Over 50 BTC Rescued from COLDCARD Entropy Vulnerability Wallets, Funds Transferred to Crypto Recovery Trust Pending Return

Odaily News: According to Bitcoin News monitoring, DART stated that it and independent white-hat researchers have recovered over 50 BTC from wallets affected by the COLDCARD entropy vulnerability, completing the transfer before malicious attackers could steal the funds. DART is a digital asset recovery organization that works with white-hat researchers to protect vulnerable funds and coordinate their lawful return to owners. The white-hat researchers did not request a bounty and will return the Bitcoin to its owners.The rescued BTC has been transferred to the Crypto Recovery Trust. This trust is a dedicated statutory trust established under Wyoming state law to hold recovered digital assets and return them after confirming and verifying the legitimate owners. The trust will document the recovery process, separate the BTC from DART and researchers' funds, conduct blockchain analysis, ownership verification, and sanctions screening, and provide a lawful return process for verified owners. If ownership is disputed, or if the relevant funds involve sanctions or criminal proceedings, the BTC will be handled in accordance with applicable legal procedures. DART stated that other vulnerable assets and recovery leads are still under review.

Liquid Network Releases Emergency Fix: Elements v23.3.4 Patches Proof Validation Cache Vulnerability

Odaily News: Liquid Network announced that the emergency release Elements v23.3.4 is now live, with Functionary nodes having immediately begun upgrades. All Liquid node operators are advised to update accordingly. This release addresses a previously identified Proof validation cache vulnerability by strengthening the cache keys used for Range Proofs.Regarding network recovery, Blockstream stated that a recovery plan is still being formulated, expected to proceed in three phases: **resume block production while continuing to pause Peg operations; replay verified valid transactions; restore Peg operations after the network state is fully recovered and fund returns are confirmed.** Currently, the first two phases are being tested in parallel, and any phase will only advance once confirmed secure.Liquid Network stated that Elements v23.3.4 has undergone multiple rounds of internal and external reviews, with participants including the Bitcoin Red Team, Alpen Labs, and other teams. Meanwhile, Liquid Network reminds users to be wary of fake upgrade websites exploiting this incident for scams. Information should only be obtained through official Liquid Network and Blockstream channels, and users should never send funds to strangers or disclose private keys or seed phrases.

Liquid white hat hacker group demands Blockstream pay 10% bug bounty for $5 billion in assets

According to Odaily Planet Daily, as monitored by Bitcoin News, the white hat hacker group behind the Liquid exploit has accused Blockstream of spending only $1.5 million—or possibly nothing at all—to secure $5 billion in assets. In a new on-chain message, the group demanded that Blockstream allocate its own funds to pay a bug bounty equivalent to 10% of the associated assets, warning that refusal to pay would result in a 15% loss for holders. The group also stated it would release the private keys used to decrypt previous communications with Blockstream. Earlier, the group had returned 3,400 BTC to the Liquid Federation, with approximately 600 BTC still unrepaid.

Alby Hub old versions have critical vulnerability, publicly exposed management API could lead to fund transfer

Bitcoin News posted on X platform that Alby has confirmed a critical vulnerability in Alby Hub v1.7.0 through v1.18.5. If the management API is exposed to the public internet, attackers could gain unauthorized access and transfer funds. Currently, 1 user is known to be affected, and Alby Hub v1.19.0 and later versions are not affected. Alby recommends affected users restrict public access to the management interface, update to v1.24.0 immediately, and change their unlock password after updating. Multiple issues reported by Bitcoin Team Red, Project Loupe, and other researchers have also been fixed in the latest version.

Liquid Network: In discussions with white hat to recover remaining 598.5 BTC, network restoration efforts also underway

Liquid Network's official security incident report: On September 6, a vulnerability related to the range proof verification method in Liquid node caching within the open-source software Elements was exploited, resulting in the creation of approximately 4,000 LBTC tokens not backed by bitcoin reserves. The exploiter subsequently exchanged them for approximately 4,000 BTC via SideSwap and the Liquid standard Peg-out mechanism. Prior to the incident, Liquid's reserves stood at approximately 4,205 BTC. After the relevant Peg-out and other withdrawals completed before the network halt, reserves fell to 197 BTC.According to the official statement, the incident did not involve the compromise of Functionary nodes or private keys, and other issued assets on Liquid such as USDT were also unaffected by the vulnerability. The exploiter claimed to be a white hat security researcher and returned 3,400 BTC to the Liquid Federation Peg wallet on September 7. Approximately 598.5 BTC (about 15% of the funds involved) remain unrecovered, and Blockstream is in communication to recover the remaining assets.At present, the top priority is to recover the remaining funds and restore Liquid Network to normal operation as quickly and safely as possible. A fix for the vulnerability has been developed and is currently undergoing multiple rounds of internal and external review. Blockstream is preparing to urgently release Elements v23.3.4, which is expected to be rolled out as soon as preparations are complete, with a target launch within approximately 48 hours. Following the software update, Liquid Network Functionary operators will make further adjustments to restore full network functionality and resume a corrected network state, including rejecting previously invalid Peg-outs.

Coldcard thief prioritizes emptying third wave of vaults, has moved 97.09 BTC worth approximately $7.7 million

according to Bitcoin News monitoring, the Coldcard thief is prioritizing emptying the largest portion of the third wave of vaults. Galaxy Research stated that these wallets have transferred out 97.09 BTC, worth approximately $7.7 million, accounting for about 45% of the assets in this batch. The attacker created 293 2/2 vaults themselves and previously moved some tokens via THORChain on September 2, followed by multiple rounds of CoinJoin over the weekend. The vulnerability stems from a 2021 firmware flaw that reduced seed entropy to a minimum of 40 bits. Of the tokens stolen in this exploit, approximately 82% remain unmoved.

Four people killed in Mexico, suspects accused of stealing a cold wallet holding millions of dollars in Bitcoin

Odaily News: The State Attorney General's Office of Mexico (FGJEM) stated that two suspects are accused of killing four people in search of a cold wallet believed to contain millions of dollars in Bitcoin. The two are scheduled to appear in court on Wednesday, where a judge will determine whether there is sufficient evidence to continue criminal proceedings.The surnames of suspects Diego Sebastián and Gerardo have not been disclosed. Prosecutors allege that the pair killed Jonathan Meléndez, keyboardist for the rock band Camilo Séptimo, his pregnant wife, their daughter, and an employee at a residence in the city of Atizapán de Zaragoza.

U.S. Department of Justice Prosecutes Group in $240 Million Bitcoin Theft Case, Ringleader Expected to Plead Guilty

According to the Associated Press, the U.S. Department of Justice has charged Ma Long Ram and 17 other defendants in connection with a Bitcoin theft scheme valued at over $240 million. Prosecutors allege that the group carried out a social engineering attack on a Washington resident by impersonating employees of Google and cryptocurrency exchange Gemini, thereby gaining control of their accounts and security codes to steal more than 4,100 Bitcoin. The suspects subsequently laundered the proceeds through multiple trading platforms and spent the money on sports cars, mansions, luxury watches, private jet services, and nightclub expenses.

Blockstream notifies white hat hackers that vulnerability has been fixed, approximately 4,000 BTC pending return

Odaily News: Blockstream has notified white hat hackers that the vulnerability fix is complete and the approximately 4,000 BTC can be safely returned. The hacker who previously withdrew funds from the Liquid network expressed willingness to return them, but requested that the vulnerability be fixed first. Both parties have been negotiating publicly through Bitcoin OP_RETURN messages.The hacker initially proposed returning "most" of the BTC, but later changed their stance, demanding that the vulnerability be fixed first: "Ensure every node has been patched, and once the fix is confirmed, we will securely return the funds." The hacker also sent encrypted vulnerability details to Blockstream. About two hours ago, Blockstream responded via a PGP-signed OP_RETURN message stating that nodes have been patched. Currently, 3,998.5 BTC remain under the hacker's control.

Coldcard Wave 3 Attacker Has Transferred Approximately 45% of Stolen Bitcoin

According to Galaxy Research, in the Coldcard wallet attack incident, the Wave 3 attacker has transferred approximately 45% of the stolen Bitcoin, with the related funds routed to Ethereum via THORChain or entering CoinJoin transactions to increase tracking difficulty. Galaxy stated that the attacker previously created 293 2-of-2 multisig vaults to hold victim funds, draining them from largest to smallest amount, and the funds in the 11 largest vaults have now been fully transferred out.

Vitalik refutes Silicon Valley investor's "AI will kill BTC" argument: The probability of hash algorithms or PoW being broken is extremely slim

Odaily News Silicon Valley angel investor Liron Shapira (@liron) posted on X this morning: "I predict (with 50% confidence): due to AI shaking the security and stability guarantees people once believed Bitcoin possessed, BTC's price will plummet more than 50% within the next two years."Ethereum co-founder Vitalik Buterin rebutted this, stating: "I hold the exact opposite view. My basic reasoning is that, in the long run, I am quite optimistic about network security. I believe the main challenge lies in smoothly navigating the transition period. Moreover, I think BTC can at least properly handle all problems that do not require social consensus (such as upgrading clients, mining pools, etc., to counter network-level attacks — these fall into this category). Additionally, I believe the probability of hash algorithms or proof-of-work mechanisms being genuinely broken is extremely slim. I would have wanted to bet with you, but considering my current asset allocation (I guess you hold the same view regarding Ethereum ETH), I have already staked about 90% of my net worth on this bet."

After fixing the vulnerability, Liquid's white hat hacker said they would return most of the 4,000 BTC

According to Odaily, monitoring by Galaxy's Head of Research revealed that Liquid's white hat hacker stated they would return most of the 4,000 BTC after the Liquid Network vulnerability is patched. The hacker communicated with Blockstream through OP_RETURN messages and PGP-encrypted text: In block 965,822, a Blockstream address sent 1,000 satoshis with the message "Please contact the security team via the Blockstream website"; in block 965,865, the hacker sent an encrypted message to their own key, accompanied by a detached PGP signature that can be verified using the key published by Blockstream; in block 965,869, the hacker sent 1,000 satoshis to the Liquid federation peg-in wallet via a self-spend transaction with the message "Can we return the majority of the funds to the federation address?"; in block 965,875, the hacker conducted another self-spend transaction, sending 1,000 satoshis to the federation peg-in wallet and leaving an OP_RETURN message: "Please fix the vulnerability first. As of the latest commit, there is risk on-chain. Please ensure every node completes the patch update. Once the fix is confirmed, we will securely transfer the funds back." Relevant technical details were encrypted via PGP messages to the key published by Blockstream, readable only by Blockstream.

Approximately 45% of stolen assets have entered coin mixing or cross-chain paths, Coldcard attacker continues to move funds

Odaily News: The attacker behind the Coldcard "Wave 3" exploit continues to move stolen funds. In this phase, the attacker created 293 separate 2-of-2 multisig vaults for each victim's assets. On September 2, the first batch of funds was bridged to Ethereum via THORChain; the latest round of transfers has begun entering the CoinJoin mixing process.Currently, the Wave 3 attacker is processing the largest holdings in descending order by stolen amount, having already transferred vaults ranked 1 through 11 in sequence. The next 10 vaults yet to be transferred collectively hold 30.81 BTC, while vaults ranked 61 through 293 collectively hold 33.77 BTC.To date, the attacker has moved approximately 45% of the assets stolen in this exploit, with funds either flowing to Ethereum or entering CoinJoin mixing transactions. This latest transfer activity has also revealed a previously unknown vault: 58 addresses jointly spent funds via a 2-of-2 multisig setup in the same format as Wave 3, with the Wave 3 attacker subsequently routing them to a jump address that funds CoinJoin transactions.This vault is currently marked with "cause = open," but it is highly likely to belong to Coldcard victims as well, which could bring the total number of vaults involved in Wave 3 to 294 and push the previously disclosed total stolen in the Coldcard exploit to approximately 1,806 BTC. At present, roughly 82% of the stolen BTC remains in addresses initially controlled by the attacker, while approximately 18% has been moved, with fund flows suggesting it may be undergoing laundering.

White-Hat Hacker Withdraws Approximately 4,000 BTC from Liquid Network; Side Chain Suspends Operations

According to an announcement from the official Liquid Network X account (@Liquid_BTC), a suspected whitehat hacker withdrew approximately 4,000 BTC worth around $320 million from a Liquid Federation wallet using a SideSwap PAK (Peg-out Authorization Key). The official statement indicated that the key itself was not leaked, and the Blockstream team is attempting to contact the party through on-chain signed messages. Following the incident, exchanges have paused or are about to pause LBTC deposit and withdrawal services. Bridge nodes have been temporarily shut down, and the Liquid sidechain is currently suspended, unable to submit new transactions. Officials emphasized that other Liquid assets such as USDT, DePix, and RWA remain unaffected by this incident, while Federation members are actively working to resolve the issue to restore normal network operations as soon as possible.

Approximately 4,000 BTC transferred in a single transaction linked to Liquid Network, with an on-chain message calling it a "white hat" operation

Odaily News: According to Bitcoin News monitoring, out of 4,200 BTC associated with a peg-out transaction on the Liquid Network, approximately 4,000 BTC appear to have been moved simultaneously. A subsequent transaction included an OP_RETURN message stating: "We are white hats, please contact us on-chain." It remains unclear what the nature of this transaction is, and whether the funds were moved through an exploit.

Bitcoin fork asset BTCB2 once hit $1,799, with a fully diluted valuation of $20.9 billion calculated at a price of $1,000

Odaily News: Bitcoin fork asset BTCB2 hit an all-time high of $1,799 on September 5. Over the past 4 hours, its price has fluctuated between 750 and 1,000 USDC; the Neoxa USDC market recorded a 24-hour trading volume of approximately $1 million.BTCB2 originated from a chain split that occurred on August 8, 2026, at block height 961,632. The network subsequently changed its proof-of-work algorithm to Blake2 and reduced block size, and it can now be mined using Blake2-compatible ASIC miners.Neoxa Exchange and Nonkyc.io have listed BTCB2, with the former offering BTC, USDC, and USDT trading pairs, and the latter offering a USDT trading pair. Both platforms have limited liquidity, and CoinMarketCap and CoinGecko have not yet listed the asset.Based on a BTCB2 price of $1,000, its fully diluted valuation stands at approximately $20.9 billion. Since UTXOs need to be split from Bitcoin first, transactions may otherwise be vulnerable to replay attacks; the network's hash rate has risen by 30.41% over the past 7 days, reaching approximately 5.1 PH/s.

G7 urges immediate migration to post-quantum cryptography; Bitcoin, Ethereum, and Solana developers have tested defense solutions

: The G7 cybersecurity working group stated in its latest report that quantum computing poses both a security threat and an economic threat to public and private institutions, and related organizations should immediately begin migrating to post-quantum cryptography (PQC).The working group noted that the migration process could take several years, as attackers can already collect and store encrypted data today and decrypt it once sufficiently powerful quantum computers emerge. Quantum computing could also break digital signatures, leading to identity theft and exposing companies and their supply chains.The report did not mention cryptocurrencies, but similar public-key cryptography is used for blockchain wallets and transaction authorization. Current quantum computers are not yet capable of breaking Bitcoin's cryptography, but developers are considering post-quantum solutions such as BIP-360.Ethereum researchers plan to replace multiple cryptographic components used by accounts, validators, and applications. The Solana Foundation has tested post-quantum signatures on its testnet and launched an optional hash-based vault. The G7 working group also urged governments to support related research, public-private cooperation, and national PQC strategies. (Decrypt)
