@Liquid_BTC: white-hat hackers withdrew 4,000 BTC from Liquid Federation wallet

Liquid Federation's sidechain has been paused after purported white-hat hackers withdrew about 4,000 BTC (about $320 million) from its wallet. The incident is linked to the SideSwap PAK (Peg-out Authorization Key), which the article says was used for the withdrawal but was not compromised, nor were any other keys. Exchanges have paused or will pause LBTC deposits and withdrawals, and bridge nodes have been temporarily disabled, so no new transactions can be submitted. Blockstream is working to contact the hackers on-chain with a signed message, and Federation members are working to restore normal network activity.
