Trezor investigates potential data breach as users cite phishing attacks

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

early 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.

Hello trezor, are you aware of a phishing campaign? I just received this email with my real email. It seemed very legit.

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 ‘’, which is different from Trezor’s official domain name ‘’.

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, 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 @Trezor, this is the best phishing attempt I’ve seen in years. I’m really lucky I don’t have Trezor, because if I did, I’d probably download that update.

Through further investigation, Trezor announced:

While Trezor is officially investigating to identify the full number of stolen email addresses, users are advised not to click on links from unofficial sources until further notice.

On March 19, New Jersey-based crypto-financial institution BlockFi proactively confirmed a data breach to warn investors about the possibility of phishing attacks.

As Cointelegraph reported, the hackers gained access to BlockFi customer data that was hosted on Hubspot, a customer relationship management platform. According to BlockFi:

“Hubspot has confirmed that an unauthorized third party gained access to certain BlockFi customer data hosted on its platform.”
