[Electrum Releases 4.8.2 Security Update, Fixes Lightning Wallet Backup Issues] Deep Tide TechFlow reports that on September 13, Bitcoin wallet Electrum released version 4.8.2, addressing multiple security issues and further strengthening the codebase's protection. This update resolves backup issues for certain Lightning wallets using non-deterministic keys and Anchor Channels. Existing channels or full wallet backups of affected wallets may lack the keys required to retrieve on-chain funds after remote force closure. Electrum will issue warnings to affected users upon startup and recommend re-exporting backups, as old backups cannot fully recover funds in such cases. Additionally, version 4.8.2 enhances Lightning HTLC validation, rejecting abnormal xpub/xprv keys that might have been accepted previously, and introduces screenshot protection for the QR scanner on Android.
