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

Earlier today, on Apr. 3, several users from the Crypto Twitter community warned about an ongoing email phishing campaign specifically targeting Trezor users via their registered email addresses.

Hey trezor, are you aware of a phishing campaign going on? I just received this email with my actual email on it. It looked 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 to steal funds by misleading unwary investors. As part of the attack, users received an email about downloading an app from the ‘trezor.us’ domain, which is different from the official Trezor domain name, ‘trezor.io.’

We are investigating a potential data breach of an opt-in newsletter hosted on MailChimp.A scam email warning of a data breach is circulating. Do not open any email originating from [email protected], it is a phishing domain.

Trezor initially suspected that the compromised email addresses belong to a list of users who opted-in for newsletters, which was hosted on an American email marketing service provider Mailchimp.

Wow, @Trezor, this is the best phishing attempt I have seen in the last few years. I am really lucky I don't have Trezor, because if I had, I would probably actually 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 coming from unofficial sources until further notice.
