Trezor investigates potential data breaches as users cite phishing attacks

Cryptocurrency hardware wallet provider Trezor has begun investigating a possible data breach that may have compromised users’ email addresses and other personal information.

Today, April 3rd, several users from the Crypto Twitter community warned about an ongoing email phishing campaign specifically targeting Trezor users via their registered email addresses.

In the ongoing attack, several Trezor users were contacted by unauthorized actors posing as the company with the ultimate intention of stealing funds by misleading unwary investors. As part of the attack, users received an email about downloading an app from the domain “”, which is different from the official Trezor domain name “”.

Trezor initially suspected that the compromised email addresses belonged to a list of users who had signed up for newsletters hosted by an American email marketing service provider, Mailchimp.

While Trezor is attempting to identify the cause of the situation with an official investigation, users are advised to refrain from clicking on links originating from unofficial sources until further notice.
