also accused a tax department employee of using government databases to identify cryptocurrency investors and selling personal information to criminals involved in physical assaults and extortion. The latest data breach has no publicly linked physical attacks yet, but sensitive financial and location data of hundreds of thousands of people may now no longer be under government control.
According to The Block, StarkWare announced it has successfully executed the first post-quantum Bitcoin transaction. Avihu Levy, Head of Applications, used a "signature grinding" approach to repeatedly generate millions of candidate signatures before the transaction entered the Bitcoin mempool, thereby avoiding the exposure of mathematical data related to public keys that could be exploited by future quantum computers to forge signatures. This method incurs significant computational costs, with a single transaction potentially taking several hours. Because the transaction format is unrecognized by standard Bitcoin nodes, it bypassed the public mempool and was submitted directly to miners for inclusion via MARA’s Slipstream service. StarkWare noted that while this technique can serve as a transitional safeguard, Bitcoin will still require protocol-level upgrades or a hard fork to systematically mitigate quantum computing threats.
According to The Defiant, the Core Lightning (CLN) maintainers for the Bitcoin Lightning Network have notified node operators that if they are unable to upgrade to the upcoming patched version, they should run their nodes offline using the --offline parameter. The team stated it will release binaries containing fixes for multiple disclosed vulnerabilities, but specific vulnerability details will remain confidential for two more weeks; as of press time, the relevant binaries and security advisory have not been published. CLN had previously noted that it received several AI-generated CVE reports over the past ten days, and the team is working with open-source contributors to verify, classify, and patch them. The latest public release is v26.06.6, issued on July 22, and the v26.09 release, originally slated for late September, continues to proceed as planned.
Bitcoin News stated on the X platform that BTC Sessions said their team spent weeks assisting Bitcoin holders affected by the Coldcard vulnerability in moving funds to safety, estimating that tens of millions of dollars worth of Bitcoin were protected during this period. But for many, it was too late. A member of their local Bitcoin community lost 90% of their Bitcoin, and another woman they spoke with lost all of her Bitcoin. BTC Sessions stated that this could be the most severe self-custody incident in Bitcoin's history. BTC Sessions said this experience prompted them to rethink asset custody, with diversified security measures emerging as a key lesson.
: Bitcoin News posted on X that Core Lightning developers have received a large number of AI-generated CVE reports over the past 10 days, and have verified the existence of vulnerabilities that need to be fixed. The team has now escalated its response, will release signed binaries, and will keep vulnerability details confidential for a two-week period. Core Lightning strongly urges all users to upgrade during this period; users who have not upgraded should take their nodes offline. Previous versions, including 26.04, will no longer be supported.
Odaily News reported that Galaxy Research tracking found that 6 bitcoin wallets, dormant since 2011, 2012, and 2014, transferred a total of 553.59 BTC between August 16 and 26, valued at $40.15 million at the time of transfer. Two of the wallets carry the "Salomon Client Dusted" tag linked to a New York lawsuit involving Noah Doe.One of the transfers involved 40 BTC from a wallet dormant since May 28, 2012, with the funds moved on August 26 to German crypto custodian bank Boerse Stuttgart Digital. Calculated at a cost of approximately $5, the funds appreciated by roughly 1,535,911%.The remaining transfers included 212 BTC, 150 BTC, and 132.31 BTC, originating from wallets inactive since 2012, 2014, and 2011, respectively. The Noah Doe lawsuit seeks to declare 39,069 dormant bitcoin addresses in New York State as lost property. Additionally, several long-term holding addresses moved funds following the July Coldcard hardware wallet vulnerability incident. (Decrypt)
Odaily News - Hardware wallet maker BitBox reports that credit card sales in August grew roughly 10x compared to the baseline of previous weeks, with the increase primarily driven by North America. Trezor and OneKey also confirmed rising sales during the same period, though neither disclosed specific figures.Trezor, BitBox, and OneKey have all re-reviewed their seed phrase generation, random number generator, entropy, and firmware verification processes. Trezor plans to conduct penetration testing on core firmware functions and publish related security audit reports. OneKey will strengthen reviews of security-critical code paths and transaction signing processes.Ledger CTO Charles Guillemet stated that AI-assisted attacks mean patch releases, vulnerability disclosures, and user education need to accelerate. Blockstream Jade has released a firmware update containing multiple fixes and recommends users simultaneously update their apps, operating systems, devices, routers, and home appliances.

According to Cointelegraph, the latest statistics from Galaxy Research show that the Coldcard hack involved 8,865 addresses, resulting in the theft of 1,789.28 Bitcoin valued at approximately $114.7 million based on the price at the time of the incident. Of this amount, 1,561 Bitcoin, representing roughly 87.3% of the stolen funds, have not yet been transferred and remain in aggregation or holding addresses controlled by the attackers.
Odaily News According to Galaxy's head of research, the Coldcard vulnerability incident involved 8,865 addresses, resulting in total losses of 1,789.28 BTC, valued at $114.7 million at the time of theft and currently valued at $138.8 million.By address, the median loss per address was 0.00152 BTC, with an average of 0.20184 BTC; the median dormancy period for affected addresses was 3.2 years, with an average of 3.6 years.Among 221 victim reports, the median loss was 1.04272 BTC, with an average of 3.57792 BTC; the median dormancy period was 3.25 years, with an average of 2.99 years. The losses reported by victims amount to 790.72 BTC, accounting for 44.2% of total losses. If medium-confidence losses are included and related losses remain unconfirmed, total losses would reach 1,824 BTC, valued at $140 million based on prices at the time of the incident.
Odaily News: Ethereum client Besu has fixed 5 security vulnerabilities discovered by blockchain security firm CertiK in version 26.7.1 released on July 27, and published 4 detailed security advisories on August 14. Vulnerability details were disclosed after a delay to allow node operators to complete upgrade deployments.Jialiang Chang, Director of Security Engineering and Senior Audit Partner at CertiK, stated that the arrangement of releasing patches first and details later provided an 18-day buffer period, allowing node operators to identify affected deployments, test new versions, and coordinate with validators or consortium participants to complete upgrades.The vulnerabilities involve block broadcast handling, caching of future-height consensus proposals, WebSocket subscription limits, and JSON-RPC filter creation. If left unpatched, attackers could exhaust node memory or thread resources, impacting node availability and consensus processing.Using the Chain Scan methodology, CertiK conducted adversarial testing on peer-to-peer, HTTP RPC, WebSocket RPC, and consensus interfaces in a private multi-node test network, and provided reproducible testing tools to the Besu team. CertiK is updating Chain Scan to expand round-the-clock multi-node testing on public chain networks. (Bitcoin.com News)
Renowned gold bull and economist Peter Schiff posted on social media to refute Bitcoin advocates' strategy of bundling artificial intelligence (AI) with Bitcoin for speculative trading, bluntly stating that AI poses a threat to Bitcoin rather than offering any benefits. Schiff pointed out that AI and Bitcoin compete directly for speculative capital, electricity, and data center resources. More critically, AI could uncover vulnerabilities in Bitcoin's code, cryptographic algorithms, wallets, or network that remain undetected by humans, thereby undermining the foundations of its security and scarcity.
Odaily News: Metaverse gaming platform The Sandbox has confirmed a vulnerability in its cross-chain bridge, allowing attackers to mint unbacked SAND on Base and BNB Smart Chain. Blockchain security firm PeckShield detected on August 21 that two addresses had collectively minted approximately 14.9 billion SAND. The Sandbox subsequently shut down bridging functionality on both networks.The Sandbox stated that the affected assets are bridged assets on Base and BNB Smart Chain, while SAND on Ethereum and Polygon, user wallet assets, and the Ethereum-locked assets backing the token remain unaffected. The proportion of genuinely collateralized assets involved in this incident is less than 0.01% of the total SAND supply.The Sandbox is developing a compensation plan for affected liquidity providers and advises users not to trade SAND on Base or BNB Smart Chain until bridging is restored. Coinbase plans to delist 10 perpetual futures contracts, including SAND, on August 26, with open positions to be automatically settled at that time. (Bitcoin.com News)
The U.S. Department of Justice announced an indictment charging 17 members of Iran's Mabna Institute with long-running cyber intrusion campaigns targeting 144 U.S. universities, 178 foreign universities, at least 42 U.S. companies, 11 foreign companies, and multiple government and non-governmental agencies, resulting in the theft of more than 31 TB of academic data, intellectual property, and sensitive information. The indictment alleges that the group has conducted hacking operations under contract from the Islamic Revolutionary Guard Corps (IRGC) and other Iranian government and university entities since 2013, profiting by compromising accounts, stealing research materials and proprietary data, and selling portions of the illicitly acquired resources. Some individuals involved also participated in the HBO hacking incident, where internal data was exfiltrated and attempts were made to extort approximately $6 million in Bitcoin.
Odaily News: According to on-chain detective Specter's monitoring, the victim claimed that due to a Coldcard hack, funds were transferred from Bitcoin to Ethereum. However, on-chain data shows that the 73 BTC ($4.6 million) originally came from the Whirlpool coin mixer two weeks ago, with some of it bridged to Ethereum and subsequently deposited through a phishing Tornado Cash interface. Two coin mixers were used during the fund transfer process. The individual was also found to have appeared in Telegram groups involving private key searches and brute-force attacks. On-chain detective Specter stated that the victim may be a threat actor, and their funds may have been stolen by another threat actor.
Odaily News: BIP-110 supporters are discussing a hard fork to change the stalled minority chain's mining algorithm from SHA-256d to BLAKE2b. Transaction history before the fork remains shared by both chains. If transaction and signature rules remain consistent, the same transaction could be replayed on the other chain, creating a replay attack.BIP-110's peak miner support was approximately 2.53%. After the consensus rules took effect on August 8, the minority chain produced only two consecutive blocks before stalling, while the Bitcoin main chain continued operating and widening the block height gap. The BIP-110 proposal was subsequently marked as closed, and supporters shifted focus to discussing the BLAKE2b proof-of-work scheme.Bitcoin Knots plans to add a new signature hash option, but RDTS will still maintain compatibility with Bitcoin Core's existing signature hash types. Regular transactions may continue to be valid on both chains. Users will need to use the new option and rely on wallets or hardware signing firmware that support it to achieve asset separation.Luke Dashjr stated on August 18 that Bitcoin should bear the responsibility for replay protection, calling it "Spamcoin." If the BLAKE2b fork proceeds around September 1, exchanges, wallets, and holders will need to distinguish between cross-chain transactions and chain-specific transactions. (Bitcoin.com News)
Maya Protocol founder AaluxxMyth disclosed that the protocol was attacked, with approximately 20 BTC (around $1.4 million) and other assets (around $300,000) stolen. The team has suspended global operations to contain losses and is fixing vulnerabilities to restore trading. Most of the losses resulted from arbitrage and pool fees caused by extreme slippage. The team is communicating with relevant parties and plans to recoup the funds through methods such as investments in Aztec Chain. If the 20 BTC are returned to the pool, the CACAO token price will recover to $0.115. The team also hopes the attacker will accept the bug bounty and return the funds.
Odaily News: A bitcoin wallet created in 2012 has moved 212 BTC after remaining dormant for 14 years, valued at $13.72 million based on the price at the time of transfer. The wallet address was created on August 10, 2012. These bitcoins were originally worth $2,346, with a per-coin price of $11.07; at the article's quoted price of $64,761, if sold in full, the holder would realize a gain of 584,725%. The wallet owner's identity remains unknown. The 212 BTC has been transferred from a legacy P2PKH wallet to an unlabeled Bech32 wallet, arriving in multiple batches before being consolidated. A Coldcard vulnerability led to the theft of nearly 2,000 BTC, which may have prompted some long-term holders to move their assets, but this address has not been linked to any known entity.

Odaily News: Peer-to-peer cryptocurrency trading platform NoOnes announced that it will begin gradually winding down operations after running for over three years. The company stated that it had been continuously seeking to resolve and lift the sanctions imposed on NoOnes, but ultimately failed. The sanctions caused the platform to lose key partners, and blockchain monitoring firms also flagged transactions associated with NoOnes as high-risk, making it increasingly difficult for the platform to continue normal operations. According to the plan, the business contraction began on August 17, and the P2P marketplace will close at 23:59 UTC on August 21. Services such as Swap, NoOnes Visa, fiat withdrawals, the gift card store, and the Bitcoin Lightning Network will also be discontinued progressively. After that, the platform will only support withdrawals, and users will still be able to log in, view balances, and withdraw remaining assets. The company advises users to complete asset withdrawals as soon as possible, no later than August 23. Previously, on January 26, 2025, NoOnes revealed that the platform had suffered a major security breach earlier that month, resulting in losses of approximately $8 million in crypto assets. CEO Ray Youssef confirmed the news after on-chain detective ZachXBT disclosed the hacking incident on his Telegram channel.
Odaily News - Bitcoin News announced on the X platform that BitBox has disclosed two severe hardware wallet vulnerabilities, stating there is currently no evidence that these vulnerabilities have been exploited or led to user fund theft. All disclosed issues have been fixed in firmware v9.26.5, and BitBox urges all users to update immediately. An internal security audit uncovered two severe vulnerabilities, along with new details regarding a previously fixed bootloader vulnerability. One vulnerability affecting BitBox Multi devices could allow a malicious host to execute arbitrary code and install malicious firmware on devices that have not yet completed setup. Another vulnerability in Silent Payments could allow an attacker to exploit a malicious host device to redirect funds to unintended addresses, resulting in Bitcoin being locked and potentially enabling extortion attacks. BitBox also disclosed that the previously fixed bootloader vulnerability could allow attackers to trick users into installing malicious firmware capable of stealing funds.
