France Records 90 Attacks on Crypto Holders in Seven Months

The Interior Ministry has registered 90 cases of kidnapping, extortion, threats, or violent theft involving crypto assets between January 1 and August 15, 2026, averaging one case every two and a half days. This figure, shared with CoinTelegraph, places France at the forefront globally for physical attacks on cryptocurrency holders. Authorities have also made 223 arrests and 126 incarcerations during the same period, highlighting the significant police response. No annual comparison is available, as tracking of incidents only began on January 1, 2026.

90 Attacks on Crypto Holders in Seven Months

The 90 recorded cases include kidnappings, extortions, and break-ins where attackers demand either the seed phrase or an immediate transfer of funds. According to the ministry, 93% of known victims resided in France, indicating that criminals primarily target local residents rather than wealthy tourists. The phenomenon has spread beyond Paris, affecting cities like Strasbourg, Marseille, Grenoble, Toulouse, and Nantes, as confirmed by Chainalysis.

Jameson Lopp, a Bitcoin security advocate, has maintained a registry of over 365 incidents across 60 countries since 2014, with France consistently leading. This concentration reflects, according to him, France's high visibility in European investigations and the density of crypto users. The tally paints an alarming picture for French market players, whose physical wallets are increasingly at risk.

223 Arrests and 126 Incarcerations Registered

The same dataset indicates 223 arrests between January and July 2026, of whom 126 have already served prison time. These numbers reflect a zero-tolerance policy by law enforcement but do not measure long-term effectiveness due to the lack of comparable historical data. The ministry notes that cases remain under investigation, which could lead to changes in the number of convictions.

The incarceration rate represents nearly 57% of arrests, a high ratio underscoring the severity of the crimes. Authorities use these prosecutions as a deterrent, though cybersecurity experts emphasize that prevention primarily relies on data protection.

Chainalysis Logs 30 Violent Incidents, Actual Number Likely Higher

Chainalysis, an on-chain analytics firm, has documented 30 known violent incidents in France up to mid-2026 while acknowledging the actual number is "almost certainly higher." This underreporting stems from the difficulty in identifying crimes where victims do not report incidents or where evidence is limited.

Eric Jardine, Principal Researcher at Chainalysis, told CoinTelegraph that the surge is "very likely due to a significant data breach." In French, he explained that data breaches not only expose financial information but also reveal who owns cryptocurrencies, where they live, and how to locate them. This exposure creates fertile ground for "wrench attacks."

Gart.io Ranks France First with 73 Attacks, Leading the U.S. (66) and the U.K. (27)

Gart.io, a cybersecurity firm, has tracked 73 attacks in France since the beginning of the year, surpassing the 66 reported in the U.S. and the 27 in the U.K. This ranking confirms Chainalysis' findings and highlights that France suffers more crypto-related physical crimes than any other studied country.

Gart.io's data shows that home break-ins are the most frequent incident type, with a notable increase in the first half of 2026. This trend indicates that criminals prioritize targets where they can quickly access offline storage devices, such as hardware wallets.

Data Breaches: Identified Trigger Factor

The link between attacks and a massive data breach has been highlighted by Chainalysis researchers. According to Eric Jardine, the breach allowed criminals to obtain wallet lists, associate each address with real identities, and plan targeted raids. This dynamic contrasts with traditional cybercrime where theft occurs solely online.

Experts stress that personal information protection becomes crucial for crypto holders. They recommend using cold storage solutions, diversifying addresses, and employing mixing services to obscure links between identity and wallet.

Security Implications and Outlook for Crypto Assets in France

In response to this wave of violence, the French government has announced plans to strengthen police resources dedicated to cybercrime and create a specialized intervention unit for "wrench attacks." This initiative aims to reduce the time between incident reporting and apprehension.

For investors, the situation necessitates a reassessment of operational risks. According to the secure trading guide by TradeXora, it is advisable to prioritize platforms offering physical theft insurance and adopt robust cybersecurity practices. The current security climate could also influence demand for institutional custody services, presenting new opportunities for sector players.
