French law enforcement officials are grappling with a sharp increase in so-called wrench attacks against cryptocurrency holders, where assailants physically threaten or assault victims to compel transfer of digital assets. The Paris Police Prefecture reported 217 such incidents in the first quarter of 2026, representing a 215% increase from the same period last year.
Market Context
The surge in physical attacks on crypto holders mirrors a broader trend observed across Western Europe, where the combination of high crypto adoption and insufficient security awareness has created what analysts describe as a target-rich environment for criminal actors. France's position as the third-largest crypto market in Europe, with estimated retail holdings exceeding €12 billion, has made it a focal point for both opportunistic criminals and organized groups. The phenomenon, dubbed wrench attacks in industry parlance after the tool often used as a threat weapon, represents a troubling evolution from purely digital theft to physical coercion.
Analysis
On-chain analytics firm Chainalysis confirmed in its latest Midyear Threat Report that physical attacks on crypto holders now account for approximately 7% of all theft-related incidents in France, up from just 2% in 2024. The attacks typically involve perpetrators who monitor social media for signs of substantial crypto wealth, then confront victims at their residences or in public settings. French prosecutors note that many incidents involve perpetrators who specifically target known crypto traders, suggesting either inside information or sophisticated reconnaissance. The emergence of so-called "crypto kidnapping" schemes, where victims are held until transferring assets, has particularly alarmed authorities. Digital rights advocates argue that the anonymous nature of blockchain transactions makes these attacks especially dangerous, as victims have limited recourse once funds are transferred.

What to Watch
French legislators are currently debating amendments to the 2024 PACTE law that would require crypto exchanges to implement enhanced customer verification for large withdrawals, potentially including biometric confirmation. The National Assembly is expected to vote on the measure by late May. Security experts advise crypto holders to avoid discussing holdings publicly and consider using multi-signature custody solutions that require multiple approvals for transactions. The French Ministry of the Interior has launched a public awareness campaign targeting high-value crypto holders, emphasizing operational security practices.
