Trezor says hackers compromised its email service provider

Trezor reported that hackers breached its email provider, raising risks of phishing and social-engineering attacks targeting hardware wallet users. While the incident is not a direct protocol-level issue, it can undermine confidence in self-custody workflows and increase near-term operational risk across the crypto ecosystem. Markets often treat security and trust shocks as a headwind for risk appetite, particularly for BTC-linked flows.
