Ledger has warned that scammers are mailing letters that appear to be from the company to users of its hardware wallets in an attempt to swipe crypto.

Scammers are mailing physical letters to the owners of Ledger crypto hardware wallets asking them to validate their private seed phrases in a bid to access the wallets to clean them out.

In an April 29 X post, tech commentator Jacob Canfield shared a scam letter sent to his home via post that appeared to be from Ledger claiming he needed to immediately perform a “critical security update” on his device.

The letter, which uses Ledger’s logo, business address, and a reference number to feign legitimacy, asks to scan a QR code and enter the wallet’s private recovery phrase under the guise of validating the device.
