Waltio, a French cryptocurrency platform, is facing extortion threats after hackers accessed data from approximately 50,000 user accounts. The company reported the incident on January 21, 2026, citing a sophisticated cyberattack that compromised certain data.
"This Friday morning, we filed a complaint for attempted extortion and violation of an automated data processing system. On January 21, 2026, we received a threat of extortion following a particularly sophisticated attack," the company stated.
The breach was linked to the Shiny Hunters hacking group, which reportedly stole user data, including tax reports for 2024 that contain email addresses, profits or losses, and asset balances. Waltio, which serves around 150,000 users, reassured clients that the breach did not expose passwords, API keys, wallet addresses, or any sensitive data that could enable fund transfers.
Waltio's CEO, Pierre Morize, emphasized that the primary risk arises from potential social engineering fraud, where attackers might impersonate customer support to trick users. He advised clients to verify the authenticity of communications from the company and to be cautious of unsolicited contact.
