The Liquid Network is a Bitcoin layer-2 solution that enables fast, confidential settlement and issuance of digital assets, such as stablecoins, security tokens, and other financial instruments, on top of the Bitcoin blockchain.
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 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.
Odaily News: Canadian Bitcoin exchange and wallet company Bull Bitcoin stated that due to the Liquid Network attack on September 6, users are temporarily unable to redeem L-BTC back to Bitcoin through the platform, and redemption operations are still pending resumption.Bull Bitcoin expects the related redemption service to potentially resume within 30 days, but stated that this expectation is not guaranteed. Due to its reliance on the L-BTC redemption mechanism to balance inventory, the platform has temporarily closed inbound Lightning Network payments.In this attack, the attacker transferred out nearly 4,000 Bitcoin from the protocol, later returning approximately 3,400; currently still holding 598.50 Bitcoin, valued at over $51 million. Liquid Network stated on September 17 that block production, network transactions, and L-BTC transfers have returned to normal. (Bitcoin.com News)
SlowMist has disclosed that the Liquid Network was attacked on September 6 via a Rangeproof verification cache key collision vulnerability. The attacker minted approximately 3,998.5 L-BTC without collateral — with no corresponding BTC peg-in — and then within minutes converted them to BTC on the Bitcoin mainnet via peg-out. After the incident, approximately 3,400 BTC was returned to the Liquid Federation peg wallet, but approximately 598.5 BTC remains under the attacker's control.SlowMist noted that the root cause of the vulnerability lies in the fact that the Rangeproof verification cache key in Elements did not include length prefixes when concatenating multiple variable-length fields, allowing different parameter combinations to potentially generate the same cache key. The attacker triggered a cache collision by constructing transactions, causing nodes to hit a "verification passed" cached result, thereby bypassing secp256k1_rangeproof_verify and the minimum amount check, ultimately accepting outputs not backed by real assets and completing the L-BTC minting. SlowMist stated that it has traced the fund flows on the Bitcoin side and completed its analysis of the incident.
According to on-chain monitoring by analyst PeckShield (@PeckShieldAlert), the Liquid Network was targeted by white-hat hackers. Approximately 4,000 BTC (roughly $320 million) were transferred from a Liquid Federation wallet. The funds were consolidated into address bc1ql4mfu6aundtkksxklfajs2h3t9nzcd6gyqjlte, accompanied by an on-chain message: "We are white hats, please contact us on-chain." Subsequently, the hackers completed on-chain negotiations with Blockstream, returning 3,400 BTC (approximately $315 million, or 85% of the total) while retaining around 598.5 BTC (about $47.38 million) as a bug bounty.
Odaily News — Multiple Bitcoin ventures associated with Bitcoin pioneer and Blockstream co-founder Adam Back have recently suffered a series of setbacks: the merger between BSTR Holdings, the Bitcoin treasury project he championed, and a SPAC under Cantor Fitzgerald has been terminated, with BSTR ordered to pay a $15 million breakup fee; Blockstream Mining, the Bitcoin mining operation he co-founded and in which he holds a minority stake, along with its partner Exacore, has faced multiple lawsuits following its spin-off from Blockstream, accused of owing equipment payments, electricity bills, and customer deposits, with related financing totaling approximately $2 billion; meanwhile, Liquid Network, the Bitcoin sidechain initiated by Blockstream, suffered a hack in which approximately 4,000 BTC were stolen, of which 3,400 have been returned, with the hacker still retaining approximately $47 million worth of Bitcoin.

Odaily News: According to Bitcoin News monitoring, its latest newsletter reviewed multiple security incidents over the past eight weeks involving projects that Bitcoin users rely on in their daily activities, with a focus on the latest major exploit targeting Liquid Network.
Odaily News: On-chain security platform Blockaid has discovered a vulnerability in the Bitcoin bridge of cross-chain protocol Symbiosis. The attacker minted approximately 2^62 syBTC to a newly created externally owned account, with a face value of roughly $46.1 billion calculated at 8 decimal places, and sold approximately 4.39 WBTC on Uniswap V4 on Ethereum, realizing a cash-out of about $336,000.Symbiosis stated that the attack occurred at around 4:28 AM on September 11. The team has paused the BTC route, while other routes remain operational and unaffected. The team has recovered approximately 15 BTC and deposited them into a multisig wallet controlled by the team. They have also offered the attacker a 20% white-hat bounty, with a deadline of September 13.In recent weeks, Liquid Network, Nomic, and Symbiosis have all experienced security incidents involving the inflation of supply through the minting of tokens without real asset backing. As of September 13, Symbiosis has not yet publicly released a BridgeV2 technical post-mortem, the final loss amount, or confirmation of whether the attacker has accepted the bounty.

Bitcoin News posted on X stating that Samson Mow and Bitcoin Red Team researcher Calle are engaged in a public dispute over whether security warnings related to a Liquid Network exploit were properly handled. Calle claims that Blockstream did not act on the Red Team's email, ultimately resulting in a loss of 600 BTC; Mow responded by saying "no email was ignored." Calle stated that once Blockstream restores normal Liquid operations and publishes a post-mortem report, the Red Team will release a full account of the disclosure process. Mow separately warned against blindly trusting AI-generated security reports, saying that unverified fixes could introduce new vulnerabilities, and criticized researchers who prioritize pursuing "clout" over protecting Bitcoin.
