Ledger CTO responds to vulnerability FUD: The issue was fixed before it was disclosed, and users can safely use it by updating in a timely manner

Ledger's Chief Technology Officer Charles Guillemet stated that there has recently been "FUD" targeting Ledger in the market, as a smart contract security company claimed to have discovered vulnerabilities in the Ledger Ethereum application. Guillemet mentioned that there indeed were vulnerabilities related to certain Clear Signing processes in the Ledger Ethereum application, but these vulnerabilities were discovered by Ledger's security research team Donjon using AI-driven vulnerability research tools, and the fixes were completed and deployed two weeks ago. Users can obtain protection by timely updating their Ledger device firmware and applications.

The relevant security company contacted Ledger's bug bounty program only after the fixes were completed, did not follow responsible disclosure processes, and did not communicate with the bug bounty team, yet implied in subsequent content that the issue had not been resolved. This approach is not true security research but rather a way to create panic for attention. AI is changing the cybersecurity landscape, and both attackers and defenders can enhance efficiency with AI, but AI-driven security research can only truly enhance the security of the entire ecosystem when basic security principles such as responsible disclosure and pre-release verification are followed.

Guillemet finally reminded Ledger users to keep their device firmware, Ledger applications, and related software up to date to automatically receive the latest security fixes and research results. Users should not be influenced by the related "FUD" and should timely update their software and maintain safe habits.
