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

“The recent data breach at Brevo, a marketing platform used by Trezor, exposed the personal information of roughly 347,000 crypto wallet users, enabling attackers to send targeted phishing emails that trick recipients into downloading malicious software requesting their wallet backup passwords. In the U.S., where crypto ownership is growing and regulatory oversight is tightening, this incident underscores the vulnerability of third‑party services that handle customer data and the potential for significant financial loss and reputational damage to wallet providers. The breach also raises concerns about physical “wrench” attacks, as attackers may use stolen addresses to target wealthy crypto holders with fake mailers. Expert Analysis: This event highlights the need for stricter vendor risk assessments and end‑to‑end encryption in the crypto ecosystem. If wallet companies adopt zero‑trust models for third‑party integrations, they could reduce the likelihood of mass phishing campaigns and protect consumer assets more effectively.”
