What to know:
- Trezor warned of phishing emails post July 31 exploit where 594 BTC was stolen.
- Scammers are impersonating Trezor/Ledger support to target anxious users.
- Hardware wallets cut exchange risk, but phishing remains the threat.
Trezor, the hardware wallet provider, has identified a noticeable increase in phishing email assaults targeting self-custody crypto investors coming after the July 31 COLDCARD exploit.
They are advised to ignore any unsolicited migration orders and refrain from sharing their private seed phrases since the scammers will probably exploit panic among users.
What Prompted The Alert
On the 31st of June, a malicious actor used a 5-year-old vulnerability in the key-generation of COLDCARD hardware wallets to steal 594 BTC, worth roughly $38M, out of about 500 self-custody wallets.
Although the thefts were fairly minor compared to the daily Bitcoin transaction amounts, Glassnode data reveals that Revived Supply 1y+ shot up to 119,423 BTC within 3 days after users moved assets.

Phishing Spree Follows Chain Events
Phishing attacks frequently occur following wallet-related incidents as attackers imitate support teams from Trezor, Ledger, and other companies to send emails and direct messages which ask for ” urgent migration ” or ” seed verification “.
Trezor’s alert is consistent with the industry recommendations which state that seed phrases should never be typed on the Web, and that firmware updates should be installed only via official channels. Self-custody users, institutions using multi-sig, and developers who make their own crypto retail-friendly tools are among those who are most at risk.
