Someone has been quietly planting backdoors in Ledger crypto wallets, and nobody has pinned down who.
A new investigation is looking into how backdoors have ended up in Ledger hardware wallets, the small USB-style devices used to store cryptocurrency private keys away from internet-connected computers. The report does not land on a definitive answer. It raises the question without naming a company, a state actor, or a disgruntled insider. That open-ended framing is deliberate: the reporting suggests the source of the problem is genuinely unresolved, not just withheld for effect.
Ledger wallets sell on a single promise: your keys never leave the hardware, so a hacked laptop cannot drain your crypto. A backdoor built into the device itself breaks that promise at the root, no matter how careful the owner is. If the source of the problem cannot be identified, every owner is left trusting a device whose supply chain they cannot fully verify.
Hardware wallets were supposed to be the boring, bulletproof answer to crypto theft. An unresolved question about who is backdooring them is a reminder that boring and bulletproof was always aspirational.
