[Scammers Impersonate Ledger to Send Physical Letters, Attempting to Steal Users' Mnemonic Phrases] According to a report by Jinse Finance and Cointelegraph, scammers are sending physical letters to users of Ledger hardware wallets, impersonating the Ledger company and requesting users to provide their private mnemonic phrases in an attempt to gain control of their wallets. These letters use Ledger's logo, company address, and reference numbers to disguise their authenticity, claiming that users need to immediately perform a 'critical security update.' The official Ledger team has confirmed that this is a scam and reminds users that they will never request mnemonic phrases in any way.
