Industry exec sounds alarm on Ledger phishing letter delivered by USPS
Scammers are sending fraudulent letters to crypto users, impersonating Ledger, and instructing them to "validate" their wallets to avoid losing access to funds. The letters include a QR code linked to a phishing site and were sent via USPS. Experts warn that these scams aim to steal crypto private keys and sensitive data. In April 2025, a phishing attack resulted in the theft of $330 million in Bitcoin from an elderly victim, with suspects identified as operating a call scam center. Coinbase faced a ransom attempt after customer service contractors leaked user data, demanding $20 million, which the company refused to pay. No private keys or login credentials were compromised in the leak, but criticism arose regarding the security failure and potential risks to affected customers.
