A former French tax official may have abused her position to leak data on cryptocurrency holders, increasing the risk of physical attacks against this group. Ghalia C., the former tax official, has been sentenced and is currently appealing charges including aiding and abetting organized crime. Investigations revealed that she used her access to confidential tax databases to gather information on potential targets, including cryptocurrency investors, and may have leaked their location and capital gains data. While there is no evidence that she planned any actual attacks against cryptocurrency holders, this case highlights the risk that tax systems can become sources of data breaches. As European tax authorities increasingly tighten their monitoring of cryptocurrency assets, such leaks could expose holders to greater security threats. (Cryptopolitan)
