Data Breach at French Tax Authority Affects Approximately 678,000 People
The French Finance Minister confirmed that hackers breached the General Directorate of Public Finance in late June, stealing personal and professional taxpayer data.
The tracking platform FrenchBreaches reported that about 678,437 individuals were affected, equivalent to about 1% of France's population. An investigation is ongoing, and the exact number is yet to be confirmed.
Among the affected, nearly 27,000 had taxable income of at least €100,000, 386 exceeded €1 million, and 8 surpassed €10 million. The stolen database is being sold on the dark web for thousands of euros.
The data includes sensitive information such as names, birth dates, home addresses, phone numbers, and email addresses.
While cryptocurrency holders were not explicitly identified, the combination of income and identity information could help criminals target wealthy individuals for scams, burglaries, or kidnappings. France has recently become a hotspot for "ransomware attacks," where criminals use violent threats to force victims to hand over access to their crypto assets.
In market mechanisms, high-net-worth data circulating on the dark web increases targeted crime risks, driven by the tax system breach; the beneficiaries are the criminals purchasing the data, while the pressured parties are high-income taxpayers and cryptocurrency holders.

The General Directorate of Public Finance in France, as a core tax system, has long accumulated detailed income and identity profiles of taxpayers. This breach occurred through VPN credentials and internal search tools, exposing weaknesses in identity theft and remote access control.
In terms of capital pathways, hackers are packaging and selling data of high-income groups, motivated by the high incidence of "ransomware attacks" in France to convert tax records into targeted violent crime hit lists, with dark web transaction prices reflecting their immediate commercial value.
Similar cases can be seen in the previous leak of the French crypto tax platform Waltio and the incident of tax officials selling data of crypto investors; currently, high-net-worth individuals and cryptocurrency holders in Europe face a risk phase of escalation from cyber theft to physical violence.
Structural judgment falls under the intersection of regulatory changes and technological substitution: centralized tax databases become attack surfaces, with the mechanism being that a single system storing a large amount of identifiable wealth information can be converted into offline crime intelligence through one breach, forcing high-net-worth individuals to reassess the costs of data exposure and physical security.
