A former French tax official, Ghalia C., has been accused of leaking confidential information about cryptocurrency holders, raising concerns over potential security threats. The official allegedly abused her access to tax databases to gather data on crypto investors, including their locations and capital gains, which may have been leaked. Although there is no evidence of planned attacks against these individuals, the case underscores the vulnerability of tax systems to data breaches. As European authorities intensify their scrutiny of cryptocurrency assets, such leaks could pose significant risks to holders.
