France's official tally of crypto kidnapping and extortion runs three times Chainalysis's count

The ministry's 90 cases are three times the 30 that Chainalysis counted ^[21], but the two figures cover different ground. The ministry's category includes threats and extortion alongside kidnapping and violent theft, and its window runs from Jan. 1 to mid-August ^[1][2]. Chainalysis counted only publicly known violent incidents through mid-2026, and said the true scale was "almost certainly larger" ^[3]. Set against Gart.io's 73 attacks for the year, the ministry figure is about 1.2 times higher ^[12][22]. It is harder to say whether any of this is new. "We do not have the statistics on these items for 2025, as the recording of events began on Jan. 1, 2026," the ministry said ^[4]. The public series does show growth: Crypto Briefing reported 19 public incidents in France in all of 2025 and 30 in the first half of 2026 ^[5]. The first-half figure is about 3.2 times the 2025 half-year pace ^[23]. The enforcement numbers point to crews. Authorities recorded 223 arrests, and 126 people were imprisoned from January to July ^[6]. That works out to about 2.5 arrests for each recorded case ^[24]. Crypto Briefing put arrests at roughly 200, and reported that by spring 88 people, ten of them minors, had been charged across 12 cases ^[7][13]. That is an average of about seven defendants a case ^[25]. In May, six men allegedly tried to abduct the wife of The Sandbox co-founder Sebastien Borget from the couple's home in Villenoy, with one posing as a delivery driver to get her to open the gate ^[14]. The targeting starts with records. Chainalysis head researcher Eric Jardine told Cointelegraph the surge was "very likely" due to a "significant data breach" ^[8]. "These sort of breaches expose more than financial information; they reveal who holds crypto, where they live, and how to find them," he said ^[9]. He pointed to a 2024 compromise in which a Paris-area tax official "leaked PII, financial and crypto holding information on French taxpayers" ^[10]. Chainalysis records show attacks surged from late November that year ^[10]. A January 2026 breach at crypto tax firm Waltio affected some 50,000 users ^[11], and 93% of victims with known residency were French ^[15]. A holder can keep their keys offline and say nothing in public and still turn up in a tax file that an official can leak ^[10]. DAC8, the EU rule set, expands tax reporting and information-sharing requirements for crypto users ^[19]. "DAC8 has transformed the concept of Know Your Customer into Kill Your Customer," said Francis Pouliot, founder of the Canadian exchange Bull Bitcoin ^[18]. The ministry figure can still mislead. If most of the 90 are threats and extortion in which nobody was seized, the physical risk sits nearer the 30 to 73 range the trackers show ^[3][12]. If a handful of crews account for most cases, the arrests ^[6] would bring the rate down faster than any current count suggests. And because recording only began this year ^[4], a higher 2027 figure would partly reflect better logging. I think the ministry figure is closer to the real scale, since Chainalysis expects its own count is low ^[3]. The counter-case is that a category that includes threats will always outrun a tally of violent incidents ^[1][3]. The finding about relatives holds whichever total is right, because it comes from Chainalysis's own incident set. In France, relatives and acquaintances made up more than 40% of violent crypto incidents, against 25% to 30% globally ^[16]. If that share applied to the ministry's 90 cases, more than 36 of them would have targeted someone other than the holder ^[26]. In 2025 the father of a crypto entrepreneur was abducted in Paris and held for two days ^[20].
