Trezor confirmed that 3 Trezor Safe 5 wallets inspected from 48 affected users contained malicious circuit boards. The compromised devices were sold through CryptoBilis and its Tokopedia and Shopee stores between Aug 20 and Sep 23, 2026.
Why it matters
The implants were concealed between the motherboard and display, allowing them to capture recovery seeds and passphrases shown on the screen and transmit the data to attackers over cellular networks. This creates a hardware-level threat that can bypass the security expected from a trusted wallet. Trezor has not reported any stolen user funds.
Market impact
Trezor released firmware version 2.13.1 on Nov 11 to block data capture by the identified implants. The company also reduced its reseller network by approximately 80%, tightened procurement and warehousing controls, and offered free replacements or refunds to customers who bought devices from CryptoBilis since March 2026.
