Waltio, a French crypto tax software provider, is battling extortion threats from ShinyHunters, a notorious hacker collective that claims to hold the personal data of nearly 50,000 users. The group says it will publish users’ 2024 tax reports unless Waltio pays a ransom. Waltio says its core services and production systems remain secure and that no sensitive banking information or crypto access credentials were compromised. The company has reported the incident to France’s cybercrime unit and is treating the situation as an active criminal matter. ShinyHunters has a history of targeting high-profile organizations and crypto-related platforms. According to Protos, the group previously extorted AT&T for six bitcoins (about $373,000 at the time), threatened to leak Ticketmaster data, and has targeted major Indian crypto exchanges. The episode underscores growing threats to platforms that store or process sensitive financial and tax data for crypto users, and highlights the persistent risk of ransomware and extortion impacting the broader digital-asset ecosystem.
