Trezor Investigation Update: Malicious Circuit Boards Found in Three Safe 5 Wallets Hardware Wallet manufacturer Trezor has provided an update on its investigation into the hardware of mixed devices sold by bestsellers CryptoBilis. After testing devices from 48 users who contacted the company, Trezor confirmed that three 5-cartsor secure wallets sold between August 20 and September 23, 2026, via CryptoBilis and Tokopedia and Shopee contained malicious circuit boards. The implants, hidden between the motherboard and the display, can capture recovery seeds and pass phrases displayed on the screen and transmit them to the attackers' servers via cellular networks. No user funds have been reported stolen to date. Trezor reduced its reseller network by about 80%, reduced controls and warehousing control, and released firmware version 2.13.1 on November 11 to block data by detected implants. Customers who purchased devices from CryptoBilis since March 2026 are eligible for a free exchange or refund. link
