• Ledger Donjon identified microcontroller vulnerabilities in the Trezor Safe 3 and Safe 5 hardware wallets.
• Trezor has patched the flaw, ensuring user funds remain protected.
• The findings raise concerns about cryptographic operations outside the Secure Element.

Ledger’s security experts, Ledger Donjon, have found a critical flaw in some of Trezor’s hardware wallets, Safe 3 and 5. The weakness exists in the microcontroller, that is the device’s main computer.

According to Ledger, this could allow attackers to compromise users’ crypto assets through voltage glitching techniques – a hardware attack that disrupts a device’s power supply to cause errors and bypass security. 

Trezor’s Secure Element is designed to defend against physical attacks like this, but a design flaw reportedly allows a well-equipped hacker to…
