French Authorities Probe Data Breach at Crypto Tax Platform Waltio
French cybersecurity officials are investigating a significant data breach at Waltio, a cryptocurrency tax reporting platform. The incident exposed sensitive personal information of approximately 50,000 users, predominantly French taxpayers.
The hacker collective Shiny Hunters has claimed responsibility for the attack, issuing ransom demands for the stolen data. Authorities warn the compromised information—including financial details—could fuel targeted attacks against cryptocurrency holders.
This breach emerges as European regulators implement stricter data protection frameworks for digital asset services. The incident underscores persistent security vulnerabilities in crypto-adjacent financial platforms despite growing institutional adoption.
