Violent 'Wrench Attacks' on Crypto Holders Steal Over $30 Million in First Half of 2026, France Emerges as Hotspot

Aug 4, 2026

Violent physical 'wrench attacks' on cryptocurrency holders escalate in the first half of 2026, stealing over $30 million globally. France emerges as the primary hotspot, driven by a 2024 data breach where a tax official allegedly sold dossiers of high-net-worth holders. Attackers increasingly target victims' families, with relations targeted in over 40% of French cases. In response, French authorities make 200 arrests, while criminals use sophisticated decentralized finance tools to launder the stolen funds.
