Physical coercion — hardware wallet (2025)
ConstrainedCase description
In the aftermath of the January 2025 Ledger co-founder kidnapping, French authorities arrested 10 people aged 20–40, most of whom had prior criminal records. The ransom payment had been partially made in cryptocurrency before GIGN intervention, and investigators subsequently worked with Tether and exchanges to freeze approximately 95% of the funds transferred. The case drew attention to the systemic vulnerability of publicly identified cryptocurrency executives and their families. Security researchers noted that the WhatsApp number used by kidnappers was registered via a Southeast Asian phone number and a VPN, demonstrating the operational security sophistication of the group. French Interior Minister Bruno Retailleau subsequently announced meetings with the cryptocurrency industry to address rising crypto-related violent crime.
