A user's hardware wallet has not been used for a long time, resulting in a swollen battery. After replacing the battery, it was found that the wallet had been initialized
ChainCatcher message, Slow Mist Yu Xian forwarded a security case about hardware wallet usage on platform X: "A user stored BTC in a hardware wallet thinking it was safe, but after a few years, when they took it out, they found the battery had swollen and it was unusable. They found the same model wallet and went to Huaqiangbei to replace the battery, only to discover that the wallet had been initialized and there was no backup, resulting in a permanent loss. This serves as a reminder that if you use a hardware wallet, you must also ensure proper backups. If you need to repair a hardware wallet, make sure to find a professional hardware team."Yu Xian commented on this: "After a few years, the battery has swollen and the wallet has been initialized? Which hardware wallet is this? We need to avoid it... If there is a mnemonic backup, it can be tolerated... But without a backup, it's really..."
