Crypto hardware wallet provider Trezor has launched an investigation into a possible data breach that may have compromised users’ email addresses and other personal information.

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

In the ongoing attack, several Trezor users have been contacted by unauthorized persons claiming to be the company with the ultimate goal of stealing funds by misleading negligent investors. As part of the attack, users received an email to download an app from the “trezor.us” domain, which is different from Trezor’s official domain name, “trezor.io”.

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

During a further investigation, Tresor declared:

“MailChimp has confirmed that their service has been hacked by an insider targeting crypto companies.”
While Trezor is conducting an official investigation to determine the total number of stolen email addresses, users are advised not to click on links from unofficial sources until further notice.
