A recent rise in phishing scams has alarmed crypto enthusiasts as reports surface about deceptive letters featuring malicious QR codes. One letter claimed to be from Trezor, highlighting the growing sophistication of these attacks.

The Shift to Physical Phishing

Scammers are now moving from digital to physical correspondence. People have voiced their disbelief on forums. One commenter noted, "When you think about it, this is so ridiculous to send someone with crypto a physical mail."

The QR code in the letter led to a phishing site, identified as trezor.hardware-update.io. With mounting concern, people have been urged to report this site to Google Safe Browsing, as community action can quicken the blacklisting process. "The more people report it, the faster Google can blacklist it," mentioned a prominent figure in the forums.

Interestingly, commenters shared fears about how scammers obtain personal information. One asked, "Did Trezor have a data leak? How do these scammers have your information?" This fear highlights a significant concern over privacy and data security.

User Reactions and Notable Observations

As many expressed skepticism towards any crypto-related mailings, one stated, "Quite literally, it’s long been known that anything crypto-related sent through the mail is a scam."

Responses indicate a sense of urgency regarding QR code safety. Some users are pondering how to safely check QR codes without risking exposure. One user shared, "I scanned it with my travel phone I use in case it gets nothing ever connected to it."

Meanwhile, others openly criticized those who fall for such scams, saying, "If you fall for that you have no business whatsoever holding custody of your own funds!"
