Summary

Since at least April 2025, scammers have mailed physical letters impersonating Ledger and Trezor to owners of those companies' hardware wallets, using holographic seals, forged executive signatures, and recipients' real names and addresses to demand a fake 'security check' via QR code. The QR codes lead to phishing sites that request the victim's 12-, 20-, or 24-word recovery phrase, which is then used to drain the victim's wallet. The campaign resurfaced in waves through 2025 and 2026, most visibly in February 2026 and again in March 2026, and both companies maintain they will never request a recovery phrase through any channel, including postal mail. This entry covers the mail-based phishing campaign itself and is separate from the main Ledger company page.
