Trezor Resolves Critical Security Vulnerability Exposed by Ledger’s Research Team
Trezor, a leading provider of hardware wallets, has swiftly addressed a security issue discovered in its Safe 3 and Safe 5 models.
This vulnerability, found by Ledger’s open-source research division, was related to the microcontroller of these devices. While Trezor had already implemented secure features to protect users, including Secure Elements to guard against basic hardware attacks, Ledger identified that cryptographic operations on the microcontroller could leave these models susceptible to more sophisticated threats.
Trezor acted promptly to fix this issue, reassuring users that their funds remain secure. Charles Guillemet, Ledger’s CTO, emphasized the importance of improving the overall ecosystem’s security, as it is essential for fostering broader crypto adoption. Despite having strong security measures like Secure Elements, which prevent certain types of attacks, the microcontroller flaw presented another potential risk.

The vulnerability allowed attackers to bypass a firmware integrity check, though this loophole has now been patched. Trezor has not disclosed the exact method of the fix, but the company reassured customers that no further action is necessary, and that their funds are safe.
This update highlights the ongoing challenges of cybersecurity in the cryptocurrency space, as even industry leaders like Ledger have faced their own security breaches. In December 2023, Ledger experienced a significant hack, resulting in the theft of hundreds of thousands of dollars in crypto assets. This serves as a reminder that no system is completely invulnerable, and users should always purchase hardware wallets from official sources to reduce risks.
