Electrum Releases Version 4.8.2, Fixing Critical Backup Issue for Lightning Wallets and Strengthening Security

Odaily Reports: Bitcoin News posted on X platform that Electrum has released version 4.8.2, introducing multiple security fixes and strengthening the security of its Bitcoin wallet codebase. The fixes are based on reports from researchers including Bitcoin Red Team, Calle, l0rinc, haoxucu, and m0wer. This version fixes a critical backup issue affecting certain Lightning wallets that use non-deterministic keys and anchor channels. Previously, affected wallets' channel backups and full wallet backups may have been missing the keys required to move funds on-chain after requesting a remote force close. Affected users will receive a warning when starting Electrum and should export new backups, as old backups cannot correctly recover funds in this scenario. This version also strengthens Lightning HTLC verification, rejects previously accepted malformed xpub/xprv keys, expands codebase security hardening, and prevents the Android QR code scanner from reading screenshots. This is Electrum's third security-focused release since July, following versions 4.8.0 and 4.8.1.
