⚡️🚨 ALERT - Ledger hardware wallet implants were discovered over a year before this week's supply-chain attack revelations
Renowned hardware security researcher and computer engineer Joe Grand, also known as “Kingpin,” explains how he was contacted in August 2025 by a man in Thailand who had discovered a compromised Ledger Nano X.
The man had purchased a cheap Ledger online to replace the battery in his existing device.
When he opened it, he discovered a smaller battery, unauthorized circuitry, additional wiring, and an antenna.
After posting his discovery on Reddit and reportedly receiving little interest from local police, he contacted Grand to investigate.
The discovery came more than a year before the Ledger supply-chain attack became a major public controversy, with nearly $100 million in cryptocurrency reportedly stolen this week.
