Ledger has confirmed that a hidden spy chip (reportedly a secret eSIM) implanted in counterfeit or tampered hardware wallets was behind a wave of crypto thefts, reportedly totaling around $92 million according to crypto.news (Bleeping Computer, October 12; crypto.news, October 12; Heise, October 12). The chip allegedly allowed attackers to exfiltrate private keys or signing data from compromised devices sold to unsuspecting users. The incident raises significant supply-chain security concerns for the hardware wallet industry and crypto custody more broadly, and is likely to prompt scrutiny of distribution channels and anti-tamper measures across the sector.
