Update on the Mailchimp data breach and what happened with your data


Details of the Mailchimp data breach This email contains details of a data breach which compromised our mailing provider between February and April 2, 2022. The attack saw Mailchimp employees being phished for privileged access to customer accounts, resulting in the theft of email addresses and in some cases names of subscribers and other data. Below you will find specific data belonging to you which was stolen in the attack. Data stolen in the attack

  • Your email address

  • Your IP address

  • An approximate location based on your internet provider

Please use this information to protect yourself and be wary of any incoming mail, as the targeted data is being used to send phishing emails to your inbox. Avoid clicking on any links in emails, and never ever enter your seed into a computer without your Trezor device telling you to do so. This is the latest information we have, following a week of investigation and reluctant cooperation from Mailchimp's senior security staff. You will find a timeline of events on Trezor blog, but we will not be providing any links here so this message does not get confused for a phishing attempt. For inquiries, please contact our security team at You will not receive any more emails from Trezor via Mailchimp. Given the broad scope of the attack, it is important that you remain on alert for phishing attacks coming from other sources, as hundreds of other brands and projects which have not yet been disclosed were also targeted.
