Does competition in the crypto industry push Ledger to attack Trezor, or is it a salutary warning for all users? Behind this revelation, a major issue: the safety of wallets. Ledger has shown that the SAFE 3 and SAFE 5 models of Trezor had a critical flaw. A simple bypass of the firmware potentially made it possible to access user funds. How was this breach discovered and corrected?
Ledger highlights a disturbing fault at Trezor
Ledger Donjon, the Ledger cybersecurity research branch, discovered A critical vulnerability in the SAFE 3 and SAFE 5 wallets of Trezor. By studying the safety of these models, the researchers found that cryptographic operations were carried out on a vulnerable microcontroller to advanced attacks.
The problem ? A hacker could theoretically Edit the firmware and bypass integrity verificationmaking possible unauthorized access to digital user assets.
“” We believe that strengthening the crypto ecosystem benefits everyone “Said Charles Guillemet, CTO de Ledger.
A discovery lifting Questions about the robustness of competing wallets.
Trezor reacted quickly by applying a correctiveshowing his commitment to security. But this affair recalls a disturbing reality: security faults are not simple anomalies, but permanent threats.
If a breach has been clogged today, how many are still to be discovered in the world of crypto wallets?
Wallet Crypto: continuous safety race
Wallet hardware are supposed to be the ultimate safe For digital assets, but this case shows that none is infallible. Trezor introduced Secure Elementschips designed to protect private keys from physical attacks.
However, Ledger revealed that This protection could be bypassed via the microcontroller, making the flaw usable.
Faced with the threat, Trezor recalled that his firmware hasAn integrity verification To prevent any malicious change. But Ledger has shown that this protection could be bypassed by a determined attacker. Simple physical access would be enough to compromise a Wallet Crypto, a disturbing situation for altcoin and Bitcoin investors.
A few Standing figures ::
- $ 484,000 in crypto stolen during a previous flaw at Ledger in 2023;
- 270,000 LEDGER user email addresses compromised in 2020;
- 297 solo minors validated a bitcoin block against all expectations;
- 100 % of wallets remain theoretically vulnerable to certain advanced physical attacks.
If traders and digital asset holders thought that their wallet was breathtaking, this case reminds them that prudence is in order.
Cybersecurity: a permanent challenge for crypto wallets
In the world of digital assets, Cybersecurity is an endless fight. Trezor and Ledger strive to improve the protection of their wallets, but hackers are constantly improving their techniques. Each innovation leads to its share of vulnerabilities, transforming security into a cat and mouse game.
The latest fault highlights an underestimated risk: the Physical attacks via the supply chain. In theory, a malicious actor could compromise a crypto wallet even before its purchase by a user, thus opening an insidious breach in the protection of digital assets.
Ledger insists on the importance of Secure Elements and the integrity control of firmwares to avoid unauthorized access. However, even with these measures, threats are constantly evolving. As Trezor said:
In cybersecurity, the golden rule is simple: nothing is infallible.
A statement that resonates while attack methods are always more sophisticated.
Some worrying elements:
- 90 % of attacks on material wallets exploit physical or human flaws;
- Phishing remains the leading cause of cryptocurrency flight, even with secure wallets;
- Each year, hackers develop new methods to bypass existing protections.
How far should manufacturers go to secure the crypto wallets? Should we expect new flaws or innovations capable of eradicating these risks? One thing is certain, the crypto industry must redouble their vigilance, because the attackers, they never sleep.
This fault recalls that the safety of wallets is not only based on technology, but also on the vigilance of users. Ledger himself was the victim of phishing campaigns and data leaks in the past. Nothing is never completely secure in the crypto universe, and remaining alert remains the best protection.
