Ledger users receive scam letters disguised as official requests for their mnemonic phrase.

Foresight News reported that cryptocurrency trader Jacob Canfield tweeted that recently users of the hardware wallet Ledger received paper letters disguised as official Ledger correspondence, requesting them to scan a QR code and provide their wallet mnemonic phrase to execute a "critical security update," or risk having their wallet access restricted. Ledger's official response stated that this is a scam and reminded users to remain vigilant, as Ledger will never ask for a phone call, message, or mnemonic phrase. This incident may be related to the data breach of Ledger in July 2020, when personal information of over 270,000 users was leaked.
