The French tax authorities may have leaked information of cryptocurrency owners.

European tax authorities are tightening monitoring of cryptocurrency ownership, but this control is also becoming a new source of risk. In France, a recent case shows that access to tax databases can expose crypto investors to serious personal security threats. A former French tax official, Ghalia C., has been investigated and imprisoned for aiding organized crime after being accused of leaking sensitive data, including information related to cryptocurrency owners.

Investigations reveal that she may have used the confidential tax system to search for famous individuals and crypto investors, thereby building profiles containing information about their location and capital gains. Although no direct attacks have been reported in this case, France has seen an increase in organized attacks targeting crypto owners. The expansion of reporting requirements and identity linking is raising serious concerns about privacy and personal safety.
