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.
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.
