Ledger Warned of Tampered Wallet Risk Months Before Crisis, Karpelès Says

The significance here is less about the technical flaw than about the timeline: a warning received months in advance reframes the crisis from an unforeseen exploit into a question of response. That distinction matters most for Ledger's hardware-wallet rivals and for the self-custody users who treat device integrity as the last line of defence, since it shifts scrutiny onto disclosure and escalation practices rather than engineering alone. Whether the warnings were specific enough to act on, and how the company characterises that gap, is the open question.
