French authorities are investigating a rise in crypto-linked kidnappings after a 74-year-old man from Voiron in Isère survived a violent 16-hour abduction in January 2026. Police said attackers stormed his home and forced him to contact his son while demanding cryptocurrency, believing the family held significant digital assets.
The incident forms part of a growing pattern of organized groups targeting individuals linked to crypto through data leaks and online tracking.
As per a local report, the victim, identified as Jean, told investigators that his kidnappers assaulted him repeatedly while trying to extract access codes from his son. Authorities confirmed the group demanded €3 million before police intervention ended the case.
Rising Violence in Crypto-Linked Kidnappings
Jean told investigators that the attackers used repeated violence over several hours, including threats, forced movement, and physical assault. He said they filmed him to pressure his son into paying a ransom.
However, no payment was made after the son confirmed he did not control large crypto funds. Police later arrested three suspects aged between 19 and 23 during the operation.
Investigators said the group acted under instructions from a remote coordinator believed to be based abroad. They added that the attackers were recruited through social media and operated as low-level executors.
Moreover, authorities linked the same operational pattern to at least twenty kidnappings between 2023 and 2025, with activity increasing sharply in 2026.
Organized Networks and Digital Targeting
Police analysis shows that structured criminal groups increasingly rely on online intelligence and leaked databases. Besides hacking activity, attackers study public profiles and financial indicators to identify potential targets. However, officials said many victims have no actual cryptocurrency holdings.
Investigators also described a pyramidal structure in which coordinators operate from abroad while recruits carry out attacks locally. Hence, this structure complicates enforcement, as lower-level operatives rarely identify their leaders. France, so far, has recorded 41 crypto-related kidnappings since early 2026.
Speaking at Paris Blockchain Week, the French Interior Ministry said it has launched a national response plan to address the surge in attacks. Authorities said the plan aims to strengthen prevention systems and improve coordination among law enforcement agencies.
Meanwhile, insurers and security firms are developing new protection measures, including kidnap-and-ransom coverage for digital asset holders.
