Hardware wallet providers are constantly working to improve the security of their devices, as the safety of users’ crypto assets is of utmost importance. Recently, competitor firm Ledger’s open-source research arm discovered a vulnerability in the microcontrollers of Trezor’s Safe 3 and 5 models. This flaw could potentially make the devices vulnerable to advanced attacks.

Trezor quickly took action and patched up the security flaw, as confirmed by Ledger’s chief technology officer Charles Guillemet in a recent post. Guillemet also emphasized the importance of making the entire crypto ecosystem more secure, especially as the adoption of digital assets continues to grow.

Trezor had already implemented “Secure Elements” in their devices to protect users’ PIN codes and cryptographic secrets. However, Ledger found that the microcontroller in Trezor’s two-chip design for the Safe 3 and 5 models could still be exploited. This issue has since been resolved by Trezor, though the details of the fix have not been disclosed.

Trezor has assured users that their funds remain safe and no further action is required. However, the company also acknowledged that in the world of cybersecurity, nothing is completely unbreakable. This is why they have implemented multiple layers of defense against supply chain attacks and always advise users to purchase from official sources.

It’s worth noting that Ledger has also faced security vulnerabilities in the past, with a hacker stealing $484,000 worth of crypto assets in December 2023. Another threat actor also breached Ledger’s systems and published the mailing addresses of around 270,000 customers in June 2020.

In the end, it’s crucial for hardware wallet providers to constantly improve their security measures to protect users’ assets. As the crypto industry continues to grow, it’s important for users to also take precautions and purchase from official sources to minimize the risk of potential attacks.
