anchored·5SfwX7…uQnLSummary
In October 2026, Ledger opened an investigation into reports of large-scale wallet drains affecting customers in Southeast Asia who bought hardware wallets through CryptoBilis, a reseller authorized in Indonesia, Malaysia, and the Philippines. On-chain researchers estimated losses ranging from roughly $72 million to over $86 million, and separate reporting cited an alleged hidden hardware implant capable of exfiltrating seed phrase data over a cellular network, though Ledger had not confirmed the cause, the total loss figure, or the number of victims as of this writing. This page concerns this specific incident; it does not restate the overall trust assessment of Ledger's existing profile.
