【A “spy board” hidden in a hardware wallet! Trezor confirms 3 Safe 5 devices were tampered with and cuts 80% of its resellers】
On November 12, Trezor confirmed that three Safe 5 devices purchased from former Southeast Asian reseller CryptoBilis between August 20 and September 23 had been fitted with an extra circuit board. Sandwiched between the motherboard and screen, it recorded the recovery phrases displayed and entered on the screen, then secretly sent them to attackers over a mobile network. Firmware version 2.13.1, released on November 11, can disable the implanted boards, but recovery phrases stolen before the update cannot be recovered. CryptoBilis customers still need to create new recovery phrases and transfer their assets. No users have reported losing funds so far, and Trezor has cut about 80% of its resellers.
