Certainly, French cryptocurrency faces increasingly more reasons to worry! A serious state affair has once again cast doubt this week: how an employee of the tax authority managed to betray her duty to serve criminal gangs in the industry.

An spy within the tax authority?

As attacks targeting cryptocurrency holders intensify, a case at the heart of the tax administration reveals an unprecedented level of criminal infiltration. In June 2025, an agent from the Île-de-France tax office, named Ghalia C., was placed under investigation for having passed confidential information from tax databases to criminals.

According to Le Parisien, the civil servant was accessing the 'Mira' database—reserved for handling sensitive tax files—without professional justification. Among the potential victims were prison guards, public figures such as Vincent Bolloré, and several crypto investors identified as preferred targets for extortion. In exchange for this data, she received payments via Western Union, a discreet transfer method favored in illegal networks.

The case broke open when the address of a prison guard, passed by the tax official to a criminal network, led to a violent assault. Searches conducted at the suspect's residence uncovered suspicious financial flows and a history of fraudulent connections. During her hearing on Monday, the accused confessed to the facts, without revealing the identities of the masterminds.

Already convicted for drug trafficking with inmates, she is also believed to have participated in similar operations in the Nancy region, where other incidents of intimidation against civil servants have been recorded. Authorities now fear the existence of a structured network exploiting human vulnerabilities within state services.

This case arises amid a troubling surge in targeted attacks against cryptocurrency holders. On January 5, 2026, in Manosque (Alpes-de-Haute-Provence), a woman was violently assaulted at her home by three masked men. The attackers were seeking access codes to her partner’s wallet.

After searching the residence and stealing a USB drive containing information related to digital assets, they fled. The victim, who managed to free themselves, was able to raise the alarm.

These two cases come at a bad time in the context of the rollout of DAC8, which allows tax authorities to automatically obtain all local crypto transactions, and the strengthening of the MiCA law for increasing traceability. The cherry on top: data from some Ledger clients have also leaked, adding another layer of threat for cryptocurrency holders. But in a world where even the tax authority is no longer trustworthy, do we really have reason to continue down this path?
