Ledger Donjon Reveals Critical Flaw in Trezor's Safe 3 and Safe 5 Models

Is the competition in the crypto industry pushing Ledger to attack Trezor, or is it a timely warning for all users? Behind this revelation lies a major issue: the security of wallets.

The fierce competition in the crypto industry has led to an interesting revelation.

According to Ledger, Trezor’s Safe 3 and Safe 5 models had a critical flaw that could be exploited to gain access to users’ funds. However, Trezor responded promptly by applying a patch for this flaw.

This discovery is sure to spark debate about the relative security of different hardware wallets.

According to reports by Ledger Donjon, the cybersecurity research branch of Ledger, Trezor’s wallets Safe 3 and Safe 5 had a critical vulnerability.

While studying the security of these models, researchers at the Ledger company found that cryptographic operations were performed on a microcontroller, which is vulnerable to advanced physical attacks.

The problem is that a hypothetical attacker could modify the firmware and bypass the integrity check, making it possible to access users’ digital assets.

“We believe that strengthening the crypto ecosystem benefits everyone,” said Charles Guillemet, CTO of Ledger.

This discovery is sure to raise questions about the robustness of competing wallets.

Trezor responded promptly by applying a patch, demonstrating its commitment to security.

However, this incident highlights a troubling reality: security flaws are not just anomalies, but ongoing threats.

If a breach has been patched today, how many more remain to be discovered in the world of crypto wallets?

Crypto wallet: the race for security continues

Hardware wallets are supposed to be the ultimate vault for digital assets, but this incident shows that none are infallible. Trezor introduced Secure Elements, chips designed to protect private keys against physical attacks.

However, Ledger revealed that this protection could be bypassed via the microcontroller, rendering the flaw exploitable.

Facing the threat, Trezor recalled that its firmware has an integrity check to prevent any malicious modifications. But Ledger demonstrated that this protection could be bypassed by a determined attacker. A simple physical access could compromise a crypto wallet, a worrying situation for altcoin and bitcoin investors.

Some notable figures:

If traders and holders of digital assets thought that their wallet was impregnable, this incident reminds them that caution is necessary.

Cybersecurity: an ongoing challenge for crypto wallets

In the world of digital assets, cybersecurity is a never-ending battle. Trezor and Ledger strive to improve the protection of their wallets, but hackers continue to refine their techniques. Every innovation brings its share of vulnerabilities, turning security into a game of cat and mouse.

The latest flaw highlights an underestimated risk: physical attacks via the supply chain. In theory, a malicious actor could compromise a crypto wallet even before it’s purchased by a user, thus opening a sneaky breach in the protection of digital assets.

Ledger emphasizes the importance of Secure Elements and firmware integrity checks to prevent unauthorized access. Yet, even with these measures, threats are constantly evolving. As Trezor stated:

In cybersecurity, the golden rule is simple: nothing is infallible.

A statement that resonates as attack methods become increasingly sophisticated.

Some concerning elements:

How far will manufacturers have to go to secure crypto wallets? Should we expect new flaws or innovations capable of eradicating these risks? One thing is certain, the crypto industry must redouble its vigilance, as attackers, themselves, never sleep.

This flaw reminds us that the security of wallets does not solely rely on technology, but also on the vigilance of users. Ledger itself has been a victim of phishing campaigns and data leaks in the past. Nothing is ever completely secure in the crypto universe, and staying alert remains the best protection.
