Pourquoi c'est important
France is experiencing a significant increase in crypto wrench attacks, where criminals use physical violence to extort victims. The government is responding with new security measures and support for the crypto sector.
France averaged nearly three crypto wrench attacks per week this year, with French Interior Minister Laurent Nuñez confirming there were 77 kidnapping, extortion or attempted extortion incidents linked to crypto in the first half of 2026.
Nuñez said Tuesday that the 77 incidents recorded so far this year are up sharply from the 45 recorded in all of 2025, according to local outlet BFM Business.
“These are serious matters, and your concern is legitimate,” he told the Association for the Development of Digital Assets (ADAN) as he promised more government support.
France has become one of the biggest hot spots for crypto wrench attacks, where criminals use physical violence to coerce victims into handing over crypto. Approximately 11% of French people own cryptocurrencies, according to ADAN, which equates to about 7.3 million people.
France’s rapid alert and protection system
Earlier this year, French authorities launched a dedicated prevention platform and a rapid-alert and protection system for crypto holders and professionals, which has attracted 724 sign-ups so far, Nuñez said.
Nuñez said that emergency measures have resulted in 200 arrests, with one recent attacker being arrested within eight hours on Friday, thanks in part to the victim using an emergency identification hotline.

Nuñez promised a “more ambitious” three-part plan to reinforce security measures for the crypto sector. This includes stronger intelligence-sharing, since criminal networks are often based abroad, a deeper partnership with ADAN and better operational coordination between security services.
French wrench attacks on the rise
Blockchain security firm CertiK reported in May that wrench attacks globally were up 41% in the first four months of 2026, compared with the same period last year, with most attacks in Europe.
The firm said France is the “epicenter” of attacks because of the presence of several flagship industry companies and their executives, a “culture of flexing and voluntary doxxing that remains deeply embedded in the community,” and proven exposure from numerous sensitive data leaks.
David Balland, co-founder of French hardware wallet maker Ledger, was kidnapped and held for ransom along with his partner in January 2025 before being rescued by police.
Ledger suffered one of the industry’s most damaging data breaches when its customer database was hacked in 2020, resulting in the leak of more than 270,000 personal records and a wave of phishing and wrench attacks that continue to this day.
“France ranks among the most targeted countries in the world for this type of breach,” CertiK said.
