Scammers target hundreds of thousands of crypto owners after Trezor confirms data breach of email provider

Filed by Ada Circuit

Trezor, the hardware crypto wallet maker, has confirmed a data breach at its email provider, exposing customer data to scammers who are now targeting hundreds of thousands of crypto owners with phishing attacks. This marks the second time a third-party vendor's compromise has impacted Trezor's users, raising serious questions about the security of the broader ecosystem around self-custody crypto hardware. While the hardware wallets themselves were not directly compromised, the breach of a peripheral service—email delivery—has proven to be a critical attack surface. The incident underscores that even the most secure devices can be undermined by weaknesses in the surrounding infrastructure, and it highlights the growing sophistication of phishing campaigns aimed at draining crypto holdings.
