Ledger confirmed that at least one hardware wallet sold through authorized reseller CryptoBilis contained an unauthorized electronic implant, with potential losses estimated at $93 million across 311 wallets on five blockchains. The reseller operates in Malaysia, Indonesia, and the Philippines.
Former Mt. Gox CEO Mark Karpelès discovered a hidden microcontroller module concealed behind the screen of a Ledger Nano X purchased in Malaysia, despite intact shrink-wrap packaging. Ledger has asked CryptoBilis to halt all hardware wallet sales while investigations continue.
“Based on information so far, it seems to be localized to a supply chain attack with one vendor.”
Tether has moved to freeze USDT stablecoins linked to the thefts. Binance founder Changpeng Zhao described the incident as a localized supply chain attack and urged industry-wide cooperation to trace and recover stolen assets.
Ledger stated its own backend systems and services show no signs of compromise, pointing toward physical tampering at the reseller level. The company is working with authorities and contacting affected users directly.
