Ledger researchers discovered a laser-based hardware flaw in the TROPIC01 chip used by Trezor Safe 7; Trezor disputes funds are at risk.
Security & Exploits ·
Ledger's security team identified a laser-based hardware vulnerability in the TROPIC01 chip used by Trezor Safe 7. Trezor responded by stating that user funds remain unaffected by the flaw, disputing any immediate risk to holdings stored on the device.
The vulnerability exists within a Secure Element chip that handles critical cryptographic operations in the hardware wallet. Ledger's Donjon team uncovered the flaw during an audit, and Trezor subsequently disclosed the issue publicly rather than keeping it hidden.
The core disagreement centers on the practical threat level: while Ledger researchers documented a technical weakness exploitable through laser-based attacks, Trezor maintains the vulnerability does not translate into actual fund loss under real-world conditions. The specifics of how Trezor plans to remediate the flaw or whether firmware updates will be issued remain unclear.
