Ledger probes supply chain attack tied to over $86 million in crypto losses

Ledger confirmed that at least one wallet sold through Southeast Asian reseller CryptoBilis contained an unauthorized physical implant that spied on the screen. Reported crypto losses have reached at least $86 million, with some estimates above $100 million. CryptoBilis has halted hardware wallet sales.

• Losses from the October 9 draining incident are estimated at $86 million or more
• The implant near the display captured screen data while the Secure Element stayed intact
• Standard integrity checks cannot detect unauthorized physical modifications
• CryptoBilis stopped selling wallets as Ledger works with authorities
