Ledger wallet tampering suspected after reports of crypto thefts

Hardware wallets keep crypto keys on the device rather than online, so a thief usually needs hands on the wallet; investigators found a hidden circuit board under the screen of some Ledger wallets sold by reseller CryptoBillis. It captured the recovery phrase shown during setup and relayed it via an embedded SIM; reports say over $86 million was stolen, though Ledger says its own systems were not breached.
