French authorities recorded 90 cases of kidnapping, extortion, threats and violent theft connected to cryptocurrencies between Jan. 1 and mid-August 2026, according to figures provided by the French Interior Ministry. That equates to a new case roughly every two and a half days, alongside 223 arrests and 126 imprisonments from January through July.

The ministry confirmed the data covers a new reporting regime, so no year-on-year comparison exists. "We do not have the statistics on these items for 2025, as the recording of events began on Jan. 1, 2026," the ministry said.

How does France compare globally?

The official figures far exceed independent public trackers. Chainalysis counted 30 publicly known violent crypto incidents in France through mid-2026, while noting the true scale was "almost certainly larger." Security firm Gart.io has tracked 73 attacks in France year-to-date, placing it first worldwide ahead of the United States on 66 real-world attacks and the United Kingdom on 27.

Bitcoin security advocate Jameson Lopp's long-running directory of physical attacks documents 365 cases across 60 countries between 2014 and 2026. France tops that leaderboard.

The violence has also spread beyond Paris. Chainalysis recorded incidents in Strasbourg, Marseille, Grenoble, Toulouse and Nantes. Of the victims with known residency, 93% were French — criminals are not targeting crypto-wealthy tourists.

What is driving the surge?

Chainalysis head researcher Eric Jardine said the surge is "very likely" due to a "significant data breach." He told Cointelegraph: "These sort of breaches expose more than financial information; they reveal who holds crypto, where they live, and how to find them."

Jardine pointed to the 2024 compromise of the French tax authority, in which a Paris-area tax official "leaked PII, financial and crypto holding information on French taxpayers." Chainalysis records show attacks surged from late November of that year. A second incident followed in January 2026, when crypto tax reporting firm Waltio disclosed a breach affecting some 50,000 users, giving attackers further targeting data.

Francis Pouliot, founder of Canadian Bitcoin exchange Bull Bitcoin, has repeatedly challenged Europe's DAC8 crypto reporting rules in France, which expand tax reporting and information-sharing requirements across the European Union. "DAC8 has transformed the concept of Know Your Customer into Kill Your Customer," he said, describing France as the "crypto kidnapping capital of the world."

Who are the targets?

The victim profile has shifted. Globally, relatives and acquaintances accounted for roughly 25% to 30% of violent crypto incidents by early 2026, according to Chainalysis. In France, the proportion exceeded 40%.

In May 2026, six men allegedly attempted to abduct the wife of The Sandbox co-founder Sébastien Borget from the couple's home in Villenoy, with one attacker posing as a delivery driver. In August, a couple in rural France reportedly endured three separate break-in attempts after buying a property previously owned by crypto millionaires whose tax information and address had leaked onto the dark web.

In a 2025 case, the father of a crypto entrepreneur was abducted in Paris and held for two days, with kidnappers cutting off part of his finger and sending it to his son while demanding $5.6 million in cryptocurrency.

Jardine said the targeting of relatives and associates "suggests criminals are doing reconnaissance before they act," whether by "monitoring social media, analyzing blockchain data, using leaked information, or receiving tips from insiders."

What is the official response?

French authorities now treat the attacks as organized crime, coordinating investigations through JUNALCO, the country's specialized organized crime jurisdiction. The operational lesson for holders is stark: hardware wallets and seed-phrase hygiene do not help once an attacker already knows who holds crypto and where they live.

With the Interior Ministry's incident recording now running a full cycle from January 2026, the first official year-on-year comparison — and any measurable effect of JUNALCO's coordinated crackdown — should emerge in early 2027.
