NEW: Ledger is phasing out the Ledger Nano S, the best-selling crypto hardware wallet in history. They caution that ongoing support for the Nano S is not guaranteed and are urging users to upgrade, requiring them to re-enter their seed phrase into a new device. This process exposes users to phishing risks. A Ledger data leak has already led to a surge in targeted scams, including fake but official-looking letters sent by mail, prompting users to enter their seed phrase into fraudulent devices.
