Hackers have targeted French crypto accounting platform Waltio. The cybercriminals extorted the company after obtaining sensitive company data. French feds are now investigating the incident. DL News reached out to Waltio for comment, but did not immediately receive a response.
Bitcoin developer Jameson Lopp flagged the incident on X Friday, describing it as “more terrible news for French cryptocurrency users.” A number of high-profile crypto crimes have happened in the European nation over the past year. Most notably in 2025, crooks kidnapped Ledger’s co-founder, David Balland, holding him and his wife for 24 hours before being released. French daily Le Parisien reported that data from 50,000 Waltio customers had been stolen.
Waltio CEO Pierre Morizot said in a statement that hackers got user emails and gains and losses from the 2024 tax reports. He said the biggest risk would be cybercriminals reaching out to clients through social engineering scams. Social engineering attacks can take many forms, such as sending victims malicious links via email or calling them and pretending to be someone else. The objective, however, is the same: Getting additional information, such as key phrases to a crypto wallet, that would let them steal users’ funds.
