Key Points:

• Jameson Lopp, Chief Security Officer at Casa, estimates that France is the epicenter of roughly 25% of all global wrench attacks—violent, real-world assaults targeting cryptocurrency holders.
• Wrench attacks involve kidnapping, torture, or coercion to gain access to private keys, hardware wallets, or crypto transfers, bypassing the digital security of blockchain networks.

Notable Incidents in France

January 2025:

• David Balland, co-founder of Ledger, and his wife were kidnapped near Vierzon.
• Attackers demanded a €10 million ransom, but French authorities rescued the couple after nearly 60 hours and arrested five suspects.

May 2025:

• The father of an unnamed crypto entrepreneur was kidnapped and subjected to torture, including electrocution, with millions demanded in ransom.
• A daylight attempt in Paris’s 11th arrondissement targeted the daughter and toddler of a Paymium CEO. Masked assailants posing as delivery personnel were thwarted by the father and neighbors.

June 2025:

• A 23-year-old private crypto investor in a Paris suburb was kidnapped while running errands. Attackers forced him to call his partner and hand over a bag containing his hardware wallet and cash.

Recent Arrests:

• Last week, six men, including two minors, were arrested in France for planning to kidnap a man to steal his cryptocurrency.

Implications for Crypto Security

These attacks highlight a growing physical security risk for crypto holders, even as digital wallets and blockchain networks remain highly secure. Experts urge investors to:

• Exercise discretion regarding personal wealth and crypto holdings.
• Use multisig wallets, offline cold storage, and trusted custodial services.
• Implement personal security measures for themselves and family members.

Lopp warns that as crypto adoption grows, the risk of violent targeting may increase, particularly in France, which has emerged as a global hotspot for these crimes.
