French encrypted tax filing platform Waltio suffers ransomware attack and data breach, potentially affecting nearly 50,000 users.

PANews reported on January 23 that, according to Le Parisien, the French cryptocurrency tax filing platform Waltio announced it had been blackmailed by a hacker group called "Shiny Hunters." The group claims to have obtained the personal data of approximately 50,000 of the platform's customers (most of whom are located in France) and is demanding a ransom.

Waltio, a company that provides portfolio tracking and tax calculation services for cryptocurrency holders, has reported the incident to the police regarding an "attempt to extort and compromise its automated data processing system." The report indicates that the hackers allegedly obtained the clients' email addresses and account balance information as early as 2024.
