A French tax agent leaked the personal data of cryptocurrency holders after accessing unauthorized databases, creating a broader security risk for investors across Europe.
A French tax collector is reported to have leaked confidential data of cryptocurrency owners, which is a cause for concern regarding data security.
On June 30, 2025, a court sentenced 32-year-old Ghalia C. to prison after convicting her of complicity in an attack on a prison official and criminal conspiracy.
According to French media outlet Le Parisien, the ex-agent has sought out high-profile crypto investors, hacking the tax authority databases without permission and targeting prominent individuals and cryptocurrency experts.
An attack on a prison guard triggered the inquiry, which caused the police to learn that Ghalia C. had revealed the personal information of the guard. Additional investigations revealed that she had a history of performing unauthorized searches in her database.
Database Access Exposed Private Holdings
Ghalia C. assembled profiles of targets with tax information, which comprised the addresses and capital-gain information of cryptocurrency holders. She had studied the specialists and the private investors in society.
According to French media outlet Le Parisien, the tax agent was targeting several categories of clients, including prison officers and crypto-investors, and the police believe she was hired by an unknown sponsor.
Tax authorities now widely record cryptocurrency ownership in their databases. European citizens doubled their crypto exposure between 2022 and 2024. Governments also made it mandatory to report certain crypto holdings exceeding $5,000.
France is considering new digital property taxes that would impose a 1% annual levy on assets exceeding 2 million, including those held in self-custodial and offshore wallets.
