But we saved everything 🙂.

Ledger previously halted an attempted prompt injection after a user rejected a malicious transaction, demonstrating the effectiveness of its security architecture. The incident highlighted the importance of user vigilance with signing requests. More recently, the company advised moving away from reliance on .env files as autonomous agents play a larger role in key management. Ledger maintains that improved key management practices are necessary to address ongoing security concerns.
