French encrypted tax platform Waltio has been hacked and is facing a ransomware attack, potentially exposing the data of approximately 50,000 users.

French cryptocurrency tax filing platform Waltio announced that it has been blackmailed by a hacker group called "Shiny Hunters." The group claims to have obtained the personal data of approximately 50,000 customers (most of whom are located in France) and is demanding a ransom. Waltio provides portfolio tracking and tax calculation services for cryptocurrency holders. The company stated that it has reported the incident to the police regarding the "attempted blackmail and disruption of automated data processing systems." Reports indicate that the hackers allegedly obtained the email addresses and account balance information of relevant customers as early as 2024. (Le Parisien)
