Karpeles warns Trezor wallets may be tampered, not just Ledger

Former Mt. Gox CEO Mark Karpeles warned that Trezor hardware wallets may have been compromised by sophisticated implants, suggesting the recent Ledger supply chain attack was not an isolated incident. The claim raises doubts about the physical security of self-custody devices used to store crypto. Traders holding assets on hardware wallets may reassess their storage setups, though no confirmed losses or affected devices were named.
