Trezor investigates possible data breaches as users cite phishing attacks

Trezor, a provider of cryptocurrency hardware wallets, has begun investigating a possible data breach that could have affected users’ email addresses and other personal information.

Earlier today, on April 3, several users of the Crypto Twitter community warned of an ongoing email phishing campaign targeting Trezor users through their registered email addresses.

In the ongoing attack, several Trezor users have been approached by unauthorized actors posing as the company – with the ultimate intent to steal money by deceiving 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 signed up for newsletters, which was hosted on a US email marketing service provider Mailchimp.

Although Trezor is trying to determine the cause of the situation with an official investigation, users are advised not to click on links from unofficial sources until further notice.

“Hubspot has confirmed that an unauthorized third party has gained access to certain BlockFi client data residing on their platform.”

While details of the breached data have yet to be identified and disclosed, BlockFi reassured users by emphasizing that personal data — including passwords, government-issued IDs, and Social Security numbers — “is never stored on Hubspot.”
