France Reports 90 Crypto-Related Attacks, Citing Data Risks

France recorded 90 crypto-related cases involving kidnapping, extortion, threats and violent theft from 1 January to mid-August 2026, according to official figures. Police made 223 arrests, while 126 people were imprisoned between January and July. Chainalysis counted 30 publicly reported attacks by mid-year, and Gart.io tracked 73 real-world attacks year to date; its figures put France ahead of other countries it monitors. The counts use different methods, and official year-on-year comparisons are unavailable because France began collecting data in 2026. Researchers say leaked personal and financial information may help criminals identify crypto holders and their addresses. Possible sources include a 2024 leak involving French tax information and a January 2026 Waltio breach affecting about 50,000 users. Chainalysis found that relatives and acquaintances featured in more than 40% of violent crypto incidents in France, suggesting threats can extend beyond holders themselves. Authorities are coordinating investigations through JUNALCO. The crypto-related attacks raise serious physical security and privacy concerns, but do not indicate a direct change in cryptocurrency prices or market fundamentals.
