Hardware wallet manufacturers Trezor and BitBox warn users against phishing emails disguised as emergency security notices
Recently, well-known hardware wallet manufacturers Trezor and BitBox jointly issued a warning to users to remind the public to be wary of phishing emails disguised as emergency security notices. This risk stems from a suspected breach of third-party email services.
Trezor: Email provider leaked, urging users not to click on links
On Wednesday, Trezor officially announced that its email service provider had been breached and clearly stated that the message titled "Critical Security Alert: STM32 Entropy Vulnerability" was forged. The company urges recipients not to click on any links in the email.
BitBox: The newsletter provider may be damaged, and many Bitcoin companies may be implicated.
On the same day, BitBox also issued a warning about phishing emails. The company said preliminary review showed that its news communication provider may have been compromised, adding that multiple bitcoin-related companies appeared to have been targeted through shared service providers.
Recent industry security incidents have occurred frequently
