Mark Karpelès, the former Mt. Gox chief, says Ledger knew about advanced spy implants in March. He criticized the company's response and called the situation “a five-alarm fire in the making.”
Why it matters
The allegation reaches beyond one hardware-wallet maker. Users rely on physical devices to protect private keys, so claims involving covert implants strike at the security assumptions behind self-custody. It also puts disclosure practices under scrutiny: what a company knew, when it knew it, and how it communicated the risk.
Market impact
No token price move is attached to the claim, but confidence is central to the hardware-wallet market. Ledger's handling of the allegation will shape how users and institutional customers assess device security, incident response, and trust in crypto custody providers.
