Cryptocurrency hardware wallet provider Trezor has begun investigating a potential data breach that may have compromised users' email addresses and other personal information.
Earlier today, on April 3, several users in the Crypto Twitter community warned of an ongoing email phishing campaign specifically targeting Trezor users via their registered email addresses.
Hi trezor, are you aware of a phishing campaign? I just received this email with my real email. It seemed very legit. pic.twitter.com/GF0Od6llr2

In the ongoing attack, several Trezor users have been contacted by unauthorized actors posing as the company, with the ultimate intention of stealing funds by tricking unsuspecting investors. As part of the attack, users received an email about downloading an app from the domain 'trezor.us', which is different from Trezor's official domain name 'trezor.io'.
We are investigating a possible data breach of a newsletter subscription hosted by MailChimp.
An email scam is circulating that warns of a data breach. Do not open any email originating from noreply@trezor.us, it is a phishing domain.

Trezor initially suspected that the compromised email addresses belonged to a list of users who opted in to receive newsletters, which was hosted by a US email marketing service provider, Mailchimp.
Wow, @Safe, this is the best phishing attempt I've seen in recent years. I'm really lucky I don't have Trezor, because if I did, I'd probably download that update. pic.twitter.com/DaBN2Oix11

While Trezor attempts to identify the root cause of the situation with an official investigation, users are advised not to click on links from unofficial sources until further notice.
